Hi all,
How would I test if a given polygon intersects with one of the polygons
currently in a multypolygon geometry?
I tried the && operator but if I'm not mistaken it will test the given
polygon against the bounding box of the whole multipolygon geometry and
not each one individually.
Thanx in advance.
Hi,
I think you will have to explode your multipolyons into single
polygons to do that.
A multipolygon is considered by postgis as a single object, thus &&
and overlaps (or other operators) will work on all polygons composing
the multi.
You can use dump() to generate polygons out of multipolygon, then test
each individual polygon.
