[Mapserver-users] units question

[Dave Walton]

I have a shapefile which ogrinfo describes as below.  It displays quite
nicely in MapServer.  However, I have to use meters for EXTENT, and when I
produce a GeoTIFF image, the coordinates are in meters.  I would very much
like to be able to specify EXTENT in decimal degrees, and have the
coordinates in the GeoTIFF in decimal degrees.  How can I set up MapServer
to do this?
