The wiki instructions for administrative boundaries are designed I think to help renderers at whatever point in time the instructions were written. Each boundary relation is meant to have the boundary=administrative tag and the correct admin level tag. Each way is also meant to have the boundary=administrative tag and the lowest value of admin_level (so a boundary which is a member of say admin level 4,5,6,8 relations would get 4). I have always assumed that the way tags are only there to make things easier for renderers as in theory it can also be determined from the relations the way is a member of. If it is possible, this carto switch might be a good time to make the relation tagged levels take priority and the way tags unnecessary for relation based boundaries (though perhaps still relevant for boundary ways that aren't in relations). I've spent quite a bit of time in the past trying to keep the GB boundary tags in line with the wiki documentation, though haven't bothered recently: http://www.loach.me.uk/osm/boundaries/misc.aspx Ed _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
