Why not use a GetFeatureInfo request using your x,y inside a small bbox and see if you get attributes returned relating to one of the polygon geometries in the WMS layer? Take your x,y point, create a small bbox round it and then use the width and height parameters to represent your point in the middle of the bbox eg.

If that's not what you need, then you probably need topology rule enforcement. I assume you want to persist the user generated geometries on your GeoServer as well? That can be done as part of WFS transactions, using pre- and post-transaction hooks on the server. The first step would be to see why your GeoServer does not respond to WFS request, but that's a question for the geoserver-users list." I don't have any user generated geometries for this scenario. I simply want to test whether a point is within a polygon geometry sitting on GeoServer. I figured out the GeoServer is actually responding to the WFS request for the polygon but there are LOTS of vertices so it not feasible to use the WFS approach to determine whether the point is within the polygon. -- View this message in context: http://osgeo-org.1560.n6.nabble.com/How-to-test-if-a-point-is-within-WMS-layer-tp4341265p4341729.html Sent from the OpenLayers Users mailing list archive at Nabble.com. _______________________________________________ Users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/openlayers-users This email and any attachments are confidential and intended solely for the addressee(s).
