I got this file from the Arizona DOT. It appears to be a GeoTIFF in Arizona
Central NAD83. However this is the output from gdalinfo (I tried several
versions of GDAL):
 
Note that at the end, I am getting very odd lat-lon for the corners. This
mirrors what I am getting in my .NET program.
 
Any ideas?
 
Download the file from:

Thanks for any assistance!
