&buffer=myDistanceInPixel and you will control manually how big the hitbox is. http://docs.geoserver.org/latest/en/user/services/wms/vendor.html#buffer >> If you are worried that GetFeatureInfo is returning too much >> information you'll be happy to know that I'm about to implement >> property selection for GetFeatureInfo, pretty much the same way as >> GetFeature works > That would indeed be good - as would GML option for returned. GML 2 is alredy there, has been for years, example: http://demo1.geo-solutions.it/geoserver/geonetwork/wms?REQUEST=GetFeatureInfo&EXCEPTIONS=application%2Fvnd.ogc.se_xml&BBOX=-32.715%2C-3.355508%2C28.817%2C36.784508&SERVICE=WMS&VERSION=1.1.1&X=348&Y=143&INFO_FORMAT=application/vnd.ogc.gml&QUERY_LAYERS=geonetwork%3AWDPA&FEATURE_COUNT=50&Layers=geonetwork%3AWDPA&WIDTH=512&HEIGHT=334&format=image%2Fpng&styles=&srs=EPSG%3A4326 The mime type is not particularly useful or nice, but that's what the WMS 1.0/1.1 spec suggests if you want to return GML2 Cheers Andrea -- ------------------------------------------------------- Ing.
