The output from listgeo is this...
Corner Coordinates:
Upper Left ( 360427.280,3278421.510)
Lower Left ( 360427.280,3270801.510)
Upper Right ( 367182.280,3278421.510)
Lower Right ( 367182.280,3270801.510)
Center ( 363804.780,3274611.510)
The corner coordinates in Decimal Degrees should be
Upper Left ( 29.628626,-94.441707)
Lower Left ( 29.559135,-94.441707)
Upper Right ( 29.628626,-94.371019)
Lower Right ( 29.559135,-94.371019
What I get is...
-1.648319,0.517104
-1.648302,0.515904
-1.647101,0.517117
-1.647085,0.515917
This prompted me to look at the PJ structure in debug mode (watch)
In my Visual Studio 7 IDE. I saw the following string in the
description...
+ descr 0x0043802c "Universal Transverse Mercator (UTM) Cyl, Sph
zone= south" const char *
Funny how I didn't specify "south".
This led me to believe I need to specify more parameters.
