Replying to [comment:4 dannytoone]:
> Just gave it a runthrough on my dataset, and with the exception of a
stack overflow error (fixed by increasing the stack size through `-Xss`),
it ran flawlessly. I fully expected to see a bunch of exceptions, but it
handled them all really well. Visually I can't find any flaws in the
result.
Excellent!
> Not sure if it would be useful to find a way to get you this dataset for
exploring the behavior around topology exceptions that are handled
internally. I know for a fact that this same dataset will reproduce the
error linked above in the postgis tracker.
That's fine. We are using some of the data from your synthetic data
generator as part of the OverlayNG robustness tests. Given the success of
your testing, I think we can call this good, and you can wait for
OverlayNG to land in GEOS.
