[Geoserver-users] WFS interesect filter

[Gregory G. <gre...@un...>]

Dear all,

With two colleagues, we are trying to intersect two features, like this example:

http://localhost:8080/geoserver/ows?&VERSION=1.0.0&SERVICE=WFS&REQUEST=GetFeature&TYPENAME=cities&Filter=<Filter>
<Intersect><PropertyName>Geometry</PropertyName><gml:Polygon><gml:outerBoundaryIs><gml:LinearRing>
<gml:coordinates>135.5329,34.6624 135.4921,34.8153 135.3673,34.7815 135.3800,34.6216 135.5361,34.6210 135.5329,34.6624</gml:coordinates></gml:LinearRing></gml:outerBoundaryIs></gml:Polygon></Intersect></Filter>

but instead of defining the <gml:coordinates> we want to call a second WFS GetFeature like that:

http://localhost:8080/geoserver/ows?&VERSION=1.0.0&SERVICE=WFS&REQUEST=GetFeature&TYPENAME=cities&Filter=<Filter>
<Intersect><PropertyName>Geometry</PropertyName><HTTP><Get onlineResource="http://sdi.unige.ch/arcgis/services/WFS_GDB/MapServer/WFSServer? request=GetFeature&version=1.0.0&srs=EPSG:4326&typename=WFS_GDB:river"/></HTTP></Intersect></Filter>

But unfortunately this does not work.

Did someone has an idea on how to do that and if it is possible?

Thanks in advance for the help

Regards

Greg
