Overture Maps

Common schema definitions shared by building footprints and building parts

The Global Entity Reference System (GERS) is a universal framework for structuring and matching map data across systems.

Common schema definitions for places theme

Common schema definitions shared by all themes.

Addresses are geographic points used for locating businesses and individuals. The rules, fields, and fieldnames of an address can vary extensively between locations. We use a simplified schema to capture worldwide address points. This initial schema is largely based on the OpenAddresses (www.openaddresses.io) project. The address schema allows up to 5 "admin levels". Rather than have field names that apply across all countries, we provide an array called "address_levels" containing the necessary administrative levels for an address.

Common schema definitions the base theme (primarily from OSM)

Representation of the Earth's natural surfaces

A building is a man-made structure with a roof that exists permanently in one place. Buildings are compatible with GeoJSON Polygon features.

A single building part. Parts describe their shape and color and other properties. Each building part must contain the building with which it is associated.

Common schema definitions for divisions theme

A Place is a point representation of a real-world facility, service, or amenity. Place features are compatible with GeoJSON Point features.

Connectors create physical connections between segments. Connectors are compatible with GeoJSON Point features.

Segments are paths which can be traveled by people or things. Segments are compatible with GeoJSON LineString features.

Topographic representation of an underwater area, such as a part of the ocean floor.

Various features from OpenStreetMap such as bridges, airport runways, aerialways, or communication towers and lines.

Physical representations of land surfaces. Global land derived from the inverse of OSM Coastlines. Translates `natural` tags from OpenStreetMap.

Land use features from OpenStreetMap

Physical representations of inland and ocean marine surfaces. Translates `natural` and `waterway` tags from OpenStreetMap.

Divisions are recognized official or non-official organizations of people as seen from a given political perspective. Examples include countries, provinces, cities, towns, neighborhoods, etc.

Division areas are polygons that represent the land or maritime area covered by a division. Each division area belongs to a division which it references by ID, and for which the division area provides an area polygon. For ease of use, every division area repeats the subtype, names, country, and region properties of the division it belongs to.

Boundaries represent borders between divisions of the same subtype. Some boundaries may be disputed by the divisions on one or both sides.
