Potlatch 2 will only draw multipolygons which consist of 1 outer way and 1+ inner ways, and where the tags are on the outer way. This multipolygon has several outer ways so will not be rendered properly. You could call this a bug but, to be honest, if people are going to invent insanely complicated relation structures (aka "advanced multipolygons") and completely go against existing OSM tagging practice (putting way tags on relations), I feel no obligation to waste a week of my life supporting it. It would be an exceptionally complex one to fix, as you'd potentially need to load extra data from the server if all the outer ways weren't in the current bbox. Mapnik has much more processing power and an intermediate step (osm2pgsql) available to it. P1 doesn't do any special rendering of muitipolygons at all. I guess maybe we could teach P2 not to bother (P1-style) if there's more than one outer way... cheers Richard -- View this message in context: http://gis.638310.n2.nabble.com/Odd-Potlatch-2-rendering-tp5892790p5895083.html Sent from the Newbies mailing list archive at Nabble.com. _______________________________________________ newbies mailing list [email protected] http://lists.openstreetmap.org/listinfo/newbies
