[Talk-GB] place=village|town|city and admin_level tags

[Dave F]

Hi

I've been improving the count accuracy of place=village|town|city tags

I come across a few that requires clarification. Relations with 
place=village|town|city and various admin_level tags.

First, an overall Question:
Are there valid reasons for including place=village|town|city tags in 
boundary=administrative relations?

Breaking it down:

_admin_level=11

As far as I'm aware admin_level=11 doesn't apply in Britain.

https://wiki.openstreetmap.org/wiki/Tag:boundary%3Dadministrative#Table_1:_Countries_using_admin_level_3%E2%80%9310
(scroll to near the bottom of the table).

They don't have the boundary=administrative, so the admin_level tag has 
no meaning.

They appear to have been added by one contributor. Some of the polygons 
appear very rough.

I contacted him a couple of years ago. He didn't explain the 
admin_level=11 tag & was vague about the paid mapping.

I don't see these as adding quality to OSM & would be happy to see them 
removed.

_admin_level=10

These are mostly councils/parishes/Welsh communities but are they 
individual places? Most encompass multiple towns & villages.


_admin_level=8_

Only two. Birmingham & Lincoln.  I think the place tag should be removed.



On topic comments welcome
