Thanks for the hint, Markus.

I never did check the actual SRID since I was trying to mix a database
layer with some shapefiles in the mapserver. However, the SRID comment
got me thinking about projections and that's what my problem was. My
database layer and the shapefiles were not in the same projection. It's
working better now.

Thank you,
Frances Collier

Hi, Frances,

No, this is the correct directory for PostgreSQL extensions like
PostGIS.

This output tells us that your PostgreSQL has successfully found the
liblwgeom.dll, and works with it.

Thus, the problem has to be somewhere else, maybe your MapServer query
definition.

Does Mapserver return any error messages? What SRID is your data in, and
what does Mapserver expect?

Maybe the Mapserver experts here or on the Mapserver list can give you
more help.
