Mapnik actually seems pretty good with multipolygons - all the issues I've seen are with areas in general, whether multipolygons or simple closed ways. There are some layering issues (http://trac.openstreetmap.org/ticket/3295) and of course boundaries aren't handled well (http://trac.openstreetmap.org/ticket/3069 http://trac.openstreetmap.org/ticket/3226). _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
