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.

BuildingGeometry3DLoD1 |
|
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.
|
| geometry3DLoD2 |
BuildingGeometry3DLoD2 |
|
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).
|
| geometry3DLoD3 |
BuildingGeometry3DLoD |
|
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).
|
| geometry3DLoD4 |
BuildingGeometry3DLoD |
|
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.
