00:01My name is Simon Woo. I'm here with my colleague Robert Berger, who will be showing you all the demos.
00:06And today we will be presenting Using Imagery in Raster Data in ArcGIS.
00:13So what exactly do we mean by using imagery in raster data?
00:16Here's our, the outline of our presentation.
00:20If you see something that's not on here that you were expecting, we understand your time is very valuable...
00:26...and if there's another session you thought that you might want to attend, feel free to get up...
00:31...and attend something that would be more along the lines of what you were looking for.
00:37So the presentation will start out with a simple, different varieties and types of raster data that you might add to ArcGIS...
00:46...and some of the raster properties that are fairly important for knowing how to use the rasters and what might be wrong with your raster.
00:55Then we'll go into displaying and rendering your imagery, followed by displaying a mosaic dataset.
01:01A mosaic dataset is one of our new features in ArcGIS 10. It's a new raster data model available.
01:10And then we'll talk about processing and new imagery.
01:15And finally we'll go over a summary of what's new in ArcGIS.
01:19Throughout the presentation, we'll go over whatever may be new in ArcGIS whenever that particular topic comes up...
01:26...but we'll summarize it again later at the end and include other things that may not have made it into any of our other slides.
01:33And we'll end off with any questions and comments you may have.
01:36We do try and ask that you hold your questions and comments until the end.
01:42We have a lot of content to cover, and there's a good chance that...
01:45...one of Robert's demos or one of my later slides may answer one of your questions.
01:49If not, we'll definitely set aside some time for your questions, comments.
01:54We're also downstairs in the Geodatabase Island area, and we're right beside the Imagery Island area, as well.
02:04So just to make sure, did everyone get a feedback sheet. If...and if you did, make sure you have the right title on it...
02:09...title being Using Imagery in Raster Data.
02:12If not, everyone go ask that student assistant for a new sheet.
02:24Okay. So let's start out and just look at a bunch of different types of rasters that you might be adding to ArcGIS.
02:33A lot of people like using elevations and hillshades, aerial imagery, satellite imagery, scan maps, and pictures and graphics...
02:47...and a lot more as well.
02:51And then when you add these varieties of imagery into ArcGIS, traditionally people use files on disc or a geodatabase.
03:01With files on disc, we're talking about everything from a GRID, a TIFF, an IMG, BMPs, so on and so forth...
03:08...basically, any of the 65-plus file formats that ArcGIS can read.
03:15And then there's the geodatabase, there's... in which you could add in raster datasets, mosaic datasets, and raster catalogs.
03:25So what is this mosaic dataset thing that we've added to ArcGIS 10?
03:30Well, we don't want to go into too much detail about that since it's mainly a managing issue.
03:34We'll just simply say that it's, it's a lot like the raster catalog in the way it's stored.
03:40It's a table. Each of the rows stores a raster dataset. Nothing new, nothing too new there.
03:48But we've added in a lot of new capabilities, which were lacking in the raster catalog...
03:55...and we've added in the ability to grab the metadata and load them into the attribute fields whenever they're available.
04:04So other than the fact that there's a...
04:07...catalog behind the scenes, we tried to make it more like a user experience of a raster dataset...
04:16...and other areas that you would add raster data from.
04:20Hopefully a lot of you are already using these. If not, try to look for these in the future.
04:25ArcGIS Online has most of these on the plenary. There's a lot of basemaps available...
04:30...out there that you can add in and start out with already having some content before you even start your project.
04:37If you have access to any ArcGIS servers, you can add in map services, image services...
04:44...WCS and WMS services, as well...
04:47...and these are all through the Add Data dialog, as well.
04:52So we'll go in and actually just go and show you using raster imagery.
05:00Oh, and...so...Wrong one? Sorry.
05:04And just a side note, all our demos here today...
05:08...when we're using the imagery aspect of it, we're only using an ArcView license level.
05:13Some of the editing that Robert does on feature classes does require ArcEditor...
05:19...but all the raster functionality in this particular presentation only uses an ArcView license or higher.
05:26Greetings, everyone. Can you hear me alright? No? All right.
05:32Is this better? No? All right. I'll try to speak down a little.
05:45All right. So as Simon said, I'll be giving you the demos today...
05:50...and for the demos, we find ourselves in Portland, Oregon.
05:54And I've just started working there, and I've already played around with some of the feature data that's available, as you can see...
06:02...but now I want to investigate the raster imagery that we have.
06:06So one of the first things that you've... I'm sure you've seen before at 10 now...
06:10...it becomes very easy if I just need a background picture to add data from online.
06:16For example, I can search for Bing or other online ArcGIS Online services.
06:20I simply click the Add button to add that imagery into ArcMap.
06:25And so I also have other data that I want to look at, and so for one thing...
06:31...I see somebody has downloaded some Landsat 5 data freely available online.
06:37And I can...and I see here that my imagery comes in seven different datasets, and I can simply...
06:45...drag and drop the dataset into ArcMap, and I can see that my data shows up as black and white...
06:51...which is not really what I would expect from Landsat data, but we'll get to that in a little bit.
06:57In addition, I also have some QuickBird data, four different scenes of QuickBird.
07:03And you can see there's a certain folder structure and...with it, where I can just add my data and then...
07:12...zoom to my layer, and here I can see that this dataset shows up in color.
07:21In addition, we have some tiled data. You can see I have a lot of different datasets here.
07:29And here, too, I can simply drag and drop it into ArcMap, have ArcMap take care of the transformation on the fly for me.
07:37I can zoom to the layer, and I can see this dataset too shows up in color.
07:43And so it's really kind of easy to use my imagery that way. I just drag and drop it in.
07:48Now we also have some net elevation data. I can drag and drop that into ArcMap, again, zoom to my layer...
07:57...and here I see that my elevation data shows up in grayscale, but even worse, it just shows up as gray.
08:04And a lot of questions that we get is, well, why is that?
08:06If I use the Identify tool, I can see that I actually have valid pixel values...
08:12...but my dataset doesn't show up; I can't really see any of the values.
08:17Simon, can you tell us a little bit of why that is?
08:20Sure, Robert.
08:29So as Robert showed you there, we have what we call the Raster Properties dialog...
08:34...and the dialog is a very good spot to obtain a lot of information about your raster dataset.
08:42We've ...divided this up into five sections.
08:45We have the data source, which basically just tells us what type of file it is and where it's located.
08:51We have the raster information, which tells us a lot of information about our actual pixels.
08:56There's a lot of valuable information in here, everything ranging from the number of open columns...
09:01...the number of bands, the cell size, and so on and so forth.
09:05Next we have the extent, which tells us the top, the bottom, the left, and the right...
09:10...minimum bounding extents of the raster dataset, followed by the spatial reference...
09:16...which gives us the coordinate system information, such as the projection, the date of the units, and so on.
09:23And lastly, we have the statistics.
09:27Let's go into detail about four of these properties here. We'll talk about No Data, color maps, pyramids and statistics.
09:35Let's start off with pyramids. Pyramids are used to speed up the display of your raster datasets.
09:43What we do is we create multiple resolution dataset layers from the original raster dataset...
09:50...and these are at varying resolutions.
09:54And when we zoom in to our raster dataset then, we first zoom in to the most appropriate pre-created layer...
10:02...and then we'll resample our data from there, so it's a lot like caching...
10:06...except caching is only set to specific scales, whereas we will then resample it back to the exact scale that we were requesting.
10:16So just as whenever we create anything, we have to add additional storage onto our disc space.
10:25But it's not that large, it's not that much extra information we have to add.
10:31Usually, it's less than 10 percent of your disc space.
10:35And we also have the ability to compress our data now at ArcGIS 10.
10:39This is a new feature we've added.
10:41And if you compress your pyramids with JPEG compression, your pyramids will be very, very small.
10:48Now I mention the word "resampling" a couple times.
10:51When we create pyramids and then you do any analysis back on your data, don't worry.
10:57We do not use your pyramids to do any analysis. We'll always go back to the raw pixel data values.
11:07Next let's talk about statistics.
11:10Statistics are used to better display your raster dataset...
11:15...and they can be used for things such as contrast stretching, classifying data, and color correction.
11:22I believe this is the problem that Robert was having.
11:26We have this image on the left side there, which shows up mainly dark and very difficult to see.
11:33Well, the image on your right there has statistics calculated and in addition is using a contrast stretch...
11:41...so we can better see the differentiation between the pixel values.
11:45And when we calculate statistics, what we're doing ...
11:48...is we calculate the minimum, the maximum, the mean and standard deviation for each band so that...
11:54... we can then use our different contrast stretches to properly stretch our data.
12:01No data is used to tag pixels or cells that have unknown information or no information available.
12:10A lot of times, people use the value of 0 and "no data" synonymously.
12:16They are not always the same.
12:19Zero is a valid pixel value, but "no data" simply means we don't know what's there.
12:26Now the confusion usually comes about because traditionally when we've stored our No Data value in a file system...
12:32...we had to use a pixel placeholder value to store a No Data.
12:37So for instance, grids tend to use negative 9999 and a lot of other formats tend to use 0.
12:45And this is when 0 and No Data became one and the same, even though they're not.
12:50Well, when we store data in ArcSDE or a file geodatabase, we store a No Data value as a bit mask.
12:57So hopefully we get rid of this notion that 0 is equal to no data, because they are not.
13:04Now, there's a lot of uses for No Data. One of the uses is that No Data does not play into your statistics calculation.
13:14So we see here, I highlighted in pink, those are all my values of no data.
13:20If I've tagged them properly as No Data and I calculate my statistics, it ignores all those values.
13:26If I had those background values tagged as 0, then it would highly skew my statistics results...
13:34...and my image would probably be a lot darker.
13:38Color maps are used to constantly open and display your raster dataset with the same colors every time you open them up...
13:45...in ArcGIS or any other program that can recognize color map files.
13:51Color maps store what a lot of people call a pseudo color table.
13:56And the way this works is, each unique value is associated with a red, green, and blue value.
14:03So in my example here, a value of 1 is equal to 255 red, 255 green, and 0 blue, which is also known as the color yellow.
14:15And this is done for each of my values.
14:18So that way when I open up my raster dataset next time, it'll show up with these colors.
14:24New at ArcGIS 10, you're now able to create a custom CLR file.
14:29A CLR file is an external color map file for some formats.
14:34And what with that, we can create our CLR file using the unique values renderer...
14:40...so this is existing UI but we've added additional functionality on there.
14:46And then we can persist our CLR file using the Add Color Map tool.
14:51Once again, we took an existing tool, but we've extended it.
14:57So let's go ahead and look at some raster dataset properties.
15:01Once again, just keep in mind that we are using... Did I do it the wrong way again?
15:06Once again, keep in mind, we are only using an ArcView license level.
15:10All right, so Simon told us a little bit about the dataset properties, so let's look at them.
15:16I can simply right-click on my data and to Properties.
15:18And here I can see a lot of information about my data, such as the number of bands, the size...
15:26...the pixel type and pixel depth, if I have permits and color maps, if it's compressed.
15:31I can see my spatial extent, my spatial reference.
15:34And I note here that I do not have any statistics calculated for it.
15:38So how do I do this?
15:39I can either click here to build statistics or right-click here and calculate statistics.
15:47Both will bring up the same geoprocessing dialog. I'll just accept the defaults.
15:52It calculates now at 10 the statistics in the background.
15:57And now I can start seeing my data the way that it's meant to be with this proper stretch.
16:04So Simon, how else can I display and render this data in ArcGIS 10?
16:13Thanks, Robert. So as Robert mentioned, the next section, we'll be talking about displaying raster data.
16:19And when we talk about displaying raster data, we usually talk about rendering and renderers.
16:26As well, in this section we'll talk about the Image Analyst window.
16:31The Image Analyst window is one of those new dockable tool...tool windows in ArcGIS 10 that we've added in...
16:41...and we'll go over that. It's a really cool window.
16:43Hopefully a lot of you will end up using it.
16:47So let's start off with the stretched renderer.
16:49The stretched renderer is often used for satellite imagery, elevation and aerial imagery, and it's used by default...
16:57...whenever you bring in a raster dataset that has a single band and more than 25 unique values.
17:06And the way this renderer works is it takes all your values, for instance, in my particular case...
17:13...I have pixel values from 0 to 255...
17:17...and it stretches it along your color ramp that you choose, and my color ramp is black to white.
17:23So therefore, a value of 0 will be displayed as white...sorry, as black.
17:28A value of 255 will be displayed as white...
17:32...and all the values in between will be stretched along the color ramp.
17:38Well, they can be stretched along the color ramp evenly, or we can use what we call contrast stretches...
17:45...in order to skew the histogram a little bit.
17:49And when we skew the histogram, for instance, on the left side of your screen, we see a raster dataset...
17:57...and it's simply just displayed with a regular no-stretch, no-contrast stretch.
18:04So it doesn't look too bad; you can see what's...you can see that you've got a main road down the middle and...
18:10...lot of green spaces and a lot of buildings.
18:13Well, if we apply a contrast stretch and we stretch out our values slightly differently based on some mathematical algorithms...
18:22...we get the image on your right, and you can see that it's a lot brighter.
18:25You can see a little bit more, in terms of definition, you can see that there's probably...
18:33...what looks like a football field in the bottom right there, and so on and so forth. So we see a lot more detail.
18:39So contrast stretches just help you display your raster dataset so you can see a lot more detail.
18:49Along with the stretch renderer, we've added in a couple new functionalities... at ArcGIS 10.
18:53We've added the percent clip stretch, so this is one of those contrast stretches I was referring to.
19:00And we've added in advanced labeling, as well.
19:03We'll start with percent clip.
19:05The way percent clip works is you specify a lower and an upper percentage of data to clip off.
19:13So let's say, for instance, I want to clip off the bottom 2 percent of my data and the top 5 percent of my data.
19:19So we basically get rid of our outliers on the edges of our histogram.
19:25And then we start our scale of 0 to 255, a little bit of a more narrow histogram.
19:34And therefore, like I said, we just get rid of all the values on the edges of our curve.
19:40That probably wouldn't have made too much of a difference, but now that we're stretching our data out in a smaller scale...
19:46...we now have a lot more detail that we can see.
19:51As well, we have advanced labeling.
19:53This was something that the cartographers were looking for for many releases now.
19:58So instead of simply having our stretch renderer with a top...a minimum value and a maximum value...
20:05...we've added the ability to add in different class breaks along the color rim.
20:12So therefore we can see that a value of yellow is very close to 2,317.
20:19So you have a little bit more idea of what the values of your various colors mean.
20:27Next, we'll talk about the RGB renderer, or the red, green, blue composite renderer.
20:32This is often used for satellite and aerial imagery, and this is the default renderer...
20:39...whenever you have a raster dataset with more than three bands.
20:43And the way this works is, each bands captures a part of the electromagnetic spectrum...
20:49...and then we display each of these bands with a red, a green, and a blue color.
20:54You put them all together and you end up with your color composite.
21:01We have the unique values renderer.
21:03This is often used for land-use maps and scanned maps.
21:07This is the default renderer whenever you have a raster dataset with a single band but fewer than 25 unique values.
21:16This is also a renderer you can use on any single-band raster dataset if you so choose to.
21:23The way the unique values renderer works is, by default...
21:28...it takes all of your values and then it displays it with a color from the color ramp.
21:34And by default, it's just a random color ramp.
21:37But you can go ahead and change all of these values if you wish.
21:42So this is sort of what the unique values renderer dialog looks like, and you can see at the bottom there...
21:49...we have a new button there, a new button drop-down called Color Map.
21:54And this is where we would import and export in a color ramp, or sorry, color map.
22:03Speaking of color maps, the color map renderer, as we've talked about earlier, uses a preset color, color ramp table...
22:13...to show your raster dataset with the prechosen colors each and every time you load it into ArcGIS.
22:19Color maps are often used for land-use and soils maps so that they can be displayed consistently.
22:26And lastly, we have the...the classified renderer.
22:29The classified renderer is used to group ranges of pixel values into a single color...
22:36...and into...many classes.
22:40For instance, we have here values from 0 to 500 being displayed with a light yellow...
22:46...501 to 900 displayed with a light orange, and so on and so forth.
22:51And this, there's various uses for this.
22:53A lot of people like to group their elevation layers together or their elevations together...
22:58...so instead of seeing a wide range of color ramps, you can choose different step intervals to show your data with.
23:07And this is never a default renderer but you can use it for any single-band raster dataset that you may have available.
23:15And lastly, let's talk about the Image Analysis window.
23:19The Image Analysis window has been added to ArcGIS 10.
23:24It's, it's basically a window that contains a lot of display and processing features that you could access with a...
23:32...single click, so most of the functionality is already existed in ArcGIS 9.3.1 and previous...
23:41...but with this window, instead of having to dig into the...UI, most of these are available right there...
23:50...and you can access them within one...
23:52...one second rather than digging through the user interface and trying to search for where they are.
23:58In fact, there are demos this year are about about, I'd say, 30 percent shorter because we're using this window...
24:05...rather than digging through the UI to go look for the particular button or function.
24:10And this Image Analysis window is broken up into the, as I mentioned, display and the processing.
24:17Within the Display tab, which is what we'll talk about here at first, and processing we'll talk about later...
24:22...we have everything from the Effects toolbar available, everything from brightness, contrast, transparency...
24:29...we have a lot of the symbology tools, such as Gamma, the various contrast stretches and DRA...
24:36...which is dynamic range adjustment. We also have the ability to choose your resampling method.
24:42And this is also where you accelerate your raster.
24:45This was shown in the plenary how you make your imagery scroll faster, which we'll talk about slightly more in today's demo...
24:52...which Robert will be giving right now.
24:58Thank you, Simon.
25:00So, I've calculated statistics on my elevation data, so let's see how else I can visualize this data.
25:07In the table of contents, I can simply change the color ramp by left-clicking on it and choosing a different color ramp.
25:15But I can also go to the layer properties and the Symbology tab, and here we see mostly what we've seen in previous years.
25:24So I can change my stretch type very easily to minimum/maximum and other things.
25:30A new thing is that we have this advanced labeling option.
25:36I can set my number of intervals, change my color ramp, and give it a custom color.
25:46So this is a way for me to emphasize a specific color range and cartographically display my data quite differently, such as that.
26:02In addition, note here that in the table of contents, now I have elevation values corresponding to my different colors.
26:12So in addition to this new advanced labeling, I can also use the classify renderer.
26:17If I want to, say, display my data in something like low, medium, and high.
26:25So it becomes very easy to display my data in various ways.
26:31Let's see how, what else I can do.
26:34So I have my Landsat data here, and I have this new Image Analysis window.
26:40To access it, you simply go to Windows and Image Analysis Window.
26:45In my case, I've already docked it on top of the table of contents, and here you can see...
26:49...I can easily change the contrast and brightness, I can change my stretch...
26:57...and so it becomes very easy for me to interact with my data.
27:01Now Simon earlier alluded to color maps, and in my department, we've had somebody create a land cover classification.
27:12And whenever we use this data... Let me zoom in here a little bit.
27:17Whenever we use this data, because it has less than 25 unique values, it uses by default the unique values renderer.
27:24And...every time we load it, the color comes out different.
27:27So a workaround in the past has been to save a layer file with it, and then whenever we use the layer file...
27:33...we see the colors that we would expect.
27:36In my case, water should be blue; bare soil should be brown; vegetation, green; and so on.
27:42So now at 10, we have a very easy way to persist this.
27:46I simply go to the layer properties, and I...we can see the unique values renderer is used.
27:51I can click on Color Map, Export Color Map, and then, I can simply save my color map file.
28:02Now that I'm done saving this file, I need to persist this to my dataset.
28:07To do this, I'm going to search for our color map tools.
28:13And we see that we have two different color map tools, Add Color Map and Delete Color Map.
28:18I want to add a color map. I'm going to ask the dataset that I want to add this color map to, and just quickly...
28:27...I want to show that in the dataset properties, the color map is currently absent.
28:34I also need to add my color map file that I just saved, and I click OK.
28:43Now let me remove these files again, now simply add the...classification file...
28:52...and now we can see that the colors are applied the way that I would expect.
28:56The other benefit of saving the color map file is that...
28:59...I can apply the same color map to multiple datasets that have the exact same classification.
29:06So Simon, how else can I display and use my data?
29:15Well, the next thing we want to talk about is rendering your mosaic dataset.
29:19As we mentioned, the mosaic dataset is a new raster data model that we've added to ArcGIS 10...
29:26...stored like a catalog, works like a raster dataset, kind of the best of both worlds.
29:33So we'll start out and talk about the way this is shown on your screen.
29:37When you add this in by default, you first see these green lines surrounding each of your raster datasets.
29:45Each of these lines are a footprint, so it's a lot like a raster catalog.
29:49The raster catalog also had this idea of footprints.
29:52And each of these footprints just has a box around the minimum boundary rectangle of your raster dataset.
30:00Well, otherwise, other than being stored like a catalog and having these footprints...
30:06...it's a lot like a raster dataset in terms of the actual rendering of the pixels.
30:10We simply have our data there, and then hopefully it shows up; if not, you'll...
30:18...there's other tools to help you better display your data, such as building overviews.
30:23While assuming that our pictures do show up properly, what we have is...
30:29...we also have the idea of the level of detail within the mosaic dataset.
30:36What level of detail is, it's a lot like scale dependency.
30:40So whenever we're zoomed out at a scale such as 1 to 100,000, we can see our low-resolution imagery.
30:50And then we, when we zoom in...
30:53...and assuming you have more than one resolution available in your mosaic dataset...
30:57...and you zoom in at a scale of, say, 1 to 25,000, you can then see high-resolution imagery.
31:06So if we manage and create our mosaic dataset properly...
31:13...we can use this to show your imagery with varying levels of scale rather than having ArcMap do that for you.
31:20And this way, it's stored within the mosaic dataset and therefore, every time you transfer to a new map document...
31:28...this is already saved within there.
31:30As all...as mentioned, we have these things called overviews.
31:33Overviews are a lot like pyramids.
31:35We pre-create different layers of varying resolution, and what this allows us to do is...
31:41...it allows us to view our data at any scale, and it also allows us to view our different levels of scale a lot quicker.
31:54Another new thing within mosaic datasets is mosaic methods.
31:58What mosaic methods do is, once again, it's whenever you have data that overlaps on top of each other...
32:05...you have to figure out which one is going to be displayed.
32:09And mosaic methods help us define the display order whenever we have overlapping rasters.
32:16So we'll start out with one of the easier mosaic methods, which we call By Attribute, which is over here.
32:23And the way this works is, we take one of your attribute fields, for instance, cloud cover...
32:30...and then we can display whichever raster dataset has the least amount of cloud cover.
32:35Of course, you'd have to assume that you're specifying that you're going from lowest to highest.
32:40You could also go the other way around, so it's your choice.
32:43So, and, with... so we'll look through the attribute fields, and whenever there's a conflict of overlap...
32:49...we'll always choose the lower cloud coverage.
32:53So in this case, the green footprint would be the one on top, followed by the purple and then finally the yellow one.
33:02We also have the... most northwest, and the way this works is, we find the cell center of each of your raster footprints...
33:14...and then we...whichever is closest to the northwest corner will be the one displayed on top.
33:21In this case, my yellow footprint is the closest to the northwest corner, so that will be displayed on top...
33:28...followed by green, followed by purple.
33:31Next, let's look at Closest to Center.
33:34Closest to Center, once again we're using the center point of your footprints, and the way it works is...
33:41...whatever the display center is closest to your footprint center, those are the ones shown.
33:50So my screen here or my display is outlined in the black dotted line, and the center of my screen is shown by this X over here.
34:00And therefore, the closest center to my X would be my yellow one, followed by my green, followed by purple...
34:07...so that's the order that these would be displayed in terms of what's on top.
34:14Next, we have Closest to Nadir. The center of your footprint is not always the nadir point on your footprint...
34:23...especially in oblique imagery; this could be _____ skewed.
34:26So we find the nadir point of your imagery, assuming that your metadata had this information...
34:32...and then we find which...which nadir point is closest to your display center.
34:40Once again, the display center is an X, and your nadir point is the dot, and therefore, in this case, green, or sorry...
34:49...yellow would be shown on top, followed by purple, followed by green.
34:55One thing that we have to mention for Closest to Center and Closest to Nadir...
34:59...whenever you change your display screen or the extent of your display, the way that these are displayed can change.
35:07So for instance, we'll go back to Closest to Center here.
35:11I zoomed into a different spot within my mosaic dataset here, as shown by the dotted box.
35:18When I change my display extent, Closest to Center and Closest to Nadir has now a different center point.
35:26So now my center point would be closest to my purple footprint, so that would be displayed on top...
35:32...followed by the yellow, followed by the green. And lastly we have Closest to Viewpoint.
35:37Closest to Viewpoint, once again, we use the nadir spot within your footprint or your image.
35:44And we can manually choose the viewpoint.
35:48So we're not using the center of the screen anymore for viewpoint; we're choosing a predefined location of view...
35:55...and therefore once again, we go, which is the closest nadir point to your viewpoint, and that's how display them on top.
36:02It goes from yellow to green to purple.
36:05So let's go ahead and discuss some of our mosaic dataset demos here.
36:13As mentioned, all the...raster functionality we are showing in this particular demo only uses an ArcView license.
36:23Robert will be doing some editing on vector data; that requires an ArcEditor license.
36:28All right. Thank you, Simon.
36:30So one of my coworkers has created one of these new things called a mosaic dataset.
36:34And we find it here in my file geodatabase.
36:37I can simply add it to ArcMap, and now I can see that this thing on the fly creates a composite of my Landsat data...
36:44...so now my Landsat data shows up in RGB color rather than grayscale.
36:51So now I can zoom in, and as I zoom in and continue to zoom in, I start seeing the scale dependency in my imagery.
37:01So at first I saw my Landsat data; now I'm looking at my QuickBird data.
37:05I can zoom in further, and here, I can see some of my tiles that are overstretched.
37:11So I can...simply change my stretch type to Min/Max to make it look nice.
37:18As I zoom in further, I can see I have more data underneath with higher resolution.
37:24So let's zoom out a little bit and look at this thing called the mosaic dataset a little bit more.
37:32In my table of contents, I can see that the mosaic dataset is a composite layer.
37:37So we have my group layer right here, and then a boundary layer, a footprint layer, and my image layer.
37:43My boundary is a feature containing all the imagery that I have in this mosaic dataset.
37:51My footprints is a feature showing me the extent of each individual tile that is contained within my mosaic dataset.
37:58And so you can see here that I have a lot of different data making up this scene.
38:05If I right-click on the footprint, I can open the attribute table.
38:09This attribute table has a lot of information, so we can see my data here...
38:15...we can see it's populated with a group name and a product; my center x and y...
38:20...which is used for the mosaic method that Simon talked about...
38:24...we have my sensor name, when my data was acquired, and a lot of other information.
38:31And my friend has added this Year field to help me figure out exactly what year my imagery is from.
38:43So I came across a point where I looked at my feature...where I need to make some edits.
38:52So in this case here, we can see that I look at my 2001 imagery and my road map network neatly lines up with the roads on my imagery.
39:02Now I'm going to go to this mosaic method through the image properties...
39:07...and I'm going to choose the By Attribute mosaic method and, in my case, the year.
39:14So now as I look at my year 2005, I can see that there's a new subdivision and I need to update my roads.
39:23Now rather than ...having to go through all my files in this to figure out what exactly are the files I need to use...
39:30...I simply use the mosaic dataset and it does all the managing for me.
39:34So I can zoom in to my data. I'm going to start an edit session here for my streets data.
39:51Now before I'm going to start an edit session, I want to point out...or as I, as I start editing, really...the...
39:58...in the past, we would edit, and then once we get to the edge of our editing, we would have to pan...
40:08...there you go...and then continue editing.
40:12Well, this has changed at 10. I can use the Image Analysis window to accelerate my raster.
40:23And now we have several ways that we can take advantage of this technology.
40:28So for one, as I pan, now you can see, I have a seamless pan experience, and I can continue my editing.
40:37But it goes further than that. I can also use the hot keys on my keyboard.
40:43In my case, the Q key, which allows me to now roam through my image and digitize on top of my image...
40:53...as it moves beyond my data.
40:57And so now this makes it very easy for me to move around and digitize my data.
41:04Back to you, Simon.
41:10Thank you, Robert. So the next section we'll talk about deals with processing raster data...
41:16...and we have a lot of different tools even within out-of-the-box desktop core raster in order to deal with your imagery.
41:24We have everything from combining bands, clipping data, mosaicking, pan sharpening, orthorectifying...
41:30...and this is just a select list, that we have a lot, lot more tools than that.
41:36So let's start out with combining bands.
41:38Combining bands takes many images, whether they be single band or multiple band.
41:44Oftentimes, they're single-band images. We'll take a bunch of those and put them into a single, multiple-band raster dataset.
41:52And the reason we do this is, first of all, assuming that this is the data all lining up on the same spot...
42:00...instead of having to manage three or seven different layers, we can only manage, we only have to manage one file.
42:06In addition, since most of the times, our sensor data comes in, for instance, Landsat has seven bands...
42:13...and your QuickBirds have four bands...you put them all together in one raster dataset.
42:18We're only managing one file, as mentioned, but we also have the ability to now display your imagery in color.
42:25If they're all stored as single bands, they're only displayed as black and white, as we discussed in our default renderers.
42:32We have the ability to clip our data.
42:34So clipping our data would take a small portion of your study area and simply subset or clip up that portion of your file.
42:44When we clip your data, traditionally we tended to use geoprocessing tools such as the Clip tool.
42:52We had the Export Data dialog window, but now what we have, as I mentioned...
42:58...we have this processing panel within our Image Analysis window...
43:01...and we're now able to clip on the fly using the Image Analysis window.
43:07By the way, I forgot to mention...
43:09...when we use composite bands, that button is also available on your Image Analysis window, as well.
43:15In fact, there's a continuing trend here, even with mosaicking.
43:20Mosaicking, we take two or more adjacent and overlapping raster datasets, and we can put them together into one file.
43:29A lot of geoprocessing tools that are still valid and were available before, such as Workspace to Raster Dataset...
43:36...Raster Catalog to... Raster... Raster Catalog to Raster Dataset, were available and still are available...
43:43...but now we have the ability to mosaic on the fly.
43:46We have the ability to just click the Mosaic button on our Image Analysis window.
43:52And we also have the mosaic dataset, data model, which is kind of like a virtual mosaic since we can create them fairly quickly.
44:03Pan sharpening is when we take a low-resolution RGB image...
44:08...and fuse it together with a high-resolution panchromatic image...
44:11...and the outcome is a high-resolution color image.
44:17Once again, geoprocessing tools have been available in the past and still are available.
44:23The Raster Symbology tab always let us do this in the past...
44:26...and now we have the button on our Image Analysis window.
44:29So we can see that Image Analysis window takes...a lot of the functionality we already had...
44:36...but instead of having to dig through the toolbox or the different symbology tabs and whatnot...
44:43...they're available to you on that window with a single click.
44:46As well, they're done on the fly, which Robert will show you later and as mentioned...
44:51...our demos are easily 30 percent shorter now because we're no longer having to persist it out on disc.
44:59And lastly, we'll talk about orthorectify. We have the ability to display our imagery with more accuracy...
45:06...assuming that we have a sensor model available and an elevation source.
45:12And usually that elevation source is a DEM and your sensor model are rational polynomial coefficients.
45:19Once again, not a new feature, per se.
45:22Always available within our geoprocessing tools, always available within our raster display tab...
45:29...and now available with our Image Analysis window.
45:33Speaking of, this is the processing panel. It's at the bottom of your Image Analysis window.
45:40As we saw, we have a lot of different tools that I've mentioned available and a lot more.
45:46And all these tools will process on the fly, all except for one.
45:51The Export Data will actually bring up the Export Data dialog.
45:56But all the other tools on here will simply process your data on the fly within a single...
46:00...click so therefore you get your done, your work done very, very quickly.
46:06So let's just go ahead and see how fast this can now be done.
46:12All right, then. Thank you, Simon. So this is going to be my last demo.
46:17And for this demo, we find ourselves in...downtown Portland, and here you can see I have several feature layers.
46:26I have my tax lot information in the gray features.
46:31I have building footprints, and then a study boundary that was given to me when I'm supposed to do my analysis.
46:37Now my task is to compare the building footprints with footprints that I can identify on new imagery that we've acquired...
46:46...and compare them to see where we need to update our data or where we maybe have to go out into the field...
46:52...to figure out if we need to update the tax information for the tax lot.
46:58And so we've received some GOI data, and here you can see that I have several different datasets, each representing a band.
47:06I can simply drag and drop them into ArcMap, and here you can see I have my blue band, my green band...
47:15...my red band, my near-infrared band, and my panchromatic band.
47:20So now I need to prepare this data so that...that I can properly use it.
47:25So the first thing I'm going to do is I'm going to make a selection of my color bands.
47:31I'm going to click the Composite Bands button.
47:34This creates a new layer, which applies to composite on the fly...
47:38...which allows me to visualize my data in color very easily.
47:42I'm going to remove the individual bands 'cause I'm done with them.
47:48Next, I'm going to easily apply the sharpen filter on my panchromatic image to make it look a little bit sharper...
47:56...which helps me later on, and then I can remove that. Let me change the order here a little bit.
48:05So now as I zoom in a little bit, I can go right here.
48:14We will see the higher-resolution color image as well as my lower-resolution...
48:20...my higher-resolution panchromatic image as well as my lower-resolution color image.
48:27And so now, I can simply pan sharpen them together to give me a higher resolution, crisp image, the way that I would expect.
48:36Now let me reorder this so I can see my features.
48:41And now we can start identifying all features.
48:44But before we do, I want to set up the imagery a little bit nicer so I can better identify these features.
48:50So I'm going to turn on DRA, I'm going to change my stretch type to Present Clip...
48:57...and then I can also change my gamma a little bit so I can see my features a little bit easier.
49:05Next I'm going to accelerate my data, and now I'm going to turn on my points of interest.
49:14I've already started identifying some of them.
49:19For example, here you can see there's a shed that we don't have any footprints for.
49:25Next, I'm simply going to start my editing and select To Create Points.
49:35So now, I can look around and try to identify features for possible points of interest that I'm interested in.
49:44So now we have several ways to roam around. I can, as usual, pan.
49:49I can use the Q key that I've shown you earlier, but in my case, I want to use my arrow keys.
49:55So I can click my arrow keys, and you can see it goes pretty quickly.
50:00And so in addition, I'm going to hold down the Shift key, and now...
50:04...as I roam around, I can simply click wherever I find points of interest...
50:12...like here, we have two buildings.
50:14And right now you don't see this point, so as I stop, and I have to wait for the rendering for a second...
50:20...here you can see how I digitize my points even while I'm roaming.
50:27So now I just look through my imagery to try to...to find these points of interest, in my case.
50:38So now that I'm done, these points are more than just...graphics on my display.
50:44These are actual features in my dataset.
50:47So for example, I can now create a simple spatial query against my tax lot information.
50:56I go into Selection by Attribute, and when I select my lots that contain my ...the points...
51:05...the features that I've just edited.
51:08And now if I go to the attribute table off my tax lots, I can get all the information off my tax lots...
51:13...including the owner, the address, the zoning, and everything else.
51:22And so now I can easily create driving directions to these places so I can do my ground truthing and everything else that I need to do.
51:29And so you've seen how easy it was for me to set up my data and start using it right away...
51:34...rather than running several geoprocessing tools to get the output that I needed.
51:39Back to you, Simon.
51:44So as we saw, there's...ArcGIS 10 was, not only for imagery and raster but throughout the entire Desktop product...
51:53...about doing your work faster and helping you achieve your tasks.
51:58We've listened to a lot of the feedback that you, the users, have had, whether it be through the forums...
52:05...comments you make here at the User Conference, comments you make down at the showcase booths...
52:10...and we try to incorporate a lot of the ideas that you have.
52:13So here's the summary of what we've added to ArcGIS 10. Most of these were user driven.
52:21The first one was one of our biggest changes that we've made, but hopefully you don't notice too much.
52:28What we've done is we've added in a brand-new format library, used for all our data, raster data formats now.
52:35Now I say, hopefully you don't notice that we've done this change because...
52:38...hopefully your data still works the exact same way that it used to.
52:42The reason we added in the new raster format library is to get rid of the limitations that we had with our old format library...
52:50...add in new data formats, such as the ability to display a big TIFF.
52:55A big TIFF is a geoTIFF that is larger than 4 gigabytes in size.
53:01We've made a big TIFFs as large as 75 gigabytes or so. I'm not...yeah.
53:08So Robert's made one at least 75 or more, and so on and so forth.
53:11And we've added in other data formats, as well, such as the BAG format...
53:17...which I know a lot of the nautical people are very happy with...
53:19...and we've added in ISIS, and so much more, as well.
53:24As mentioned, we have over 65 different formats available to read at ArcGIS natively.
53:31Of course, you can add in your own custom formats still.
53:34We've also added in the ability to write out four new formats.
53:38Not new formats, per se, but new writing formats for us.
53:42We've added in the ability to write out a BIL, a BIP, a BSQ, and also an NVDAT file.
53:52We've added in the new mosaic dataset data model, as we've shown.
53:57Hopefully, you'll try and use this and implement this within your work if you use a lot of imagery.
54:04In fact, this is a big focus for us here at the User Conference, and there's a lot of different sessions dealing with mosaic dataset.
54:12I'll go over a session slide with you after what's new.
54:16We've added in the image analysis window. As Robert showed you, you did your work very quickly.
54:22You didn't have to persist it on disks.
54:24So you simply do all the processes that you need to do, and then once you're ready...
54:30...Now you can go ahead and persist it out on disk rather than having to do that several times.
54:36We've added in the ability to do advanced labeling, which a lot of the cartographic people are very happy with.
54:42And we've added in the ability to do a couple of new features at color correction.
54:48Not only did we add in new color balancing methods for the raster catalog...
54:54...we've added in the ability to color correct your mosaic datasets as well.
54:58So those new mosaic datasets can be color corrected as well.
55:03Keep in mind, we only do color correction on raster catalogs and mosaic datasets.
55:11We do not color correct single raster datasets.
55:16We've added in raster functions.
55:17These are all the on-the-fly processing tasks that Robert showed you.
55:23These are all done with what we call raster functions.
55:27So they're hidden behind the scenes, and they can also be exposed, but this is how we do them on the fly.
55:34We have the raster options menu.
55:38This is not new, although it's found under a new spot now. At ArcGIS 10, it's under Customize Options.
55:44And the tab itself is not new. We've always had it...
55:48...but we've added in the ability to do so many more parameters and properties...
55:54...that you could set by default before you start any of your raster work.
55:59This has been highly user driven.
56:01A lot of the users said, Well, I don't like standard deviation.
56:04I want to start my raster dataset being displayed with the min/max renderer or the histogram equalizer, and so on and so forth.
56:12And I want to use bilinear interpolation since I deal with a lot of satellite imagery.
56:18So a lot of these things that you've asked for are here now in the Raster Options tab...
56:25...so that you can start your work and hopefully do your work a lot quicker.
56:30We've added in the ability for a lot of new and enhanced geoprocessing functionality.
56:38We've added in a new toolset for the mosaic dataset.
56:41There are 16 tools in here to help you create, edit, and manage your mosaic datasets.
56:47We've also added in four additional geoprocessing tools for your raster datasets.
56:53We've added in Split Raster, Raster to DTED, Build Pyramids and Statistics, and Make Mosaic Layer.
57:03We've improved two of our previously existing tools.
57:06Mosaic to New Raster used to be a script tool. Now we've turned it into a full-fledged system tool.
57:14And as Robert showed you, we've improved the Add Color Map tool.
57:20So we can not only add in CLR files now, another thing we can add in are ACP Adobe color table files as well.
57:29In the Environment setting for the geoprocessing tools, we've added in the ability to compress our pyramids.
57:35So now we can create pyramids that are smaller.
57:38And we've also added in the ability to do more TIFF compressions.
57:42In the past, we simply LZW, LZ77.
57:46Now we have the ability to do CCITT, PAC bit, so on and so forth.
57:53So we have a lot of development sessions here about raster and imagery.
57:59You're currently attending Using Imagery and Raster Data.
58:03Hopefully, you know that now.
58:04And we have many other sessions which will help you with your raster imagery needs.
58:13One of the main sessions that you'll probably want to attend after this one, if you're still interested in imagery...
58:19...is Managing Imagery in Raster Data.
58:22So this will not only go over how to manage your raster datasets...
58:26...your raster catalogs, it'll also tell you a lot more about this mosaic dataset.
58:30It'll tell you when you would use it, why you would use it, and how you create it and how you edit it.
58:37Along the same lines, we have Working with Sensor and Image Data.
58:41So once again, this deals with the mosaic dataset and managing data, but this has more of a focus on sensor data.
58:47So if you get a lot of sensor data, QuickBird, Landsat, IKONOS, so on and so forth...
58:53...you'll want to attend that session.
58:55So both of these sessions are actually being offered right after this one.
59:00Managing will be taking place in this room, and Working with Sensor Data will take place in room 3.
59:06If you want to know more about what's new in ArcGIS 10 with raster...
59:11...there's three different sessions you can attend to go and see that.
59:15And if you're more interested in the server side aspect, we have Working with Image Services in ArcGIS Server.
59:22And these are all technical workshops up in green.
59:26We have four demo theaters also available for you.
59:29Once again, on the server side, we have Building Web Applications for Image Services.
59:33That takes place today in the morning at 11 o'clock down at the Server Island.
59:39And the next three demo theaters we have take place on the Geodatabase Island.
59:45We have Georeferencing Raster Data, which takes place this afternoon...
59:48...Creating Mosaic Datasets, which takes place tomorrow morning...
59:53...and Using Image Analysis Window, which takes place Thursday afternoon, which Robert will show you.
1:00:01We also have this thing called Imagery at UC 2010.
1:00:05So this is...we have a lot of keynote speakers, case studies, moderated paper sessions, and so on.
1:00:13Most of this takes place in the Omni Ballroom. That's at the Omni Hotel across the street.
1:00:19And we also have the Exhibit Hall and Demo Theaters.
1:00:22The Exhibit Hall will have people within our staff...
1:00:26...and also all our third-party business partners will be right around that Imagery booth.
1:00:31So you'll want to go to the Imagery booth if you're highly interested in imagery, not only for ArcGIS...
1:00:37...but also our third-party business partners.
1:00:42So we have two links that we'd like to give you, the new Imagery Resource Center.
1:00:48So this has been updated for ArcGIS 10.
1:00:51So for any and all of your imagery needs, hopefully you can go here and find the information that you want.
1:00:58We also have the Imagery blog available. This can be accessed through the resource center...
1:01:02...but I thought I'd highlight it anyways.
1:01:05The blog offers a weekly and, sometimes, more than once a week.
1:01:11It offers just some supplemental information that we'd like to highlight...
1:01:16...and sometimes we simply give out announcements if there's a big announcement coming out.
1:01:23So we'll go ahead now and open the floor to any questions we have. We have about 15 minutes of questions.
1:01:28So let's start out. In the black, there in the aisle?
1:01:31[Inaudible audience question]
1:01:45You know anything about that? Land-use land cover classifications?
1:01:53Unfortunately, we had networking problems over at Redlands, so I didn't see the entire plenary.
1:02:00It cut out on us a lot, so I'm not sure exactly what particular portion you're referring to.
1:02:06But please come up and we'll talk about that in more detail.
1:02:09Unfortunately, like I said, most of the plenary, especially the imagery part, was cut out from our end of the viewing spectrum.
1:02:17I wasn't here yesterday at the plenary. There in green?
1:02:21[Inaudible audience question]
1:02:24Oh, oh, thank you.
1:02:26[Inaudible audience question]
1:02:39So...so the question is, how do you persist that color map with the image?
1:02:43And there is a geoprocessing tool called Add Color Map.
1:02:47You want to show them?
1:02:49Yes. And so you can simply search for Color Map, and then you'll open the geoprocessing tool...
1:02:56...and then you add the image up here, and then on the bottom here, you point to the file that you just saved.
1:03:05And then it persists it to the dataset.
1:03:09All right. In orange?
1:03:11[Inaudible audience question]
1:03:31Okay, so the question deals with bathymetry data, and it's very large.
1:03:37Do you know which format your particular data is in?
1:03:41[Inaudible audience response]
1:03:46Okay. It's a grid? Yeah, okay, so it's grid.
1:03:49[Inaudible audience response]
1:03:52Okay. So grids should be able to handle large amounts of data...
1:03:58...so we'll probably need to talk about that on a case-by-case basis.
1:04:04It's something that should work. It might be a bug, it might be the data.
1:04:07We're not sure. We'll have to talk about it a little bit more in detail.
1:04:12Are you hitting a 65,536 limit?
1:04:17[Inaudible audience response]
1:04:18Okay. Okay.
1:04:19I can go to 9999999. Right.
1:04:22Okay, sorry.
1:04:23You can set it high, but then it takes a while to create it.
1:04:26[Inaudible audience response]
1:04:28Okay. Okay, okay. We'll have to look into that.
1:04:34Definitely. We'll look into that. Please come see us afterwards. In the blue there?
1:04:38[Inaudible audience question]
1:05:00So, so the question deals with, they've been using imagery at 9.3.1, displayed fine.
1:05:08They bring it into ArcGIS 10 and images are now way off to the other side of the screen.
1:05:13It sounds like there's a lot of, this most likely deals with projections and extents and...
1:05:19Do we still? Right.
1:05:22[Inaudible audience question]
1:05:23Do we still have bugs with that? I thought we fixed most of those.
1:05:27If you can give us the data, we need to look at it.
1:05:30That was definitely one of the issues we had to look for in ArcGIS 10, and as we mentioned...
1:05:35...we hope your data still works fine, but there might have been some formats, some projections that aren't quite working...
1:05:41...especially...do you know which projection you're dealing with?
1:05:45[Audience response]...State Plane.
1:05:46State Plane, so...
1:05:48[Inaudible audience question]
1:05:49Okay. Wow. Alright, we'll definitely want to talk about this one. That's a very big deal to us.
1:05:55That was one of the ones that we're definitely trying to avoid. In the white in the back there?
1:06:01[Inaudible audience question]
1:06:11So the question is...mosaic datasets. This User Conference, we're really trying to push this mosaic dataset.
1:06:19Are we going to phase out raster catalogs or raster dataset?
1:06:22The answer is definitely no, especially for raster datasets.
1:06:26If you get rid of raster datasets, you can't use the mosaic dataset since it's based off of a raster dataset.
1:06:33We're not phasing out raster catalogs. We're still supporting them.
1:06:35I have heard no word about if we will defer them, but my guess is we'll keep them.
1:06:42It'll turn into a normal thing where we don't necessarily improve upon it.
1:06:46It's still there. We'll still support it for now...until I hear otherwise. They're still available.
1:06:52It's just we've added in a lot of functionality to this mosaic dataset, which we're not able to do given the raster catalog structure.
1:07:00So this is how we're making it so we're dealing with the issues that a lot of large agencies have.
1:07:07We had to create a new data model. In the blue?
1:07:11[Inaudible audience question]
1:07:14Mosaic datasets? Mosaic datasets, are they compatible back to 9.3.1?
1:07:19The answer is no, they are not.
1:07:21It deals with the geodatabase, so since we're storing it in a 10 geodatabase...
1:07:27...we cannot back port it to a 9.3 geodatabase, at least not that we have planned on doing, but...
1:07:33[Inaudible comment]
1:07:34Right. Okay, so Robert mentioned a good point.
1:07:36If you do want to serve out your data using ArcGIS Server, your 9.3 client can view it.
1:07:43But in terms of the actual desktop product of accessing a mosaic dataset...
1:07:49...we cannot do it because it's stored in a 10.0 database. In the front?
1:07:53The boundary and footprint is...
1:07:58[Inaudible audience question]
1:08:00Yes, the boundary and footprint our polygon features.
1:08:05Okay, over there in the blue?
1:08:08[Inaudible audience question]
1:08:16Sorry, I couldn't really hear that. I just heard peak words here and there.
1:08:20[Inaudible audience question]
1:09:08Okay, so the question is, when you serve out this mosaic dataset, is it like a raster dataset, or what is it like, correct?
1:09:17[Inaudible audience question]
1:09:20So first off, just to make sure we're on the same level, to serve out the mosaic dataset...
1:09:25...there's an extension on the server that you need.
1:09:28But once you serve it, it's an image service, and so as such, it'll be like a normal image service that you consume.
1:09:36It looks like a single dataset. You still have the scale dependency.
1:09:39And in addition, there are additional tools. You can actually download some of the...like, your data...
1:09:45...if the person that serves it out allows it, and other things.
1:09:49But as you consume it, it's like a dataset.
1:09:53Right. So as we mentioned, even though it's stored like a mosaic dataset, a raster catalog...
1:10:07[Audience question] So when would you use a raster catalog?
1:10:10[Inaudible audience question]
1:10:15Right. So the question is, when would you ever use a raster catalog?
1:10:21There's a lot of drawbacks from raster catalogs and therefore, a lot of people didn't like using them.
1:10:28Well, certain people have certain situations where they do want to use this.
1:10:33It's definitely a preference, a lot of preference, especially with this new mosaic dataset.
1:10:38Some people just wanted to, as the name mentions, just catalog your data.
1:10:43Take all your datasets, throw it into the so-called raster catalog, and be able to see where these so-called footprints lie...
1:10:51...and then choose which footprints you want to actually view or sort of make maybe a subselection on them...
1:10:59...we tried to make the user functionality a lot more like a raster dataset or an image service, in this case. In the brown?
1:11:02...save it out to, then, your study area of interest, and so on and so forth.
1:11:08So there's definitely still uses for them, but...a very quick way to just display where your data...
1:11:13...like, as a catalog shows you, it's just a quick, small version of what you have available.
1:11:19[Inaudible audience response]
1:11:22Right. So what will the mosaic dataset do?
1:11:24The mosaic dataset still creates these footprints for you but adds in a lot of functionality...
1:11:30...because like you and many other users said...
1:11:32...you know what? This catalog thing, I like the way it's stored but how do I use this?
1:11:38And hopefully the mosaic dataset will be able to have more functionality for you to use, like I said...
1:11:43...like a raster dataset, just a lot more easier. I'll get you in a second up here. Oh, yeah, sorry. Alright.
1:11:50[Inaudible audience question]
1:12:06You can. Repeat the question.
1:12:07Okay, so the question is, can you use the mosaic dataset for analysis?
1:12:10And I think a lot of those questions for the mosaic dataset will be answered in the next session.
1:12:15But to get to your answer, yes, you can use it.
1:12:19There are tools to allow you to make sure you're using a specific tile that you choose, that this tile that you're looking at.
1:12:26Because you have scale dependency, you're looking at one tile, but the final resolution might be below.
1:12:31Right? And so there are ways that you can say, "Really, only use this tile. I want to do my analysis on this tile"...
1:12:37...and those kind of things.
1:12:40Yes. Right. They'll talk a little bit more about how to create it and some of those things.
1:12:46[Audience question]Do you have any experience with using a huge number of tiles?
1:12:52Do you see any performance degradation?
1:12:56We've seen, we've loaded into the mosaic dataset some like 8 million and 10 million records, and so...
1:13:06...it scales very well, especially if you have permits... or overviews, overview files.
1:13:12And the display also works very well.
1:13:14And really, at that point, it's beneficial to turn off the footprint because displaying all those vectors takes a long time...
1:13:22...kind of like if you have a huge feature class that you're trying to display.
1:13:26But the raster result is much faster.
1:13:30Okay, we'll take three more questions, and then you can either attend the next session or...
1:13:35...you can come and talk with us down at the Imagery and Raster islands.
1:13:39In the green up front? Oh, I'm sorry, I thought you...
1:13:40[Audience question]Is this PowerPoint going to be available?
1:13:43I have given my PowerPoint, I have uploaded to some server, my student assistant has taken it.
1:13:48I'm assuming it's available somehow. I just don't know how you would obtain it, but it is available.
1:13:55Over there?
1:13:56[Inaudible audience question]
1:14:10Okay, so the question deals with the new color map files, the CLR files that we create.
1:14:16As mentioned, there's a two-step process. We create the CLR and then we persist the CLR.
1:14:22When we use the Add Color Map tool to persist our CLR file, it is now persisted to that particular raster dataset.
1:14:30You can delete, move, rename, whatever you want, with your color map file.
1:14:34And in fact, your color map file, especially if you're using land-use classification...
1:14:38...can then be used for many other raster datasets.
1:14:43But, so the question is, if I edit my CLR file now, will that update my raster dataset?
1:14:49The answer is no. That Add Color Map tool is when it was persisted.
1:14:54Of course, you can change the color map or the CLR file, and then repersist it again, so on and so forth.
1:15:00Alright, last question for this particular session.
1:15:04Nobody. Alright, great. Thank you very much for attending. Please stay for the next session or just come down...
Using Imagery and Raster Data in ArcGIS
Imagery and raster data comes from various formats and services. This session teaches you how to use ArcGIS to integrate imagery and raster data into your projects. The properties of raster data including pyramids, compression, color map, resampling, as well as best method to use them will be covered. The session will also introduce the new Image Analysis window and the new mosaic dataset, which together provide a streamlined environment for managing, enhancing, and processing imagery.

Dual career couples, particularly in the research or higher education community, may find assistance with this service. Please go to www.midatlanticherc.org (NOTE: This resource is not affiliated with NSF or the Federal government.)
The following types of positions are available at NSF:
The 2012 Federal Employee Viewpoint Survey (FEVS) results reflect the opinions of permanent employees at the National Science Foundation. The FEVS is a government-wide survey conducted by the Office of Personnel Management (OPM). In April and May 2012, as part of the government-wide trend analysis effort, OPM surveyed permanent employees who were with NSF as of October 1, 2011. In order to provide all NSF employees and IPAs a voice, NSF requested OPM survey newer employees as well as temporary and rotating staff. These results will be displayed on this page when they are available.
The FEVS results inform NSF's human capital and employee engagement strategies. The 2012 results indicate an overall stable trend in most areas. NSF continues to see high positive response rates to questions regarding NSF's ability to successfully accomplish its mission. NSF employees feel strongly that they are encouraged to come up with new and better ways of doing things and when needed, are willing to put in the extra effort to get the job done. At the same time, employees feel that the agency is supportive of career-life balance. Questions related to performance management discussions between employees and their supervisors saw noticeable improvement between 2011 and 2012, reflecting NSF's efforts to improve performance management at the agency. Survey results continue to indicate challenges in managing workload and attaining sufficient resources to get the job done, which is consistent with the overall slightly negative trend in composite scores related to "my work experience."
The NSF 2013 Employee Viewpoint Survey Action Plan (Version 1.0) is intended to be a living document that will change and grow as NSF employees participate in its continued development. The current version outlines activities in four target areas; workload, career development, performance management and recognition, and career-life balance, and is based upon an initial analysis of the 2012 NSF Federal Employee Viewpoint Survey (FEVS) responses. Please stay tuned for upcoming collaborative activities that will offer opportunities for all employees to provide feedback and suggestions related to the improvement and implementation of this plan. Opportunities to participate will be announced via the Weekly Wire.
FEVS results are used by OPM to compare NSF against other agencies government-wide.

Since the explosion of the Deepwater Horizon rig in the Gulf of mexico on April 20th, the estimated fallout has increased rapidly. BP initially claimed the rate of spillage to be around 1,000 barrels of oil per day but we are slowly coming to the realization that this will be one of the largest spills of all time. Whilst BP continues to attempt to downplay the media reaction, the Flow Rate Technical Group has upped the estimate of the flow rate to between 35,000 and 60,000 barrels every day. To put this in perspective the spill has already far eclipsed the Exxon Valdez disaster, previously the largest spill in US history. Instead, this flow rate is approximately equivalent to an Exxon Valdez sized disaster every single week.
We've put together the above graph to help visualize the extent of the spill. Current estimates of Deepwater Horizon put it between 2.1 & 3.7 million barrels, which mean some believe it is already larger than the largest historic spill from a well: Ixtoc I which took place place in Mexico in 1979. The graphic also shows how small the Exxon Valdez disaster was in comparison.
The largest ocean spill of all time took place during the first gulf war, when Iraqi forces dumped the oil from a series of tankers in the Persian Gulf in an attempt to prevent the advance of US marines. However, this is no longer stands that much taller and its looking increasingly possible that this could be exceeded.
The only larger spill in history was on land, in California, when the Lakeview Oil Company caused a huge underground oil reserve to erupt whilst searching for Natural gas in 1909. The resulting spill is estimated at around 9 million barrels, which sadly isn't out of the question for the current spill. Hard to understand how BP exec Tony Hayward deems it acceptable to find time to sail whilst the fishermen of the Gulf remain rooted to shore.

Meyer: We can't throw Morne away
25 Sep 2012
Heyneke Meyer says dropping Morne Steyn from the Springboks' squad was not the solution to remedying his struggles.
Steyn has been the central villain in what has been a nightmare Rugby Championship campaign for the Springboks. His ball-in-hand play is widely perceived to be average, while his tactical and goal kicking has lacked its trademark accuracy.
There is a sense that a large portion of the South African rugby fraternity has lost patience with Steyn, the tipping point coming in their most recent Test against the All Blacks in Dunedin, where he missed kicks which were decisive in the final analysis.
Meyer has consistently voiced his view that Steyn's heavy workload over the last three years has compromised him and reiterated this after the Dunedin defeat once more. He intimated then that he would rest Steyn for the home leg, but said those plans were shelved in light of a ruling that requires Springboks players to compete in the Currie Cup if not in the squad.
'We need to look at how we manage our players but it was best that he stayed involved,' Meyer said. 'There is a lot of criticism [directed] at Morne, but you're still working with a human being. If you look at when Bryan [Habana] was struggling, as a coach you can't just throw a guy away and expect him to come back stronger. I'm not the type of coach to just throw a guy away.
'Obviously if you do stupid things there's no sympathy [Meyer would later suggest that Dean Greyling wouldn't play Test rugby again because of his cowardly assault Richie McCaw]. But Morne's general play was good, it was his kicking that was poor and we have to work on that. It is great to have him in the group, especially with Johan Goosen not being 100% fit [bruised heel]. I can already see being back home has helped him.'
Meyer continued to defend his gameplan, which is thought to be too conservative, stressing that his belief in its effectiveness hasn't diminished. 'There's been a lot of talk about the gameplan but I thought we played the All Blacks perfectly,' he said.
'We had more scoring chances than them but we finished poorly. We didn't convert pressure into points. The teams are so close in Test rugby that that is costly. It frustrated me today in training because when we broke the line guys didn't show an instinct to finish. They almost appeared to stop. We have to finish better. There isn't a lot to change in the gameplan, we just have to finish better.'
He also suggested that expectations need to be tempered in keeping with his infancy in the role. 'I've checked the stats, Steve Hansen has been with the All Blacks for 100 Tests. Robbie Deans has just surpassed Bob Dwyer's 65 Tests as coach. The Argentinian coach has been there for four or five years. I've been with the team for seven weeks,' he said.
'When you take over a new team with new coaching staff and players and take on the top sides in the world there will be a bit of self doubt for everybody. The players know they could have beaten Australia and New Zealand. But I sense the self-belief is growing. That comes with experience and we're short on that. But we're home now and the lessons from those defeats must show in our performances.'

25 Sep 2012, 13:38 pmI've checked again, Elton Jantjies has the perfect kind of hairstyle that I would like all Bok players to switch to
Even Heyneke
If that happens then Hannon can become the Boks' preferred hair products supplier
25 Sep 2012, 13:40 pmI'm sorry Meyer, you've lost any respect I had for you, Obviously provincialism in ingrained in your DNA and favouritism even more so.
Take a hike buddy, make way for Mallet or Carel Dup.
25 Sep 2012, 13:40 pm@i_love_u_bakkiesbotha-372: LOL nah he's definitely a keyboard warrior, that one
All p*ss and vinegar online, in real lfe wouldn't say boo to a mouse. I know the type well.
I wish he would sort out his mommy issues elsewhere, the guy needs serious professional help, he's crazier than a bag full of ferrets.
25 Sep 2012, 13:40 pmKeo, Why is 'none' not an option on the poll today?
25 Sep 2012, 13:42 pmnah, they are probably mates off the field.
25 Sep 2012, 13:43 pm@logie_Jumpbuck-402: I agree with Dusky, I also thought he would be better than this, thought he had more integrity.
I hear what he says about not discarding a guy like Steyn, but for goodness sakes, what's wrong with dropping him to a few Currie cup games to get his head right? Especially given how much pressure he will be under if he does start
25 Sep 2012, 13:45 pm@rangerman-399:
incidentally, the nifty 'give your buddy a pk to save us both getting a hiding' get out of jail card is one i'd like to pull on transie too, someday -
25 Sep 2012, 13:48 pm@Atreides-406:
he's a special one old pops.
and dont think reading about himself when we discuss him doesn't get his motor going….i bet he lives for this, like a junkie
25 Sep 2012, 13:53 pmI'm sure they are
25 Sep 2012, 13:55 pm@i_love_u_bakkiesbotha-408: Yea i sometimes wonder if he realizes what a despicable creature he actually is, but then I have to remind myself that trolls don;t think like normal people
Someone should let him in on the secret about the socioeconomic and demographic breakdown of rape occurences in SA too…he's barking up the wrong tree on an internet blog
25 Sep 2012, 13:57 pm@i_love_u_bakkiesbotha-350:
So a south african is now telling us all about the treaty of Waitangi.
You telling us the Maoris have been shafted yet not a whisper about your own country.
Bring up your stats. Bring up the stats for each tribe as they have been given different land settlements etc.
I for one dont think its in anyway a discussion point on a rugby blog.
When a South African talks cr@p about something that has nothing to do with them especially if they think the internet and the stats on there are gospel, i suggest shuting up. -
25 Sep 2012, 14:00 pm@rangerman-396:
So we will miss Carter, McCawsome and Nonu and you think FDP and Fourie evens it out.
lol, those players are not even in the same calibre as the ABs. -
25 Sep 2012, 14:02 pm@Sheriff-401:
i wanna cut that laaities hair so badly every time i see him play
he should go for a mohawk like mastriet's it would look a lot better than that terible wet whatever he's got going there.
does he cut his own hair? it really is an unusual style. -
25 Sep 2012, 14:03 pm@Atreides-410:
well, if pissinng in the wind's your thing then be my guest -
25 Sep 2012, 14:04 pm@Atreides-406: Exactly! He's acting like a father protecting his sons…..or worse, a Sheppard protecting his sheep. Who does he think he is?
25 Sep 2012, 14:04 pm@Hurricane-411:
stick around hurri old chum.
i'm putting you back in school here boet.
25 Sep 2012, 14:09 pm@i_love_u_bakkiesbotha-416:
I know exactly.I am a Maori. I know what my tribe has got and what is coming.
You go find your stats from the internet. I live here and am into Maoridom.
There is alot going down as we speak. But again you have no place in what NZ does when your own country is not any better.
I wont go down the road of throwing all your bad stats around as i dont really get a kick out of it.
But you seem to love it. -
25 Sep 2012, 14:10 pm@logie_Jumpbuck-415: I don't disagree with Meyer that players need to feel secure and know that a coach trusts them and won't boot them at the drop of a hat, but Meyer should have the guts to explain to him that he is being dropped for his own good, play a few cc games to get his form back and his head right, and that he needs to make his claim for the 10 jersey through his playing…not through some sort of right to the jersey as the incumbent
25 Sep 2012, 14:20 pm@Atreides-418: It's sport ffs! If you're not good enough you get dropped. That's how it works.
25 Sep 2012, 14:21 pmPops had another meltdown?
25 Sep 2012, 14:23 pmBe careful now.
We have moved from 'eendrag maak mag' to 'unity in diversity'
It's a way for him to express himself, in other words: this is me, world. I like that about him. Some guys wear expensive watches and then make sure that they put it on display there for you and me to see (not just juju)
Do you think Heyneke discriminate him because of hi unique hairstyle?
I dont see him doing that with Francois Yoghurt. The only stat of him that has improved is the number of tattoos but that's ok with Heyneke…
25 Sep 2012, 14:26 pmBy the way, I see Meyer suggested that DeHan Greyling will not play for the Boks again.
1stly – why call him DeHAN when his name is clearly 'DEEHN'; why create that type of confusion in world rugby?
2ndly – why choose him in the first place? You need not be a rocket scientist to see that this is the type of 'betrek klap' Loftus bloke
Why, I ask you: why??
25 Sep 2012, 14:28 pm@Dawn-420: Where does one end and the next one start?
25 Sep 2012, 14:39 pm@Sheriff-422: want hy is n buffel….n bakkies botha tipe. we needed one, only not so dom.
25 Sep 2012, 14:53 pm@Hurricane-417:
no, no kicks hurri.
we dont have to talk about it.@Sheriff-421:
look, there are a number of ridiculous hairstyles out there, even hair colouring going on. i just think it could be made to look a lot more appealing if it was professionally done. for me it does not suit him at present.the same or at least similiar look suits mastriet and blommetjies the way they have done it.
and no, its not about his hairstyle its about his style of play and some or other seemingly negative (or at least lesser) perceptions meyer has about him.
its the same for lambie, who meyer does not rate as a flyhalf
or hougaard, who meyer does not think is up to bok scrumhalf ability at present.
or daniel
or potgieter
or brussow -
25 Sep 2012, 15:03 pmSo Meyer soek buffels in sy span?
Met ander woorde: hy is 'n buffel coach
G'n wonder dit gaan so sleg met ons nasionale rugbyspan nie
Wa' het jy nou al gehoor van 'n buffel coach?
25 Sep 2012, 15:32 pmIm probably repeating what has already been said here, but I dont think anyone is talking about "throwing away".
We ARE talking about giving a tired, struggling player a break.
HM's reasoning that Morne would play for the Bulls anyway is flawed cos Currie Cup is not Test and Morne would be able to get his groove back.We ARE also talking about picking players on form and trying to win every Test (both aims that HM himself announced).
If someone like Spies suddenly hits amazing form (I hope it will happen!) then play him at 8 again.
If Morne gets back his metronome for kicking, then bring him back.Right now, there are better options for the team. That is sport, that is trying to win, and that should be the Springboks.
25 Sep 2012, 15:35 pm"when we broke the line guys didn't show an instinct to finish. They almost appeared to stop." – this is because they are not used to breaking the line! Esp with a kicking fly-half (and usually a kicking scrumhalf!).
Bryan Habana WAS struggling and shouldve been dropped to play Currie Cup. He is still not 100%, but he is better.
If Goosen is injured, then Elton can start (he should be starting IMO). Morne on bench even if must be
25 Sep 2012, 21:48 pmTo be fair to Morne, we should kick him away.
25 Sep 2012, 21:53 pm@garth-429: If HM soo truely worried abt MS workload and fact that if dropped out he'd still end up starting in Currie Cup…he really could just not have him in match 22 and he'd get the rest he needs!
Win win -
25 Sep 2012, 22:21 pmAs an all black fan, I find all the hand wringing about protecting this that or the other no10 extremely perplexing.
NZ rugby lore is that the no10 is the most important player on the field.
Morne steyn singlehandedly lost the bold the game in Dunedin. If he had kicked his kicks you would have won. It would be irrelevant to an AB coach that others also blew try scoring opportunities – morne himself could and should have won the game for you, or on a bad day would have kept you within a single penalty of the win and earned you field position in the AB 22. To fall so short of those requirements would mean only one thing for an AB No10 – immediately dropped.
It would not matter who was coming up behind, or how inexperienced they were, they would be dropped and someone else tried.
Poor form is less clear cut, but without a doubt morne's extended run of poor form would have seen him dropped from the ab's before Dunedin.
All of this would happen without consideration of who the alternatives were – the assumption being that trying someone new has to be better than the status quo.
It astounds me that book rugby lacks this ruthless commitment to performance. But what astounds me even more is that you worry about dropping steyn for fear of the pressure this will put on either goosen or janties. This is ridiculous – you have frans steyn to kick the goals if need be, and two good no 10′s in the team already in the form of pienar and lambie their presence can be used to take pressure off the new guy (eg taking kick offs, doing more of the kicking in general play etc).
The all blacks used this system so effectively with weepu and cruden at the wc, until weepu injured his groin in the warm up for the final.
To put it in perspective, the bols have far better cover for no 10 in the match day 22 at Dunedin than the all blacks had available in Te whole of the World Cup. This is even excluding janties who wasn't at Dunedin.
Honestly, it is beyond bizarre that you don't drop steyn and start working with he incredible depth you have in the rest if the team.
Change isn't a guarantee of immediate success, and this strategy has resulted in some terrible 10′s playing for the Ab's (bachop, Donald),BUT overall this strategy has served the all blacks incredibly well over the last 20 years.
25 Sep 2012, 22:35 pm@corporal punishment-431: This must be thee most astute comment I've seen on this blog in sometime and needs to be framed
We need to summon Transie to archive this along with his other transcripts!
Its beyond me that we feel we can't drop MS and not back of the other youngsters, his performance singe handedly cost us the game, not Greyling and performance wise he should be dropped…End of story!

text: I Too Am Health Conscious About half a year ago was when a friend of mine introduced me to running. Since those were the days that I'm also half a year removed from being solely employed for a company, I really didn't have many friends. Its one downfall of people who rely on online freelancing to earn a living, you'll have to actively seek out people to be social with. Otherwise, you can really turn into a hermit inside your home or apartment. So there I was, out of shape and letting all my social skills drift. Perhaps it was my friend's intention to get me into a much active lifestyle or maybe it's just coincidence, I don't know because I haven't asked him yet. Whatever the case is, running has made me appreciate health. It's as simple as that. Sure there will be folks who's going to throw some arguments at you abour running and endurance sports in general, but really, you have to listen more to those who's enjoying it. Their opinions about running should be magnified enough for one to wash out the voices of two pessimists. Let me recount how my life is now three times as fun because with my friends' help, my outlook on being healthy has totally turned around. One argument that you would often hear, and I've shared this one too previously, is that being healthy takes too much time out of your day before it becomes effective. This is true, but if you dig a little deeper, there's more out of this statement that would actually benefit endurance sports more. Although activities like running does take a huge chunk of one's time, the benefits you'll gain by being physically fit far outweighs the limits naysayers are spewing. A healthy person does his work more efficiently because he's more likely to have better focus, more active brain cells, improved posture, positive thinking, all because he engages in endurance sports. Remember what having a healthy lifestyle can give you and how it positively affects your overall performance, which includes work. Thus, you don't even have to spend as much time with your duties. Because you simply breeze through them faster if you're at tiptop shape. Another wrangling thrown out by people who probably haven't even experience being health conscious yet is that endurance sports, like running, can be dangerous. While some parts again of that statement is true, do not easily be discouraged. Like most lessons in life, we have to be critical and not readily accept things as factual. Do not forget that being a sack of potato lying around during your weekends has its downsides as well. Something as simple as coffee has its dark and helpful sides. Too much caffeine is bad for you, but with proper intake, some form of coffee has garcinia cambogia, which does help a person to become fit too. I hope that your takeaway from this article is for you to have the tendency to balance things. Do not get easily discouraged by people who tell you not to do activities just because they haven't tried it themselves. |

Remembering American Bandstand's 50th [Photos]
HI remember watching Dick Clark and the American Band Stand on Saturdays around noon or 1pm and I enjoyed watching everyone dance and all my favorite singers come out and sing! Dick clark did alot of wonderful things and I know we will never forget him! His body is gone but his spirit will always be with us. As far as I'm concerned he'll always be alive with us. I will pray for his family that God will give them strength.

Web edition: August 14, 2012
A mechanical glitch on NASA's Dawn spacecraft will delay the next leg of its voyage through the asteroid belt. But the defect shouldn't keep the probe from completing its mission with a visit to the dwarf planet Ceres.
On August 13, the Jet Propulsion Laboratory announced that Dawn had lost the second of its four initial reaction wheels. Electrically controlled by onboard systems, these wheels precisely aim the spacecraft so it can acquire images and data. Dawn is tasked with taking detailed measurements of two targets: the enormous asteroid Vesta, where it's been for the last year, and the dwarf planet Ceres, its next destination.
Though team members aren't yet sure if the wheel is gone for good, "if we cannot recover it, we already have the capability onboard to operate with two wheels," says chief engineer Marc Rayman of NASA's Jet Propulsion Laboratory in Pasadena, Calif. "I think the prognosis is terrific."
When one of Dawn's four wheels went down in June 2010, the team quickly put together a plan for operating on two wheels. On August 9, news of a second wheel's demise reached mission control during a routine communications relay with the spacecraft. The cause, "excessive friction," is the same culprit that struck before.
Dawn launched in 2007 and arrived at Vesta in July 2011. The craft has studied the asteroid's surface, composition, and internal structure, revealing such features as grooves spanning the equator, a crater housing one of the solar system's tallest mountains, and an iron core.
The misbehaving wheel has delayed Dawn's Vestal farewell by about nine days. The craft will escape Vesta's gravitational bind and begin its 2.5-year journey to Ceres on September 4. "We were going to fly from Vesta to Ceres with the wheels off anyway," Rayman says.
News of the reaction wheel's demise comes on the heels of a similar announcement about NASA's Kepler spacecraft, which stares at more than 100,000 stars looking for orbiting exoplanets that periodically dim the stars' light. On July 14, mission managers announced that Kepler had also lost one of its four reaction wheels. The craft can operate on three wheels, but not two, since detecting planets requires very precise aiming. So unlike Dawn, Kepler is in trouble if another wheel goes.Suggested Reading

If you are looking for a place to wash up and rest overnight or chat with friends, why don't you head to one of the numerous "jjim jil bang" with many sauna rooms, each of which has particular characteristics: charcoal, oxygen-saturated, salts or mineral infusions.
A jjimjilbang can be found in almost any Korean neighborhood, sometimes as part of a hotel and often stand-alone. It is actually more than a regular public bathhouse or sauna. It is like a meeting place. Entire families can be seen wiling a night away at a jjimjilbang. There's usually a large central space with a big-screen TV, where patrons communally watch the latest drama or sports match, sprawled out over the ondol floor. A room off to the side offers massages. As well as juices, energy drinks and other beverages for sale, there's often a simple restaurant where basic Korean dishes can be enjoyed.
[Source : Korea.net]
All jjimjilbang are open 24 hours a day and cost anywhere up to 10,000 won to
enter (there's frequently an extra night charge after 8pm or so).

Due to popular demand, today's recipe is how we make granola bars in our house.
These are amazingly delicious, and my fiance even likes them, and he doesn't like granola bars.
Not only are they yummy, they're packed with all sorts of ingredients that are good FOR you! Nutritional yeast is one of those good FOR you ingredients.
What's nutritional yeast you ask?
Well, it's a yeast grown on beet sugar and molasses, then fermented and dried so it's gluten free and won't form yeast in your body. It's great for nursing moms (helps with milk production if you're "feeling low"!) and is beneficial for babies who aren't nursing.
It is SUPER rich in B vitamins (just 1Tbsp contains 100% of the daily B12 recommended for an adult), a great source of 18 amino acids and 15 minerals (including phosphorus, zinc, selenium, iron and magnesium). It also contains protein, folic acid, biotin and a load of other vitamins!
It's sometimes available in your bulk section, or you can order it on Amazon!
So without further ado, I give you…..
- 2 cups old fashioned oats (I use the Quaker Oats, but Bob's Red Mill makes some good ones too)
- 1 cup chopped nuts (measure them AFTER you chop them..I used almonds)
- 2T sunflower seeds (totally optional)
- 1/4c nutritional yeast
- 1tsp pure vanilla extract
- 1/3c honey
- 1/3 agave syrup
- 3T coconut oil (or homemade coconut butter, if you're so inclined..recipe here: http://www.crunchybetty.com/coconut-butter-recipe-3-steps-to-bliss)
- 2 cups chopped dried fruit (for this batch, I used apricots and dried cranberries...look for fruits that are unsulphered and where fruit is the only ingredient)
- palmful candied ginger, chopped
- Trader Joe's Dark Chocolate Cocoa Nibs (usually by the register, in a little mint-type tin. Can't find another place to get these, but they're totally optional)
- Preheat the oven to 350F. Butter (or use coconut oil) a brownie pan (8x8) and line with parchment paper. (DON'T use wax paper. Your granola bars will taste like candles. Ew.)
- On a rimmed baking sheet, add oatmeal, nuts and sunflower seeds (if using). Stir to distribute evenly. Bake for 8-10 minutes, stirring occasionally, until fragrant and lightly browned. WHILE you are toasting these, melt the coconut oil.
- Remove the oatmeal mix from the oven into a large mixing bowl and reduce oven temperature to 300F.
- Stir in nutritional yeast. While mix is still warm, add all other ingredients EXCEPT cocoa nibs. Stir until well-combined.
- Pour mixture into prepared pan and using a spatula (or your hand in a plastic bag), press until mix is even and tightly packed.
- Bake for 20-25 minutes, until edges are browned. (Bake for 20 if you want chewy, not crunchy bars).
- Right after removing from oven, scatter cocoa nibs (I used half the tin, but you can use more if you'd like) and press them into the surface of the granola.
- Let cool for 2-3 hours and then cut into squares or bar shapes. You can store these in the freezer if you'd like, they stay good in an airtight container at room temperature for about 2 weeks.
Now it's you turn! Please link up your healthy recipes below:
