Hi All:
I'v gotten the demo to work on my Red Hat 5.2 system. (thanks Steve).
I am
trying to get up to speed on GIS since I'm a newbe on that. I have a
question on EXTENTS.
I assumed that the coordinates were a datum like WGS84. I have looked at
the EXTENT in
demo.map and at my trusty aviation sectional and I don't understand how
to relate the two.
What am I missing? How do I relate lat. lon. to EXTENT. Also in my shape
files do I put in lat. lon.
or EXTENT coordinates.
I know these are basic questions but I have searched around and have
come up empty
on answers.
TIA
Mark C.
