Projections Used By Popular Programs
| Program | Projection | Datum | URL |
|---|---|---|---|
| Google Maps | Mercator | WGS84 | http://maps.google.com |
| Google Earth | Plate Carré (Simple Cylindrical projection) | WGS84 | http://earth.google.com |
| Yahoo Maps | Mercator | WGS84 | http://maps.yahoo.com |
- the sites I have read about Google Earth all say it uses Plate Carré, but this needs verified because it seems as if it warps the image since a round globe is presented (not sure what happens when we zoom in to approx 2000 ft height)
