I mention resolution because sometimes journalists ask for “the original picture in full resolution” and are somewhat disappointed at what I could send them.

This close-up of Boston demonstrates very clearly the difference between 10-meter and 0.8-meter resolution. In the SkySat image you can also see the “leaning” effect of the skyscrapers, not imaged at nadir (from directly overhead) but at a slight angle.

Sentinel-2

The 10-meter resolution of the Sentinel-2A satellite seems not very attractive in this close-up, however, don’t let that fool you. When showing bigger areas, the 10-meter resolution delivers superb images, as can be seen here in this image of the Sermilik Fjord and surrounding glaciers in Greenland.

Landsat

The Landsat satellites have a similar resolution with 15 meters per pixel and deliver comparable results. Because the Landsat program is much older, the archives of images are especially interesting and important for time-series stretching over a longer period of time to show changes and monitor slow processes.

Now that is looking odd…

Some common surprises when looking at natural color satellite images include colors that look a bit wrong and less saturated than expected and often some kind of haze in the image.

Forests for example can look surprisingly dark and not at all as green as you might expect them to be. Images also often show a somewhat bluish tint, this is caused by atmospheric scattering of the light which is stronger at shorter (blue) wavelengths.

This bluish tint and haze can sometimes be experienced when looking out of the window of a plane, but because of the higher altitude of remote sensing satellites and therefore more atmosphere to penetrate, those effects are usually more pronounced here. More information on this effects you can also find here.

Atmospheric correction

Atmospheric correction can be used to reduce the impact of the atmosphere on the image quality. Some data providers deliver images that already are corrected, but sometimes you have to do it on your own.

There are several methods to do so, some very scientific, others more artistic in their approach. Which one you need depends on your application, for usage in
