this to various lists, so I'm sorry to those who are getting
duplicates.</FONT></SPAN></DIV>

<DIV><SPAN class=690332715-07102004><FONT face=Arial size=2>I'd like to beef
up my Mapserver applications with some geoprocessing functionality - buffers
at present, other functions will follow. For now I am playing with
PostGIS and having great sucess, IF my features are all stored in the
database.</FONT></SPAN></DIV>

<DIV><SPAN class=690332715-07102004><FONT face=Arial size=2>What I'd like to
be able to do though, is take a feature from WMS getFeatureInfo or WFS and be
able to buffer that. As a test of this, I took the GML from a
getFeatureInfo request and parsed it manually to be a WKT string.
Then used PostGIS to run the buffer. Apart from slight precision
differences, it appeared to be close to what PostGIS would have done with it's
own feature (the WMS request was done against the same feature through
MapServer). </FONT></SPAN></DIV>

confirmed this is all possible, what I am missing is that I'd like to be able
to </FONT></SPAN></DIV>
<DIV><SPAN class=690332715-07102004><FONT face=Arial size=2>a.. do the
conversion from GML to WKT with some script/library</FONT></SPAN></DIV>
<DIV><SPAN class=690332715-07102004><FONT face=Arial size=2>b.. do this with a
GML stream</FONT></SPAN></DIV>
<DIV><SPAN class=690332715-07102004><FONT face=Arial size=2>c.. ultimately do
this without PostGIS database dependancy.</FONT></SPAN></DIV>

<DIV><SPAN class=690332715-07102004><FONT face=Arial size=2>I figure that GEOS
can do the geometry format conversions, is this right?</FONT></SPAN></DIV>

a library for linux/windows that will let me talk to it with

<DIV><SPAN class=690332715-07102004><FONT face=Arial size=2>I'm prodding these
lists in hopes of finding out what else is going on out there in this
area. It would be fabulous if this was all built into Mapserver,
but from what I can tell, it's just a thought right
now. </FONT></SPAN></DIV>
