Hi,
I posted the message below back in august, but have only recently had
a chance to look into this further. Here is a minimal test case that
triggers the assertion failure using Shapely. Below that I have
included details on the debugging I did and a patch that fixes the
issue for me (no idea
Yes, GeometryNoder uses true snap-rounding, whereas ST_Snaptogrid just
does vertex rounding. Snap-rounding is more complex and slower, but is
much more powerful in terms of increasing robustness. (In fact, as far
as I am aware, it's the only real solution to provide fully robust
noding using

I see. So the difference between the GeometryNoder with a PrecisionModel and
using ST_Snaptogrid from PostGIS on the input geometries is that the
GeometryNoder snaps all nodes which are created by the noding process as it
works?
This seems like an elegant solution t
