[geos-devel] Re: [GEOS] #368: TopologyException on Union of valid geometries.

[Martin Davis]

I took a quick look at this. It's a pretty typical robustness problem, 
which I guess the various heuristics currently in JTS don't handle well 
enough. Some more work on the snapping code might help to solve this. 
Failing that, a new approach is required.
