It hadn't actually occurred to me to try this before. I do have one
question, and one unrelated question:

1) Is there a way I'm overlooking to decollar collared maps (in GeoTIFF
form) or is it expected that an external program would be used for this? I
understand that the georeferencing is insufficient to know where the image
corners are, but I have other data which can be used for this.

2) Is there a simple viewer wrapped around GDAL I can point someone at
who wants to support GDAL in an existing viewer program? (Is what's in the
"viewer" subdirectory the best option for this?)
