Hi Brian,
I have the following connecting lines. When i used Polygonizer, it did
not give me a polygon. In these LineStrings, i have two linestrings
where one partly overlaps the other. Is that the reason?
Yes it is,
Sometimes, JTS assumes that input is valid or in this case "noded", to
avoid computation overhead.
If you use UnaryUnionOp to union your lines before polygonizing, you'll
get what you want,
Michaël
