Hi, Union should merge them unless they were close but not overlapping, then both polygons should be in the output. Could you share the case which doesn't work for you? Have in mind that the orientation and closure of Polygons has to be correct (so the input has to be valid) and that the the output of |

Hello,
I want to merge two polygon that should have one or several segment in common (or at least they should be very near). But they will never completely overlap. I tried union_ with the default strategy without any success, and didn't find anything about Union_ Strategy Concept. So I'm wondering how I should do that? If it's possible.
Thanks
