Three practical guides to choose your capture, control and point cloud georeferencing methods.
What is the difference between photogrammetry and LiDAR?
Photogrammetry and LiDAR both produce 3D data, but their methods, costs and use cases differ strongly.

In photogrammetry, GCPs constrain the reconstruction. In LiDAR, they mostly control the navigation system accuracy.

Practical guides
Common searches around point clouds
These topics cover frequent needs: georeference a LAZ file, reproject a point cloud, change the EPSG of a LAS file or convert a point cloud to WGS84.
Georeference a LAZ file
Understand when to use GCPs and how to check residuals after adjustment.
Reproject a point cloud
Move from a source CRS to a target CRS so data fits GIS or surveying projects.
Change the EPSG of a LAS file
Prepare a file compatible with Lambert 93, RGF93, UTM, WGS84 or a project reference frame.
Merge LiDAR point clouds
Assemble several acquisitions while reducing coordinate, origin and scale offsets.
