It's actually much less effort just to edit an .fgd file to alter it
for the coodinates of each map. This is the voice of experience speaking 
here :)

The coordinates are listed in the four corners of each map image.

What I am wondering is why the .fdg is needed at all, since the tif file
contains the map coodinates - can't the masking be done based upon the
tif info? Is some key portion missing??
