[mapserver-users] is this possible or does this need to be a feature request

[Fred McDavid]

What I'm wanting to do is:

take a polygon from one layer, using that polygon and some function (in
this case, one that would add a "buffer" to the original polygon) come
up with a new polygon, then draw that polygon and/or use it to query
layers.

I'm wondering if there is presently a way to do this and, if not, what
obstacles (WRT design issues) would I face if I tried to make mapserver
and/or php-mapscript do this?

Regards,

Fred
