Contains administrative boundaries as linestrings (no maritime boundaries yet) as linestrings.
|
|
Until z7 [Natural Earth data](http://www.naturalearthdata.com/downloads/10m-cultural-vectors/10m-admin-0-countries/)
|
|
is used after which OSM boundaries ([`boundary=administrative`](http://wiki.openstreetmap.org/wiki/Tag:boundary%3Dadministrative)) are present from z8 to z14.
|
|
OSM data contains all [`admin_level`](http://wiki.openstreetmap.org/wiki/Tag:boundary%3Dadministrative#admin_level)
|
|
but for most styles it makes sense to just style `admin_level=2` and `admin_level=4`.
|
|
fields:
|
|
admin_level: |
|
|
OSM [admin_level](http://wiki.openstreetmap.org/wiki/Tag:boundary%3Dadministrative#admin_level)
|
|
indicating the level of importance of this boundary.
|
|
The `admin_level` corresponds to the lowest `admin_level`
|
|
the line participates in.
|
|
At low zoom levels the Natural Earth boundaries are mapped to the equivalent admin levels.
