[OSM-talk] Multipolygons in Mapnik
This question arise on the Romanian OSM list. We are trying to get multipolygons rendered in Mapnik and we are following the instructions on the Wiki page: http://wiki.openstreetmap.org/wiki/Relation:multipolygon. So we are trying with no tags on the inner way and the building is still not rendered in Mapnik (it is fine in Osmarender). The building is the one name 'AJOFM Huneadoara' from here: http://www.openstreetmap.org/?lat=45.881101lon=22.900908zoom=18layers=B000FTF . The interesting fact is that I used a different approach a couple of months ago (when direction of the way counted, and with tags on both ways) and those buildings are render just fine even now. When I tried to help our collegue with his building and applying the same rules that worked before I still have the same results (no hole rendered). What are we doing wrong? How should we tag the building to get rendered with Mapnik? Thanks, Ciprian ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
Re: [OSM-talk] Multipolygons in Mapnik
I second this. Buildings with holes don't get rendered correctly consistently.

hello list, Ciprian Talaba schrieb: What are we doing wrong? How should we tag the building to get rendered with Mapnik? i'm also expiriencing a strange behaviour on multipolygons. multipolygons that rendered perfectly are not working anymore from one moment to another, but then after some time they render correct magically without any changes to the data. i have the suspicion that this appeared to happen since mapnik is rendering data after a few hours instead of the old weekly renderer run. in all cases, parts of the multipolygons have been touched, but not all. maybe someone can second this thesis. if so, we should file a bug. frank ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

You are correct, the hourly diff imports can not handle the multipolygon relation properly. These will fix themselves after the weekly import each Wednesday. Any edit to the nodes or ways in the relation will probably break it again. Overall the benefits of the hourly import far outweigh the slight problems with the multipolygon handling. Feel free to raise a bug if you want. I'm sure someone will get around to fixing it eventually but I have other things to look at right now.
