DivisionArea

Division areas are polygon features 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.

Fields

Name	Type	Description
names(11)	Names	All known names by which the owning division is called
id	Id	A feature ID. This may be an ID associated with the Global Entity Reference System (GERS) if—and-only-if the feature represents an entity that is part of GERS.
bbox	bbox (optional)	An optional bounding box for the feature
geometry	geometry	The area covered by the division with which this area feature is associated. Allowed geometry types: MultiPolygon, Polygon
theme	"divisions"
type	"division_area"
version	FeatureVersion
sources[](10)	Sources (list, optional)	Information about the source data used to assemble the feature.
subtype	DivisionSubtype	A broad classification of the division this area belongs to (e.g., country, region, locality, etc.). This value is the same as the owning division's subtype. admin_level is required when subtype is one of: county, macrocounty, region, macroregion, dependency, country
class	AreaClass	A more specific classification of the division area than is provided by subtype.
is_land	boolean (optional)	Flag indicating whether or not the feature geometry represents the land-clipped, non-maritime boundary. The geometry can be used for map rendering, cartographic display, and similar purposes. strict=True At least one of is_land, is_territorial must be true
is_territorial	boolean (optional)	Flag indicating whether or not the feature geometry represents Overture's best approximation of the division's territorial boundary. For coastal places, this will tend to include the water area. The geometry can be used for data processing, reverse-geocoding, and similar purposes. strict=True At least one of is_land, is_territorial must be true
division_id	Id	Division ID of the parent division of this area. References Division (hierarchy, child of)
country	CountryCodeAlpha2	ISO 3166-1 alpha-2 country code of the division this area belongs to.
region	RegionCode (optional)	ISO 3166-2 principal subdivision code of the division this area belongs to.
admin_level	AdminLevel (optional)	Integer representing the division's position in its country's administrative hierarchy, where lower numbers correspond to higher level administrative units. admin_level is required when subtype is one of: county, macrocounty, region, macroregion, dependency, country

Constraints

• At least one of is_land, is_territorial must be true
• admin_level is required when subtype is one of: county, macrocounty, region, macroregion, dependency, country
