INSPIRE - Annex III Theme Buildings - Building 3D

This dataset contains 3D and 2D buildings on the national territory of the Grand Duchy of Luxembourg in 2023.

The 3D buildings were created on the basis of aerial shots taken in the summer of 2023 (flight period: mid to late June, early July, late August and early September 2023; flight height: +/- 3700 m above ground) by photogrammetric restitution of roofs (RMSE in x, y and z ≤ 20 cm), followed by downward extrusion and texturing of the resulting 3D models of buildings with oblique shots.
Only roofs of buildings with a footprint greater than 20 m² were captured, taking into account superstructures (e.g. dormers) whose longest side exceeds 50 cm and whose volumetry exceeds 1 m³.

The 3D buildings correspond to LOD (Level of Detail) 2.2 classification.

This dataset has been harmonized according to the INSPIRE theme "Buildings" data specification.
