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. 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.

disputed

Mark with 1 if the boundary is disputed.

Possible values:

  • 0
  • 1
