[mapserver-users] get polygons that contains a point

[Rahkonen Jukka]

Hi,
 
As Steve said, you can do it with WFS. Send the query below to http://demo.deegree.org/deegree-wfs/services with http POST and you will get back a country which contains the given point <gml:pos>3.988165755918471 47.70294862553225</gml:pos>  
Unfortunately using WFS is a bit tricky and there are still too much interoperability problems with different WFS servers and clients.

		In addition, the standard CGI mode=nquery will do this for you and you can craft WFS filters to do so as well.

		Hi Sebastian
		Take a look at the queryByPoint function found here
		http://mapserver.org/mapscript/php/index.html#layerobj 
		
		Hope this helps,

		Hi All
		
		I have a OGR Layer. Is there any service that I can use to retrieve all the polygons from that layer that contain a given point ? So in the request I add the coordinates and as response I get the polygons that own that point 
		
		thanks
