What I am curious to try is to convert pixels that have already
been placed in a projection to another projection by means of
sending them through the UV coordinate system. This is probably
what your ImageMap already does, but I'm teaching this material
next week and I don't understand it fully until I actually do it myself.

I can imagine there are some projection combinations where
this is nearly impossible to do. But I can imagine others that
are easy. I just wanted to play with this a bit to see what
the issues are.

So, I guess I am looking for images already resampled to a map
grid. I'll leave the sensor projections for the advanced class. :-)

Cheers,

David
