<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>

this is all possible, what I am missing is that I'd like to be able to

<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>

can do the geometry format conversions, is this right?</FONT></SPAN></DIV>

<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>
