Hi,
I am using Mapserver 5.0.2 with Openlayers.
I've a line layer (from mapserver) shown on my base map(google physical).
Now, when i click on a line, i want to show a pop using openlayers.
I am able to do this for a polygon layer. I send the lat,lon of the
point that is clicked and use the postgis query
"ST_Contains(topology,geomFromText('POINT(77.87117958068927
13.491965860913544)',-1))" to find the polygon (and fetch the polygon
specific data to show on pop up) and attach the Openlayers popup to the
point clicked.
I am not able to do this for a line layer as the postgis query doesn't
return anything.
I tried this query also,
"ST_Contains(topology,geomFromText('POINT(77.87117958068927
13.491965860913544)',-1)) AND
distance(topology,geomFromText('POINT(77.87117958068927
13.491965860913544)',-1)) <= 1" but it doesn't work.
Does any one know how to check if a point is a part of a line or if
there is any other way to show the pop up?
Thanks a lot for the help.
Regards,
Subha
