[OSM-talk] Country borders at zoom levels 7, 8, and 9 (Mapnik)

[Steve Chilton]

You might want to look at that particular one.
The change will bring boundaries tagged as admin_level=2 (national boundaries) in earlier.
The tagging for national borders should be as per wiki:
 
boundary=administrative <http://wiki.openstreetmap.org/index.php?title=Tag:boundary%3Dadministrative&action=edit> , admin_level <http://wiki.openstreetmap.org/index.php/Key:admin_level> =2 <http://wiki.openstreetmap.org/index.php?title=Tag:admin_level%3D2&action=edit>  marks country borders, such as the border between Austria and Germany. The names of the countries is specified through the tags "left:country", "right:country", if used on a linear way rather than an enclosed/area way.
 
This appears to be tagged as admin_level=4 - at least on the section I looked at just now.
 
Cheers
STEVE

	Here's an example:

	Glad to see this will be fixed by Wednesday! :)
	
	I'll double-check that everything works then too.

		Could you give a link to a suitable position to see this on the map?

		One possibility is that this way is the border of multiple regions and
		has a tag like:
		       admin_level="7;8"
		
		If so, this causes problems for the older osm2pgsql/mapnik code which
		running on the tile server at the moment. I plan to update to the trunk
		osm2pgsql code which should handle this better.
		
		A trac ticket does make it easier to keep a record of known issues.
