I would like to add a function that takes an anonymous GEOMETRYCOLLECTION and returns something more structured: - a GEOMETRYCOLLECTION where the first element is a MULTLIPOLYGON, the second a MULTILINESTRING and the third a MULTIPOINT? - a tuple, with elements 'polygons', 'linestrings', 'points', each with one multi* of each? - a tuple, with elements 'polygons', 'linestrings', 'point', each with an array of singletons?
The key here is to provide a useful flat structure to pull info out of. Some information in the GEOMETRYCOLLECTION *will be lost*, (but that seems an acceptable price) Another approach, which might be simpler for users to grok would be: ST_CollectionAsMultiPolygon() returns just the polygon elements of a collection. ... etc ... Thoughts? P. _______________________________________________ postgis-users mailing list [email protected] http://postgis.refractions.net/mailman/listinfo/postgis-users
