Sure, this is possible. A union can return any type of geometry, from GEOMETRYCOLLECTION EMPTY to POINT to anything else. If the result is a LINESTRING, then the union of the two geometries share a boundary. If it is in a GEOMETRYCOLLECTION, then there is a mixture of types in the same result, such as POINT and POLYGON parts. All these are possible, and not so strange when you look at them drawn out. -Mike _______________________________________________ Community mailing list Community@lists.gispython.org http://lists.gispython.org/mailman/listinfo/community
