3D Buildings (LOD 2.3 - Level of Detail 2.3) of Diekirch and Bastendorf
Description
The buildings are modeled on the basis of a photogrammetric exploitation of the aerial images of 2017.
The definition of the LOD 2.3 used includes a detailed modeling of the shape of the roofs (without details like skylights, chimneys, antennas, solar panels, ...) with a vertical projection to the ground. These data can be consulted in the 3D web viewer of geoportail.lu.
This type of building modeling is not yet available for the entire country. As part of the LiDAR pilot project in 2017, this building modeling was carried out over an area of 3 km2 (2 km2 in Diekirch and 1 km2 in Bastendorf).
The origin of these data restricts the separation of units at the building block level. The exploitation of aerial images for the modeling of 3D surfaces does not allow a distinction of units by cadastral parcels. (Eg terraced houses)
The data is available as CityGML files https://www.opengeospatial.org/standards/citygml, a standard format for exchanging 3D data.
Data not transformed into INSPIRE data model
