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.

Aihe: Re: [mapserver-users] get polygons that contains a point
yes, this works wonderfully !
just wondering if this is a MapServer only feature of if it is part of
some OGC standard ....

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,
Josh

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
