Hi Chris,
I am also interested in such a routine.

Chris,
Is there any chance you could post this routine for us to download?
Thanks,

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.
