Hi,
You do not want to use meters as tolerance units. Use pixels. The default is 3, try to increase it to 10 or something.
I did not find any point layer we use with GetFeatureInfo but this one works for polygon shapefile
LAYER
NAME "Natura2000"
STATUS ON
DATA "\Data\natura06_poly"
TYPE POLYGON
DUMP TRUE
UNITS METERS
SIZEUNITS PIXELS
TOLERANCE 3
HEADER "d:\data\template\natura_header.html"
TEMPLATE "d:\data\template\natura_template.html"
FOOTER "d:\data\template\natura_footer.html"
TOLERANCEUNITS PIXELS
METADATA

"gml_include_items" "all"
"wms_title" "Natura2000"
"wms_srs" "EPSG:2393 EPSG:3067 EPSG:4326"
END
CLASS
NAME "Natura2000"
STYLE

END
END
PROJECTION

END
END

Hi Rahkonen,
Tried giving Tolerance as 3 and it's units as meters , but it did not work. Also tried with the mapfile that has shapefile layer. The case is same.
Do you any other idea that can solve my problem. And if you have already worked on this can you please send a piece of code that works.
With Regards,
Neelima Emmani

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.
