The first important step is collecting valid data.
NOTE: To prepare the lidar data and create a LAS file, you need a GNSS base station. It is recommended, for easiest processing, to use the DJI D-RTK 2 Base Station. You can, however, use a CORS station or your own GNSS base station. You will need to download and install DJI Terra to prepare the LAS file (point cloud).
