[mapserver-users] WFS Intersect with gml:box

[Rahkonen Jukka]

Hi,

Have you copied the uDig request right?  I suppose the filter is <ogc:Intersect/>. At leas my Geoserver sends that in the GetCapabilities.

For information, wile using "box" is OK with WFS 1.0.0, some old deegree based WFS clients (OpenJUMP WFS plugin at least) are offering the "box" also with WFS 1.1.0 requests, but GML3 does not support box and those requests are invalid. Should use anvelope of something else instead.

 I have seen some examples of intersects used with gml:polygon, but it should work too with box, right??

Thanks for reading!
