Hi all,
I have succeeded in implementing your code on a polygon data set but with
point data I think there is probably an issue. There seem to be a
fundamental problem that I am not aware of. I have checked and rechecked the
templates, the mapfile and as for the code its the same. There is something
probably funny with the querybypoint as opposed to querybyshape? Any idea
Len (its kinda your brain child?)?
