Hi Calin,
Thanx for your reply,
I tried tolerance 50 but still the same thing, query works only on =
polygon.
I also tried by plotting only points on the map, only one layer that =
means. :( still no luck.
here is def. of my layer in map file
# to disply postcode on map
LAYER # start of the "points" layer object
CONNECTIONTYPE postgis
NAME "points"
CONNECTION "host=3D34343 port=3D5432 user=3Dteest password=3Dtest =
dbname=3Dtest"
DATA "the_geom from points"
STATUS ON
TYPE POINT
METADATA=20
"DESCRIPTION" "DISTRICT"
"RESULT_FIELDS" "region"
END
CLASS
NAME "points"
COLOR 0 0 0
#OUTLINECOLOR 255 89 89
#SYMBOL 'circle'
SYMBOL 7
SIZE 8
END # end of class object
TOLERANCE 50
END # end of layer object
Many Thanks
Nida.

the query works fine...

Hi List,
I have a map file with some layers.=20
My query option works fine with all the polygon layers but it does =
not work for point.
For those points which are ploted on top of polygon, query display =
the polygon details,
and for the points outside the polygon, query display "no result =
found".
points layers is the top layer, so I dont understand why its =
querying the ploygon layer instead of points?
I really appreciate any input,
Many Thanks
Nida.
