I've been working with the USGS Counties and States maps (located at
nationalatlas.gov) and the GIS maps from the NOAA and I've been running into
a stumbling block. I've been able to get the maps to display but it seems
that the mapserv cgi app only pays attention to one of the extents.
I'll copy my map file below but for my example use the following line:
EXTENT -100.05 37.1 -94.85 37.85
It seems to fit the -100.05 and -94.85 just fine on the map and that gives
me the coordinates I need on the X axis but it never seems to follow on the
Y-axis. Its like it tries to create something porportional. What the end
result is a map that is squished from top to bottom. (see at
http://www.aspiredillusion.com/cgi-bin/mapserv?map=/nexrad/map/nexrad.map&mode=map
)
Has anyone else experienced this or know of a way around it? Here is the -v
info from mapserv:
