|Google Earth |Plate Carré\\ (Simple Cylindrical projection) |WGS84 |http://earth.google.com|
|Yahoo Maps |Mercator |WGS84 |http://maps.yahoo.com|

FIXME - 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)
