Ok, let me be more detailed. First of all, I'm not an expert on this, so correct me anyone if I'm wrong. Here in germany, we have the 16 Bundesländer (single: Bundesland) [1], which varies from large ones (e.g. Bayern/Bavaria) to exactly 3 "small areas", namely the cities: Bremen, Hamburg, Berlin. This is what admin_level 4 is about. I'm not 100% sure about admin_level 6, this would probably be larger cities like Munich (the wiki is talking about "district free cities"/"kreisfreie Stadt"). admin_level 8 would be a "small/smaller city". I personally wanted to render the southern part of Nürnberg, which would be probably admin_level 9 or even 10 (however, maposmatic couldn't find a proper admin_level anyway, so I did the selection "by hand"). At the end of the day, there is no one "right" admin_level, when you both want to support Berlin (population: 3.400.000) and also Betzenstein (population: 2500) :-) Regards, ULFL [1] http://en.wikipedia.org/wiki/States_of_Germany P.S: Might be a good idea to indicate on the webpage, that admin_level=xy is the criteria the server is searching for - I was pretty uncertain what the webpage was actually doing when searching for the boundary. _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
