You either hack around with natural=land and layers (which is bad practice IMHO) or you use multipolygons. Trying to do both at once is just weird (and not really what that text is trying to say.) - - - - - - - - After the last round of discussions about how to tag multipolygons I left some tagged in different ways around my home city. I just checked the current state of their renders. 1) outer tagged with feature X & inner tagged with feature X - Works with osm2pgsql used on the main site (i.e. the mapnik layer) - Works with Osmarender 2) outer tagged with feature X & inner not tagged at all - Does not work with osm2pgsql used on the main site (i.e. the mapnik layer) - Works with Osmarender 3) outer tagged with feature X & inner tagged with feature Y - Does not work with osm2pgsql used on the main site (i.e. the mapnik layer) - Does not work with Osmarender So your first example doesn't show the islands because they are not having tags. I don't know why the island in the second example doesn't work. The relation and both the inner and outer polygon look OK. -- m.v.g., Cartinus _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk
