[Talk-ca] admin_level of canadian cities

[Andrew Lester]

Ahh, you’re absolutely correct. I hadn’t noticed that node. The one I was looking at is http://www.openstreetmap.org/browse/node/30915641, which isn’t part of any relations. One of these two “Quebec” nodes should probably be removed and the remaining one added to the provincial relation.

We should not confuse province and municipality levels.

 

Quebec city has admin_level=8. See  node description http://www.openstreetmap.org/browse/node/1781476959


Quebec province has admin_level=4. See  Administrative boundary relationhttp://www.openstreetmap.org/browse/relation/61549

As far as I can tell, the reason Quebec City is tagged as admin_level=4 is because it’s the capital of the province. As per your linked wiki page, provinces are admin_level=4. For any old non-capital city, they should be tagged admin_level=8. Keep in mind that admin_level=* is primarily intended for use on boundary ways and relations, not the place=* node. The usage of admin_level=*and capital=* on city nodes is part of a proposed feature covering capitals (http://wiki.openstreetmap.org/wiki/Proposed_features/capital). Contrary to what that proposal outlines, the common usage according to Taginfo (http://taginfo.openstreetmap.org/keys/capital#values) seems to be that capitals are tagged as capital=[admin level number] (ie. Quebec City would be tagged capital=4).

hi,

What do you suggest for "admin_level" of canadian cities, because i noticed difference between the official Canadian recommendation on Openstreetmap wiki (http://wiki.openstreetmap.org/wiki/Admin_level#10_admin_level_values_for_specific_countries) witch is suggesting LEVEL 8 ... whereas you can check LEVEL 4 for big cities in Canada on Opensstreetmap (Quebec City as instance...)

So ... do we adjust our admin_level according to the canadian section of openstreetmap's wiki?
Or do you suggest to keep on tracks on LEVEL 8 usage... and why?
