Re: [HOT] Broken (multi)polygon cleanup

Hi Jochen Your focus on these problems more related to the softwares process is quite interesting and valuable. While I continue to focus on the Haiti south west peninsula after the Matthew hurricane landing in october 2016,  I looked today at multipolygon relations misuse. For Buildings with

Re: [HOT] Broken (multi)polygon cleanup
