Dear All, Finally I had some time to summarize my experiences with Mapserver's and OpeLayers' WFS GetFeature functionality. I've created a few pages showing different usage of the above mentioned services.
WFS GetFeature Example, using MapServer and OpenLayers.Protocol.WFS.fromWMSLayer: - one typename: http://webgis.fmt.bme.hu/howtos/getFeature1.html - two typenames: http://webgis.fmt.bme.hu/howtos/getFeature2.html WFS GetFeature Example, using MapServer and OpenLayers.Protocol.WFS: - one typename: http://webgis.fmt.bme.hu/howtos/getFeature3.html - two typenames: http://webgis.fmt.bme.hu/howtos/getFeature4.html I hope these pages will be useful for everyone playing with Mapserver and GetFeature service.
