Building Geometry2 D - Data type

Definition: This data types includes the geometry of the building and metadata information about which element of the building was captured and how.

INSPIRE Data Theme: Buildings - [INSPIRE Data Theme Buildings]

INSPIRE Application schema: Building Base - [INSPIRE Application schema Building Base]


Attributes

Definition: The estimated absolute positional accuracy of the Z coordinates of the building geometry, in the INSPIRE official Coordinate Reference System. Absolute positional accuracy is defined as the mean value of the positional uncertainties for a set of positions where the positional uncertainties are defined as the distance between a measured position and what is considered as the corresponding true position.

Description: NOTE: This mean value may come from quality measures on a homogeneous population of buildings or from an estimation based on the knowledge of the production processes and of their accuracy.

Multiplicity: 0...1

Stereotypes: voidable

Valuetype: Length

Definition: 2D or 2.5D geometric representation

Multiplicity: 1

Valuetype: GM_Object

Definition: The geometry to be taken into account by view services, for portrayal.

Description: NOTE 1: In case of multiple representation by point and by surface, it is generally recommended to provide the surface as reference geometry.NOTE 2: The geometric representation whose referenceGeometry is true may also be used preferably for spatial queries by download services (WFS) or by Geographical Information System (GIS).

Multiplicity: 1

Valuetype: Boolean

Definition: Element of the building that was captured by (X,Y) coordinates.

Multiplicity: 1

Valuetype: HorizontalGeometryReferenceValue

Definition: Element of the building that was captured by vertical coordinates.

Multiplicity: 0...1

Valuetype: ElevationReferenceValue

Definition: The estimated absolute positional accuracy of the (X,Y) coordinates of the building geometry, in the INSPIRE official Coordinate Reference System. Absolute positional accuracy is defined as the mean value of the positional uncertainties for a set of positions where the positional uncertainties are defined as the distance between a measured position and what is considered as the corresponding true position.

Description: NOTE: This mean value may come from quality measures on a homogeneous population of buildings or from an estimation based on the knowledge of the production processes and of their accuracy.

Multiplicity: 1

Stereotypes: voidable
