[OpenLayers-Users] WFS GetFeature with Mapserver

[Berényi Attila]

  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.

Cheers,

Attila
