This is the sort of thing that is most appropriate for PostGIS, it
really starts to get into the realm of GIS "analysis", which Mapserver
does NOT purport to do :-)
I would look into PostGIS' "Simple Features Specification for SQL
<http://www.opengis.org/docs/99-049.pdf>". It will do the buffering and
intersecting you describe.
However, it sounds like this doesn't need to happen interactively
through the web interface, if so you might explore a desktop GIS such as
Quantum GIS, uDig, etc.

i am a begainner in the mapserver World... i have completed
only one simple project just for viewing map, have no analysis.
now i contiue a project using php mapsript but now fall in
great problem.
i have shape file(.shp) containnig roads network. i have to
create a buffer area of this raods network arround 10 km.
using this buffer area i have to clip/select agricultural
land from another shape shape file.
i can create buffer using
$shp=roadlayer->getshape(-1,0);
$shp->buffer(10);
but it create buffer for only one road not the whole network...
buffer works at the shapeObj level, so you have to apply the buffer to
each shape, i.e.:
for(my $i=0; $i<$shapefile->{numshapes}; $i++) {
# apply buffer
# ...
}
plz give me the idea which process i have to follow to
complete my project..
my configuration:
mapserver 4.10(windows)
php mapscript
windows 2k
