[mapserver-users] WFS Spatial Filter Problem

[Fawcett, David (MPCA)]

Bryan,

For testing, I would enable debugging at the MAP or LAYER level.  If you set DEBUG 5, I think that you should be able to see the query that MapServer is crafting.

More on debugging here:  http://mapserver.org/optimization/debugging.html#debugging

Dear Kai and Assefa,



After you two guys requested me to send you my setup, I exported the content in the databasetable to a shapefile so you can test it. When I tested the spatial filter right after that, it suddenly worked ! This narrows down the possibilities:

- The request I send is definitely not the problem anymore. It works with MapServer + shapefile and with GeoServer.

- I exported only the geometries to the shapefile in the table with geometrytype = POLYGON because from ~8000 geometries ~10 are linestrings. So I investigated possible problems with the linestring geometries by telling the MapServer not to serve them using a subquery in the mapfile:

DATA "the_geom from (select * from alldata where geometrytype(the_geom) = 'POLYGON') as subquery using unique product_id using SRID=4326"

Error 500 still occured. Therefore, the data can't be the problem neither, right?

- Since I didn't change anything else MapServer must have problems communicating with the PostGIS database, but why Error 500 then?

Here is my mapfile:

    END

END


Does anyone see a problem with the setup?

Many thanks to Kai and Assefa for the help so far! I am going to send you the shapefile (which you could import into the database with pgsql2shp), the mapfile, and my client.

Kind regards,
Bryan
