The problem that I am running into is that only the middle half or

Do I have to set some region or something to get it all to work?
Yep, exactly.
AFAICT, the georectify tool calls i.rectify with the -c flag (line
1366 of gui/tcltk/gis.m/georect.tcl), which means "Use curr. region
settings in target location". So you need to set the correct
location in the target location.
I'm not sure I understand why this is so. It would seem to be more
intuitive to run without that flag and thus have i.rectify
"determine the smallest window which covers the image", because
otherwise the user has to identify target region extents manually...
Michael, any special reason for using -c ?
I can't remember, but think it was to avoid a situation where someone
is rectifying part of an image and must wait (sometimes for a long
time) while the entire, very large image is rectified.
Maybe this could be made into an option ?
This is a good idea.
Michael
