[mapserver-users] ENC: Openlayers Identify Problem

[Lime, Steve D (DNR)]

Looking at the URL it seems to be operating in image coordinates which is fine but there's no image size passed (nor one defined in the mapfile) so my guess
is that MapServer can't turn that click into a real map coordinate. Try adding the imgsize variable to your query call.

Hello all,

I´m from Brasil and i have a problem with the openlayers identify my query its perfect in the mapfile and the layer file but the query result :msQueryByPoint(): Search returned no results. No matching record(s) found.My url is : http://localhost/cgi-bin/mapserv.exe?img.x=762&img.y=433&mode=query&layer=gtile_topodata&map=C:/var/webmapit/mapserver.d/mapfiles/users/sntgeo/sntgeo-map_004.map&imgext=-104.42206737491+-39.398253504337+-2.9560446250874+11.398253504337

What is the problem?
