It is the complete point cloud treated with an automatic classification to distinguish vegetation, water, bridges and soil (Model Key Point). The points identified as “unclassified” correspond to elements of the on-ground (buildings, superstructures, cars, etc.) or points whose automatic processing did not allow their identification.
The point cloud was colorised using the 2018 vintage of the orthophotographs of the Metropolis. So these are not colors captured by the laser.
These data are available in LAZ format (LAS compressed) in 1 km² slabs. The total right-of-way exceeds 1 400 km². To decompress a.LAZ, it is possible to use the open source LASzip tool: http://laszip.org/
