Does anyone know the IDL map projection to use to make a
ground overlay in a kml file (to be viewed by a geobrowser such
as google earth?)

I've googled and have seen many different things stated,
so I am not sure if my use of cylindrical projection is right.

My figures are off, in that my continents do not match earth's continents
I am initiallty making a full globe image (-90 to 90 lat , -180 to 180 lon)
similar to the big blue marble example.

but my image of the global map, does not reproduce the continents like
in those images.

cheers,
