[jts-dev] Polygonizer - data preprocessing to speedup the process

["Jan Tosovsky" <j.tosovsky@xxxxxxxx>]

Dear All,

I use polygonizer to build polygons from separate line segments. When their
number is huge (e.g. 100k), building polygons takes forever.

Is there any recommended strategy to speedup the process? 

Could joining simple lines into multilines help? Isn't this done in
polygonizer anyway?

More RAM? Or rather supercomputer? ;-)

Thanks, Jan
