Airborne Laser Scans
The Bavarian State Mapping Agency carries out area-wide airborne laser scanning campaigns at regular intervals and provides the point clouds for download via the open data portal:
The tiles can be downloaded with the following command:

Simulated Airborne Laser Scans
This dataset simulates airborne LiDAR scanning using the Helios++ toolkit and the high-quality LoD2 building models. To improve the neural network’s robustness in real-world conditions, noise and inter-building occlusions are deliberately included. The virtual sensor closely simulates the Leica HYPERION2+ system, with a survey flown at 400 m altitude by a virtual Cirrus SR22 aircraft. The training set encompasses 281,571 buildings and over 6.5 billion points from Munich, with an additional 10,000 buildings reserved for evaluation. Each building contains an average of 22,406 points. This dataset has been used for algorithm development in the PolyGNN project.
