This makes sense to me:
SELECT astext(GeomUnion(GeomFromText('POINT(-104 40)'),
GeomFromText('POINT(-105 40)')))"MULTIPOINT(-105 40,-104 40)" But this not so much:SELECT astext(GeomUnion(GeomFromText('POLYGON((-104 40,-104 40,-104
40,-104 40,-104 40))'),
GeomFromText('POLYGON((-105 40,-105 40,-105
40,-105 40,-105 0))')))
"GEOMETRYCOLLECTION EMPTY"
Is this a bug? Or is it supposed work this way? It used to be
different with Geos 2.2.1 (I assume this is a geos issue so I included
that mailing list).
