Catalog of data layers
- These files are in GeoJSON format unless otherwise noted.
- These files use WGS84 coordinates unless otherwise noted.
- Polygon and line files inside the
1km
directory are simplified at around 1km resolution. - Polygon and line files outside the
1km
directory are unsimplified. - Most polygon and line files are derived from Collins-Bartholomew data (see the Sources section below).
world_country_polygon
1km/world_country_polygon.json
Note: Disputed territories are included with the country that has administrative control, with the exception of Crimea, which is included as a separate polygon with geoid 'CRM'.
world_country_line
Note: The "type" attribute takes one of three values: inner
, outer
and disputed
.
world_land_polygon
world_road_line
1km/world_road_line_simpler.json
1km/world_road_line_simplest.json
Note: The "simpler" files exclude "secondary" roads, and the "simplest" files exclude "primary" roads and retain only "motorway" roads. The primary, secondary and motorway designations come from Collins-Bartholomew.

Note: This layer contains internal U.S. state boundaries.

Sources
Collins-Bartholomew (CB
)
The full collection of Collins-Bartholomew Shapefiles can be found on the Graphics server. These files are updated several times a year, and are an excellent source for up-to-date administrative boundaries. The data is not detailed enough for mapping small areas.
Natural Earth (NA
)
We're using Natural Earth for city labels, because the scalerank
attribute is very useful for controlling the density of labels.
