Airborne 3D point cloud

The 3D point cloud was acquired with a high resolved 3D-LiDAR (RIEGL VQ-1560i) colocated with 2 cameras (RGB and Near-Infrared). We acquire the full wave form signal
from the laser scanner and provide multi-echo data after post-processing.

Additional data is associated to each 3D-point (x, y, z):
- Reflectance (intensity) at the laser wavelength (1064 nm, decibel (dB))
- Echo number
- Total number of echo returned from the laser pulse
- Acquisition viewing angle (degree)
- Point identification number
- GPS acquisition time (UTC)
- Point elevation (above sea level, meter)
- RGB + NIR (800 nm) (camera Digit Number, for display only)

The 3D-LiDAR calibration (geometry and radiometry) was achieved in lab and controlled during a first test-flight of the AI4GEO/CAMCATT campaign thanks to referenced
ground-targets deployed on the ONERA test field.

3D data characteristics:
- Point density: ~100 points/m²

The 3D point cloud is provided georeferenced in .LAZ format. Check the README file to get more information on the data organisation and characteristics.
