Hi, How about doing two WFS requests in a row? In pseudo SQL
1) select geometry from town_polygons where town='my_town' 2) capture the geometry from the previous and use in the WFS Intersects filter select * from my_features where [attribute filter] AND [Intersects filter with selected_town_polygon] I know it is doable, we use that in some OpenLayers applications just like you plan. User can draw a polygon or select a region name from a drop down menu which makes the application to do the first WFS query automatically. -Jukka Rahkonen- ________________________________ Bistrais, Bob wrote: > Interesting thought.

If so then just set that as your map extent as part of doing your attribute query (attributes always do both). There are other options too, let us know more what your spatial query is.

I need to query several layers, selecting based on an area, then select from that selection based on an attribute value. It would be OK to query by the attribute first, then spatial. _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
