I'm a newbie to mapping in general, so please have mercy if I'm asking stupid questions.
I have a shapefile that was given to me in Nevada State Plane, and I used shpproj to reproject as follows:
shpproj stateplane_shapefile geographic_shapefile -i="init=nad83:2703 units=us-ft" -o=geographic
The map looks perfect when I view it in xastir (ham radio APRS mapping program) but looks about 30% too wide when viewed with mapserver.
Here's the map file... Any ideas what I'm doing wrong?
thanks for reading this far.
