Re: [Jts-topo-suite-user] Polygonizer still crashes with large scale assemble even with improved precisionmodel

[Michaël M. <m.m...@or...>]

Hi Phil,

I don't know exactly what is the cause of the problem but I may have 
found a way to solve it.

Some segments of the dataset appears twice, but the polygonizer needs  a 
clean, noded linework as input.

To clean it, I used OpenJUMP

- Tools > Edit Geometry > Convert > Extract Segments (option="Make 
double segments unique")

- Tools > Edit Geometry > Convert > Polygonize

It will need more time to investigate why the error occurs though as the 
algorithm should not produce a NullPointerException in any case.

Regards,

Michaël
