Subject: Re: [geos-devel] Indexing question from a newbie
Guys,
One more question is, is it at all possible to construct quadtree and
strtree indices based on 3D point geometries? It seems you have to
supply the envelope of a geometry to the constructor function of both
the indices but can you construct envelopes of points?
