Mercator maps?

[Joey Mukherjee]

I have a need of making flat mercator maps of the earth and displaying a surface 
above it.  I know VTK has an EarthSource and I can display the surface above it 
(thanks Ken!), but its a round globe.  I'd like to do the same thing on a flat 
map of the earth.

Any ideas how I could convert the data in the EarthSource to a flat plane 
instead of a sphere?

Thanks!

Joey
