745473.8751627404, 72029.90624999696, 1242053.0000937672, =
1023283.999999998


(The coordinate system info above is from the prj file.)


So for a spot near the southern border, I am expecting a northing close =
to 72030 (72,030), but I am getting 21966.03 (21,966).


My easting numbers are closer but not right on.


(I am using proj rel. 4.7.1, 23 September 2009, which came with ubuntu =
12.04.)


If someone can see what I am doing wrong, I would appreciate some =
guidance.


Thanks,


Rick Graves
