AW: [OpenLayers-Users] Re: How to test if a point is within WMS layer?

Instead of wfs you can use a WMS GetFeatureInfo Request.

I use this approach to determine which country the user clicked.

Betreff: [OpenLayers-Users] Re: How to test if a point is within WMS layer?

So I created a test polygon in GeoServer called test:allPoly and a test
geometry point in OL called 'point'. Currently the point is outside the
polygon but the wfstest layer still shows up. Shouldn't the wfs polygon be
'filtered out' with the code below?

var wfstest = new OpenLayers.Layer.Vector("Flood Vector Test", {
	strategies: [new OpenLayers.Strategy.BBOX()], visibility: false,
	protocol: new OpenLayers.Protocol.WFS({
		url:  url,	
		featurePrefix: "test",
		featureType: "allPoly",

		version: "1.1.0",
		srsName: "EPSG:900913"
		}),
            filters: [new OpenLayers.Filter.Spatial({
		type: OpenLayers.Filter.Spatial.INTERSECTS,
		value: point}) 
		]
});
