boundary
Contains administrative boundaries as linestrings (no maritime boundaries yet) as linestrings.
Until z7 Natural Earth data
is used after which OSM boundaries (boundary=administrative) are present from z8 to z14.
OSM data contains all 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 indicating the level of importance of this boundary. At low zoom levels the Natural Earth boundaries are mapped to the equivalent admin levels.
