What was the discussion with the GEOS people like? Did they consider this to
be a bug in GEOS or a bug in PostGIS?
Ugh. Re-reading the thread, I realize I've misunderstood this. I
thought both issues were "in the same way", but I see now once was
geos and one was proj. Thus, I expected your cross post in the
followup covered it :-) So given that, I haven't actually contacted
the geos community specifically - unless they are represented on this
list.
Having said that, if you (or somebody else who actually knows the
PostGIS code well) would handle that contact, that would be great.
Given my lack of knowledge in the 10 or so stack frames between my
calling and the actual geos call, I fear I won't be able to answer
their follow-up questions in a good way :-)
I think a basic question of "how do we handle NaNs, -Inf/+Inf etc.?",
i.e. should GEOS error if it finds them or silently discard them could
be answered better on the main GEOS list. Obviously there is some
overlap here, but Martin Davis is probably the person with the best feel
for how this should work and I don't think he's on any of the PostGIS lists.
ATB,
Mark.
