DivisionBoundary

Boundaries represent borders between divisions of the same subtype.

Some boundaries may be disputed by the divisions on one or both sides.

Fields

Name	Type	Description
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	Boundary line or lines Allowed geometry types: LineString, MultiLineString
theme	"divisions"
type	"division_boundary"
version	FeatureVersion
sources[](7)	Sources (list, optional)	Information about the source data used to assemble the feature.
subtype	PlaceType	admin_level is required when subtype is one of: county, macrocounty, region, macroregion, dependency, country country is required when subtype ≠ country country is forbidden when subtype = country
class	BoundaryClass
is_land	boolean (optional)	A boolean to indicate 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 Exactly one of is_land, is_territorial must be true
is_territorial	boolean (optional)	A boolean to indicate whether or not the feature geometry represents Overture's best approximation of this place's maritime boundary. For coastal places, this would tend to include the water area. The geometry can be used for data processing, reverse-geocoding, and similar purposes. strict=True Exactly one of is_land, is_territorial must be true
division_ids	list<Id>	Identifies the two divisions to the left and right, respectively, of the boundary line. The left- and right-hand sides of the boundary are considered from the perspective of a person standing on the line facing in the direction in which the geometry is oriented, i.e. facing toward the end of the line. The first array element is the Overture ID of the left division. The second element is the Overture ID of the right division. References Division (boundary of) Minimum length: 2 Maximum length: 2 All items must be unique. (UniqueItemsConstraint)
country	CountryCodeAlpha2 (optional)	ISO 3166-1 alpha-2 country code of the country or country-like entity that both sides of the boundary share. This property will be present on boundaries between two regions, counties, or similar entities within the same country, but will not be present on boundaries between two countries or country-like entities. country is required when subtype ≠ country country is forbidden when subtype = country
region	RegionCode (optional)	ISO 3166-2 principal subdivision code of the subdivision-like entity that both sides of the boundary share. This property will be present on boundaries between two counties, localadmins or similar entities within the same principal subdivision, but will not be present on boundaries between different principal subdivisions or countries.
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
is_disputed	boolean (optional)	Indicator if there are entities disputing this division boundary. Information about entities disputing this boundary should be included in perspectives property. This property should also be true if boundary between two entities is unclear and this is "best guess". So having it true and no perspectives gives map creators reason not to fully trust the boundary, but use it if they have no other. strict=True
perspectives(2)	Perspectives (optional)	Political perspectives from which this division boundary is considered to be an accurate representation. If this property is absent, then this boundary is not known to be disputed from any political perspective. Consequently, there is only one boundary feature representing the entire real world entity. If this property is present, it means the boundary represents one of several alternative perspectives on the same real-world entity. There are two modes of perspective: 1. accepted_by means the representation of the boundary is accepted by the listed entities and would be included on a map drawn from their perspective. 2. disputed_by means the representation of the boundary is disputed by the listed entities and would be excluded from a map drawn from their perspective. When drawing a map from the perspective of a given country, one would start by gathering all the undisputed boundary (with no perspectives property), and then adding to that first all boundary explicitly accepted by the country, and second all boundary not explicitly disputed by the country.
