Trouble rendering large multipolygons #2690

Author: TomH If you actually choose osmarender as the component instead of just typing it into the keywords then the bug will get sent to the right place... |

Author: osm[at]petschge.de I suspect that this is really a bug in the tiled design of tiles@home. If you were able to render the whole planet at once using osmarender the relation should render just fine. |
Author: HamishB more examples: It's in very large multipolygon relations (>10k nodes, split into 495 nodes per way). AFAICT JOSM's Validator doesn't find any problems. All looks good in the online Mapnik tiles, just the Osmarender tiles go funny. thanks, |
Author: rammer I did some poking around with this and it seems that the large multipolygons get rendered correctly if the osm file fed to osmarender contains all the members of the multipolygons that intersect the tile to be rendered. And therefore not all members of relation 445107 is included. If I open the same bounding box in josm and download all the members of that relation, save the data and using that render the same area I get a perfect render. So you need to somehow coax osmarender to recursively download all members of the multipolygons in the tile to be rendered. Using something like http://www.openstreetmap.org/api/0.6/relation/445107/full |

I found a problem with a multipolygon (id 46541256). This is a >8000 nodes forest properly rendered with mapnik, but not with osmarenderer.
