[Xastir-Dev] problem with drg geotiff maps

[J. Lance Cotton]

I was playing with the .fgd files from these DRG-E's. I know that they 
are 7.5 minute 'windows', and the bounds in the FGD don't match with 
that. I assume that's because they have been re-projected in some sort 
of rectangular something-or-other. I'm not a GIS person, I just like to 
look at maps :-)

What I got was a partial display of the DRG-E, but it did not quite 
match up, as to be expected.

In the mean-time, I went ahead and just paid $10 and downloaded some 
DRGs from www.mapmart.com ($1 per 1:24k DRG, minimum $10) and they work 
fine. It wasn't *that* much and I got some maps of my parent's homestead 
as well.
