Building Part - Spatial object type

Definition: A BuildingPart is a sub-division of a Building that might be considered itself as a building.

Description: NOTE 1: A building part is homogeneous related to its physical, functional and temporal aspects.EXAMPLE: A building may be composed of two building parts having different heights above ground.

Attributes

Definition: 2D or 2.5D geometric representation.

Description: NOTE: Multiple representations of the geometry are possible (e.g. by surface and by point).

Multiplicity: 0...*

Stereotypes: voidable

Valuetype: BuildingGeometry2D

Definition: 3D geometric representation at level of detail (LoD) 1, consisting of the generalized representation of the outer boundary by vertical lateral surfaces and horizontal base polygons.

Multiplicity: 0...1

Valuetype: BuildingGeometry3DLoD1

Definition: 3D geometric representation at level of detail (LoD) 2, consisting of the generalized representation of the outer boundary by vertical lateral surfaces and a prototypical roof shape or cover (from a defined list of roof shapes).NOTE: The prototypical roof shapes come from a defined list of roof shapes, in City GML; this list is equivalent to the code list RoofTypeValue, provided in the extended2D profile (without the hyperbolic parabaloidal roof).

Multiplicity: 0...1

Valuetype: BuildingGeometry3DLoD2

Definition: 3D geometric representation at level of detail (LoD) 3, consisting of the detailed representation of the outer boundary (including protrusions, facade elements and window recesses) as well as of the roof shape (including dormers, chimneys).

Multiplicity: 0...1

Valuetype: BuildingGeometry3DLoD

Definition: 3D geometric representation at level of detail (LoD) 4, consisting of the detailed representation of the outer boundary (including protrusions, facade elements, and window recesses) as well as of the roof shape (including dormers, chimneys).

Description: NOTE: The LoD4 representation is equivalent to the LoD3 representation in core 3D application schema. The LoD 4 representation is more meaningful in extended 3D application schema, with the optional description of building interior.

Multiplicity: 0...1

Valuetype: BuildingGeometry3DLoD

Definition: Characteristic of the building that makes it generally of interest for mappings applications. The characteristic may be related to the physical aspect and/or to the function of the building.

Description: This attribute focuses on the physical aspect of the building; however, this physical aspect is often expressed as a function (e.g. stadium, silo, windmill); this attribute aims to fulfil mainly mapping purposes and addresses only specific, noticeable buildings.

Multiplicity: 0...*

Stereotypes: voidable

Valuetype: BuildingNatureValue

Definition: Activity hosted within the building. This attribute addresses mainly the buildings hosting human activities.

Description: NOTE: . This attribute aims to fulfill management requirements, such as computation of population or spatial pla
ing ; this classification aims to be exhaustive for the functional buildings hosting human activities.

Multiplicity: 0...*

Stereotypes: voidable

Valuetype: CurrentUse

Definition: Number of dwellings.

Description: A dwelling is a residential unit which may consist of one or several rooms designed for the occupation of households.NOTE: In the data sets including building units, a dwelling is a residential building unit or, only when that building has no building units, a residential building.EXAMPLES: a single building dwelling could be a detached or semi-detached house. A block of flats will contain multiple dwellings determined by the number of individual flats.

Multiplicity: 0...1

Stereotypes: voidable

Valuetype: Integer

Definition: Number of building units in the building. A BuildingUnit is a subdivision of Building with its own lockable access from the outside or from a common area (i.e. not from another BuildingUnit), which is atomic, functionally independent, and may be separately sold, rented out, inherited, etc.

Description: Building units are spatial objects aimed at subdividing buildings and/or building parts into smaller parts that are treated as seperate entities in daily life. A building unit is homogeneous, regarding management aspects.EXAMPLES: It may be e.g. an apartment in a condominium, a terraced house, or a shop inside a shopping arcade.NOTE 1: According to national regulations, a building unit may be a flat, a cellar, a garage or set of a flat, a cellar and a garage.NOTE 2: According to national regulation, a building that is one entity for daily life (typically, a single family house) may be considered as a Building composed of one BuildingUnit or as a Building composed of zero BuildingUnit.

Valuetype: DateOfEvent

Definition: Date of last major renovation.

Multiplicity: 0...1

Stereotypes: voidable

Valuetype: DateOfEvent

Definition: Vertically-constrained dimensional property consisting of an absolute measure referenced to a well-defined surface which is commonly taken as origin (geo? water level, etc.).

Description: Source: adapted from the definition given in the data specification of the theme Elevation.

Multiplicity: 0...*

Stereotypes: voidable

Valuetype: Elevation

Definition: Date and time at which this version of the spatial object was superseded or retired in the spatial data set.

Multiplicity: 0...1

Stereotypes: voidable

Valuetype: DateTime

Definition: Reference to an external information system containing any piece of information related to the spatial object.

Description: EXAMPLE 1: Reference to another spatial data set containing another view on buildings; the externalReference may be used for instance to ensure consistency between 2D and 3D representations of the same buildingsEXAMPLE 2: Reference to cadastral or dwelling register. The reference to this register may enable to find legal information related to the building, such as the owner(s) or valuation criteria (e.g. type of heating, toilet, kitchen)EXAMPLE 3: Reference to the system recording the building permits. The reference to the building permits may be used to find detailed information about the building physical and temporal aspects.

Multiplicity: 0...*

Stereotypes: voidable

Valuetype: ExternalReference

Definition: Height above ground.

Description: NOTE: height above ground may be defined as the difference between elevation at a low reference (ground level) and elevation as a high reference (e.g. roof level, top of construction)

Multiplicity: 0...*

Stereotypes: voidable

Valuetype: HeightAboveGround

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: Name of the construction.

Description: EXAMPLES: Big Ben, Eiffel Tower, Sacrada Familia
