Description

I have a topology exception when unioning two valid geomtries. Tested with geos 3.2.1 and geos svn (r2999).

Forget the error message :

comment:5 by strk, 11 years ago

I took a look at the geometries. Wow, you can't even see the second geometry while looking at the first one.

A.area: 276,625,072 B.area: 1,264

The first geometry (A) is a multipoligon, composed by 3 poligons. Unioning geometry B with each of the polygons in geometry A succeeds.

comment:6 by strk, 11 years ago

But then again... unioning A1B with A2B re-throws the robustness issue.

comment:7 by strk, 11 years ago

The problem is with 3rd polygon in A, which is a long and narrow ring. ST_Area returns 0 for it.. The non-noded intersection seems to be between the two wings of that "ring", or a snapped version of them.

Evidently I was wrong, JTS doesn't fail here. I'm attaching an updated test with expected result in it.

Now I see that the JTS result is an invalid polygon (self-intersecting). This is with JTS rev 386 (1.12+)

Milestone: 3.3.0GEOS Future

We'll wait for this to be fixed on the JTS side first.

comment:11 by strk, 10 years ago

Martin: is this case also fixed with current JTS ?
