# Commission Regulation (EU) No 1089/2010 of 23 November 2010 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards interoperability of spatial data sets and services, Division: Attributes of the data type BuildingGeometry3DLoD

Extent: E+W+S+N.I.

Definition
Type
Voidability
geometryMultiSurface
Representation of the outer boundary by a MultiSurface, which may - in contrast to a solid representation - not be topologically clean. In particular, the ground surface may be missing.
GM_MultiSurface
geometrySolid
Representation of the outer boundary by a solid.
GM_Solid
terrainIntersection
Line or multi-line where the spatial object (Building, BuildingPart,.) touches the terrain representation.
GM_MultiCurve
voidable
horizontalGeometryEstimatedAccuracy
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.
Length
voidable
verticalGeometryEstimatedAccuracy
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.
Length
voidable
verticalGeometryReference3DBottom
Height level to which the lower height of the model (Z-value of the lower horizontal polygon) refers to.
