Re: [Geotools-gt2-users] nonstandard polygon

[Oleksandr H. <guz...@gm...>]

Hi,

thank you Andrea and Larry for the suggestions. I decided to go with
shifting since when I split into multipolygon I get
a small gap  between the subpolygons, but in my case this is crucial, since
later I check whether a point belongs to the polygon.

thank you
