[mapserver-users] QueryByPoint

[ANDREW WOOLEY]

Folks,

I apologize if this has been asked before, but I can't seem to find any thing about it on the archives.

For some of my themes, the query works just fine.  However, for others, it doesn't work at all.  I have tried many different things to get it to work, but I can't understand the problem.  I have copied the mapfile layer definitions for one that works and just change the data pointer and it won't work.  I have tried lots of combinations and I have discovered that - for one theme - if I click on very large polygons, it works, but anything very small will not work.  The same holds true with lines - larger lines work - smaller ones don't. Does this make any sense to anyone?  I just can't figure it out.  I have adjusted my tolerance from 1 to 1000 and many places in between, but no avail.

Any suggestions would be appreciated.

Andrew
