Added a projection layer for the postgres data and it works like a charm. Sorry to \
have taken up bandwidth ...

Subject: [postgis-users] on-the-fly MMS reprojection with PostGIS?


greetings - I am trying to use Minn Map Server to specify an output file in one \
projection, and add PostGIS layers that may exist in another (mostly EPSG id 4326). \
I'd like to simply tweek the EXTENT and the PROJECTION tags of the overall map to \
change the outputs. 

A simple mapfile (derived from the itasca demo) I am trying is below; but \
unfortunately this doesn't seem to work properly...

What's the proper way to change output projection, if the PostGIS tables are in \
various projections, and properly loaded into the geometry_columns table?

thanks in advance!
