[mapserver-users] GetFeatureInfo results: Search returned no results

[Rahkonen Jukka]

Hi,

Perhaps you do not hit the points? See tolerance and toleranceunits in http://mapserver.org/mapfile/layer.html and set tolerance to quite many pixels for eliminating the possibility that your click just does not hit the target.

If that does not help I would have another try by copying the data from PostGIS ínto shapefile and dublicating the layer. If GetFeatureInfo works with shapefile then the trouble must have something to do with communication with PostGIS.

I wonder why do you have layer status=OFF instead of ON.
