I have two shapefiles containing polygons.
Can OGR derive an intersection of these two layers?
Nick,
The OGR commandline tools do not include anything to do this. You could
do it using the library or write a script in one of the supporting bindings
languages. The key method is OGRGeometry::Intersection() which when invoked
on one geometry with another geometry will return a new geometry which is
their intersection.

Note that this method depends on GDAL/OGR having been built against the GEOS
geometry library which really does the work.
Best regards,
