[mapserver-users] Mapfile from Postgis, just Background No Map?

[Fawcett, David (MPCA)]

I see a few potential issues with your mapfile:


1.        For testing, set your layer STATUS to DEFAULT or add '&layer=tb_kasusdbd' to your URL

2.       You have two entries for UNITS (DD and KILOMETERS).  You should only have one of these lines, and the units should match the units of your output projection.  So, if your data really is in geographic coordinates (lat/long), your units should be 'DD'.

3.       The values in your EXTENT line look weird.  The values in your EXTENT need to be expressed in the units used by your output projection/spatial reference system.  If your data is in geographic coordinates, these values are invalid.  If your data is in some other spatial reference system, you will need to change your UNITS to match that SRS.

David.
