Are there any gdal/geos based utility out there that do a topological union
between two sets of geometry (shape files)?
AFAIR, GEOSUnion is a topological union
// C API
g3 = GEOSUnion(g1, g2);
GEOS does not provide any Shapefile I/O features, but you can use OGR
[1] to read Shapefile and access geomtry objects.
