Here in Utrecht I have drawn a building with a "courtyard". The inner polygon does not have any tags. * The hole shows OK in [EMAIL PROTECTED]/Osmarender http://tile.openstreetmap.nl/?zoom=17&lat=52.08396&lon=5.10485&layers=000000BF * The hole does not show in the osm2pgsql/Mapnik generated tiles from openstreetmap.org. http://tile.openstreetmap.nl/?zoom=17&lat=52.08396&lon=5.10485&layers=00000B0F * The hole shows OK in the osm2pgsql/Mapnik generated tiles from openstreetmap.nl. http://tile.openstreetmap.nl/?zoom=17&lat=52.08396&lon=5.10485&layers=B000000F I think openstreetmap.nl uses a newer version of osm2pgsql than the main site. If that is true than it is just a question of time till multipolygons defined as per wiki description will show OK on the main site too. A multipolygon with the same tags on inner and outer shows OK at all three: http://tile.openstreetmap.nl/?zoom=15&lat=52.05845&lon=5.16772&layers=000000BF http://tile.openstreetmap.nl/?zoom=15&lat=52.05845&lon=5.16772&layers=00000B0F http://tile.openstreetmap.nl/?zoom=15&lat=52.05845&lon=5.16772&layers=B000000F -- m.v.g., Cartinus _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk
