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

world_country_polygon.json

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

world_country_line.json

1km/world_country_line.json

Note: The "type" attribute takes one of three values: inner, outer and disputed.

world_land_polygon

world_land_polygon.json

1km/world_land_polygon.json

world_road_line

world_road_line.json

1km/world_road_line.json

world_road_line_simpler.json

1km/world_road_line_simpler.json

world_road_line_simplest.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.

Filtered by scalerank:

s0/world_cities.json

s1/world_cities.json

s2/world_cities.json

Note: The label-text, dx, dy and text-anchor attributes are interpreted by mapshaper and our basemap generator.

usa_adm1_innerline

usa_adm1_innerline.json

1km/usa_adm1_innerline.json

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

usa_urban_polygon

usa_urban_polygon.json

1km/usa_urban_polygon.json

world_water_polygon

world_water_polygon.json

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.
