I'm rewriting core PostGIS Topology function to speedup
topology population, with a focus on finding faces
_properly_ containing a point (having the point on the
interior, not on the boundary).
We currently have a topology.GetFaceByPoint function
which I'm tempted to re-use as a signature for the
improved function, but that function also allows
finding faces having the query point on the boundary,
which is NOT what I want.
Now the question is: would people really need the
current behavior of that function and if so, why ?
I fail to understand in which case would anyone want
to deal with a tolerance for finding faces, unless
they accept multiple faces as answer (a point on
a face boundary is ambiguous as to which face should
be returned).
So: do you use that function ? For what task ?
