[Qgis-user] [Qgis-community-team] 3D view of LIDAR data city of boulder

[Saber Razmjooei]

I am not sure about the licensing of the data.

For mesh layer, there are already some datasets for test suite, which
should be good for documentation too:
https://github.com/lutraconsulting/MDAL/tree/master/tests/data

Kind regards
Saber
