Attributes

Definition: Representation of the outer boundary by a Multi Surface, which may - in contrast to a solid representation - not be topologically clean. In particular, the ground surface may be missing.

Multiplicity: 0...1

Valuetype: GM_MultiSurface

Definition: Representation of the outer boundary by a solid.

Multiplicity: 0...1

Valuetype: GM_Solid

Definition: Line or multi-line where the spatial object (Building, BuildingPart, ...) touches the terrain representation.

Multiplicity: 0...1

Stereotypes: voidable

Valuetype: GM_MultiCurve

Definition: Height level to which the lower height of the model (Z-value of the lower horizontal polygon) refers to.

Description: EXAMPLE: generalGround, bottomOfConstruction.

Multiplicity: 0...1

Stereotypes: voidable

Valuetype: ElevationReferenceValue

Definition: The estimated absolute positional accuracy of the (X,Y) coordinates of the 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: The estimated absolute positional accuracy of the Z- coordinate of the 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
