[Talk-ca] Re : admin_level of canadian cities

[Pierre Béland]

I suggest to keep node 30915641 where content is more accurate.  Tag state_capital is ok. But the tag admin_level=4 should be removed. And I dont know if capital=yes adds anything.


We should avoid to create duplicates of the tag admin_level and not confuse about where to place admin_level tags. 


Admin_level=4 refers to the province. It is placed in the boundary relation for Quebec province (as it is presenly).


Admin_level=8 refers to the municipality. It is presently in the node for Quebec city. wich is ok. Butwhen a boundary relation will be created for Quebec city, this admin_level tag will be moved to that boundary relation. 


Boundary relation :the node for Quebec city, 30915641, should be added to boundary relation for Quebec province with role .admin_centre

>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.

>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).

>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...)
