Description
The buildings are modeled on a photogrammetric use of the 2017 aerial images.
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. This data is available in the 3D web viewer of geoportail.lu.
Attention: Detailed building modeling is not available for the whole country!
Coverage
This type of building modeling is not yet available for the whole country. As part of the LiDAR pilot project in 2017 this modeling of buildings was carried out on an area of 3 km² (2 km² in Diekirch and 1 km² in Bastendorf).
Less detailed modelling (LOD 1) of the whole country is available here.
Resolution of buildings
The origin of this data restricts the separation of units at the building blocks. The use of aerial images for the modelling of 3D surfaces does not allow a distinction of units by cadastral plots. (E.g. terraced houses)
Data structure and formats
The data is available as CityGML https://www.opengeospatial.org/standards/citygml , a standard format for the exchange of 3D data.
