Hi David,

I have a routine to convert from a GeoTIFF structure into map projection
properties, to be used in the iMap tool. Perhaps you can take some ideas
from that code to do the opposite. I will send you the code offline.

Converting from IDL's map projections into GeoTIFF is actually easier,
because there are only a limited number of map options. (Converting from
GeoTIFF back into IDL is much harder because GeoTIFF supports so many
different projections, datums, etc.)

Good luck.
