Admins

info

Overture Maps has announced the deprecation of the admins theme, to be replaced with a new divisions theme. As of the April 2024 release, divisions is available to users. Both admins and divisions will coexist for the next two releases (June and July). In the August 2024 release, admins will be removed from Overture Maps. We encourage you to begin the transition to divisions now.

Overview

The features in the Overture Maps admins theme describe named localities in the real world including settlements, cities, regions, provinces, and countries. The admins schema does not support the modeling of multiple geo-political views.

Key schema design choices

Clear country definitions. There are no gaps or overlaps at the country level admin_level=1 in order to support visualization, sectioning, and other mapping use cases, even in cases of disputed boundaries. Additionally, all countries have been assigned an ISO-3166-1 alpha-2 ISO country code. For some disputed areas and remote overseas territories, we have created custom ISO codes.

Admin feature types

  • locality describes a named and typically populated place. There are two sub-types:
    • administrative localities model countries and their hierarchical subdivisions. Each administrative locality has an administrative level indicating its level within a country. Attributes like driving side and default language are also available.
    • named localities model named places that are not part of a countries administrative hierarchy.
  • locality area adds land or maritime polygons to locality.
  • administrative boundary provides a boundary line of administrative localities. This feature allows for an easy display of country borders and administrative subdivisions within countries. Boundaries shared by different administrative localities are represented by one line. A maritime attribute supports filtering on boundaries located within seas or oceans.
