Hi Paul, 

are you saying that I should use ...

 

ISO value for admin_level (6 & 7 - actually what is used in the GeoBase
product), or

what is identified in the wiki (5 & 6)
http://wiki.openstreetmap.org/wiki/Admin_level 

 

Question mark!

 

Daniel

>From the wiki, those look consistent with what I’ve seen locally, although
naturally I can’t comment about Quebec.

Bonjour Norman,

 

ISO Level 7 (Upper municipality) refers to an administrative area like the
County of Peterborough (ON), while the ISO Level 6 (Municipal Regional)
refers to an administrative area like Eastern Townships in Québec (a group
of county - a level that exist only in Québec)

 

Regards,

Daniel

Can you give an example of a municipal regional or upper municipality?
Looking at the global usage, admin_level=5 is seldom used. I would think
that Municipal Regional would be 6 and upper municipality would be 7, but I
can’t really say without examples.

 

I would also suggest that these features in the .osm file not be closed –
just have the boundary, don’t handle it like lakes where you have multiple
areas you need to join where they cross tile bounds.

Bonjour again! 

Available administrative boundary will be included in the next release of
Canvec.osm.  From the wiki, here is the tagging values I'm going to use


Municipal Regional:  boundary=administrative; admin_level=5 
Upper municipality:  boundary=administrative; admin_level=6 
Municipality:        boundary=administrative; admin_level=8 

 <http://wiki.openstreetmap.org/wiki/Admin_level>
http://wiki.openstreetmap.org/wiki/Admin_level (Canada) 

 

Municipality admin_level=8 corresponds to gdf order in ISO standard. 
  
Municipal Regional Area and Upper Municipality (admin_level=5 and 6) are
different from what the ISO standard says (gdf order=6 and 7). Is someone
can confirm that admin_level=5 and 6 is really what is expected?

Thanks again
