[Jts-topo-suite-user] Cleanup of the polygonized geometries

[jaume d. f. <ja...@pl...>]

Hi list,

I have a question regarding the Polygonizing. I've been writing complex 
topological processes based on the polygonizer results. But I often have 
to deal with situations in which the polygons created have very 
sharpened pieces because the coordinates of lines they were made of 
don't match exactly as I you can see in the pictures.

this is a zoom-to-extent view of the problem

this is a 400% zoom to the area marked in side the red circle in the 
picture above

this is a 2000% zoom which you can see what causes the problem

So, the pursued result is to obtain is a polygonizing like in the first 
picture. But at the end, the left-most polygon contains a very sharpened 
side in the top that confuses the subsequent process. My question is if 
it is possible to control this kind of things like by making some kind 
of snapping between lines, merging or polygonizing considering some sort 
of tolerance or any other suggestion you may have.

Thanks in advance!

Jaume.
