title: Openlayers 3 coordinate conversions
body: <p>Newb alert: I'm completely new to OpenLayers 3 and mapping in general. My background is in SQL Server, and back end systems design. I have no experience in HTML, JavaScript, web development etc. I'm sure this is a very simple issue but I can't seem to figure out the details.</p>
  
  <p>I've modified one of the samples for OpenLayers.org and it doesn't behave as expected. It uses a GeoJSON object and draws points on the map, but they don't end up where expected. Apparently there is some conversion or something that happens.</p>
  
  <p>The sample I used is here: <a href="http://openlayers.org/en/v3.7.0/examples/geojson.html" rel="nofollow">GeoJSON example</a></p>
  
  <p>My test map is here: <a href="http://74.69.121.94/" rel="nofollow">Test Map</a></p>
  
  <p>The GeoJSON object is defined as</p>
  
  <pre><code>        var geojsonObject = {
              'type': 'FeatureCollection',
              'crs': {
                  'type': 'name',
                  'properties': {
                      'name': 'EPSG:3857'
                  }
              },
              'features': [
                {
                    'type': 'Feature',
                    'geometry': {
                        'type': 'Point',
                        'coordinates': [0, 0]
                    }
                },
                {
                    'type': 'Feature',
                    'geometry': {
                        'type': 'Point',
                        'coordinates': [-8.575653e6, 4.70681e6] 
  //White House, Washington DC Lon -77.03648269999997 Lat 38.89767579999999
                    }
                }
              ]
          };
  </code></pre>
  
  <p>Through a little trial and error, I was able to get my point to display on the White House Lawn (NSA has no doubt flagged this conversation) and there is no resemblance to the latitude and longitude I pulled from a different source. I understand that the order of coordinates is [lon, lat] but I can see no rhyme or reason that -77.036 = -8.575e6. The other point [0,0] displays right where I would expect it.</p>
  
  <p>I have tried to figure this out myself and searched quite a few places, but I can't seem to find the answer.</p>
  
  <p>Also, if you could direct me to any good tutorials, it would be most appreciated. Thanks!</p>
