Vector Statistical Unit - Spatial object type

Definition: Statistical unit represented as a vector geometry (point, line or surface).

INSPIRE Data Theme: Statistical Units - [INSPIRE Data Theme Statistical Units]

INSPIRE Application schema: Statistical Units Vector - [INSPIRE Application schema Statistical Units Vector]

Supertype of: Area Statistical Unit

Subtype of: Statistical Unit


Attributes

Definition: External object identifier of the spatial object.

Description: An external object identifier is a unique object identifier published by the responsible body, which may be used by external applications to reference the spatial object. The identifier is an identifier of the spatial object, not an identifier of the real-world phenomenon.

Multiplicity: 1

Valuetype: Identifier

Definition: Descriptive unique object identifier applied to spatial objects in a defined information theme.

Description: Some statistical units may be assigned multiple thematic identifiers.EXAMPLE: NUTS codes are thematic identifiers.

Note /* Vector statistical units with a reference geometry instance of GM_MultiSurface must be instances of the specialised class AreaStatisticalUnit. */


Associated objects - Mandatory

Definition: A geometrical representation for vector statistical units.

Description: Vector statistical units can have several representations depending on the context they are used for. It is adviced to produce at least one reference geometry.EXAMPLE1: A vector statistical units may be represented both by an area and a point geometry. Such point can be the center of gravity or a label location.EXAMPLE2: For mapping, different generalised representations of vector statistical units are required. These geometries depend on the visualisation scale.
