Well, I think the easiest thing to do would be to make a
GeoTIFF image that you could easily read into ENVI. You will
have to project your data to create the projected image.
If you are familiar with the MAP_PROJ_*** routines, I would
use those. Otherwise, you might get away with MAP_PATCH.

You can probably get a start on how to fill out the
GeoTiff structure (for this you *will* have to learn
how to use the MAP_PROJ_*** routines) by having a look
at this article, which uses an Albers map projection:

http://www.dfanning.com/map_tips/tiffoverlay.html

This process is not for the faint of heart, unless
someone knows an easier method in ENVI. (I which case,
I am all ears, too.)

Cheers,

David
