[mapserver-users] WFS Intersect with gml:box

Tue Mar 29 14:07:01 EDT 2011

Hi Jukka,

My mapserver's GetCapabilities also sends ogc:Intersect, but somehow it is also accepting Intersects ( I dont know which one is the standar, but it seems like geotools uses intersects)

http://localhost:8080/cgi-bin/mywfs?WIDTH=512&SERVICE=WFS&VERSION=1.0.0&REQUEST=GetCapabilities
....
  <ogc:Spatial_Capabilities>
    <ogc:Spatial_Operators>
      <ogc:Equals/>
      <ogc:Disjoint/>
      <ogc:Touches/>
      <ogc:Within/>
      <ogc:Overlaps/>
      <ogc:Crosses/>
      <ogc:Intersect/>
      <ogc:Contains/>
      <ogc:DWithin/>
      <ogc:BBOX/>
    </ogc:Spatial_Operators>
  </ogc:Spatial_Capabilities>
...

I copied the filter directly from debugging:

29-mar-2011 19:59:21 org.geotools.xml.XMLSAXHandler processException
GRAVE: msWFSGetFeature(): WFS server error. Invalid or Unsupported FILTER in GetFeature : <Filter>

I installed mapserver with fgs-mapserver_basic_5.6.3-fgs_9.5-linux-i386.bin

It is weird that the BBOX filter works, and the Intersects doesnt, with the same data. I can give you the ip address of the server is you want to try anything

Thank you for your help!

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!
