LiDAR Flight

LiDAR (Light Detection and Ranging) technology allows drones to generate highly detailed 3D point clouds of both tree canopies and ground surfaces using laser pulses during flight.
This method is particularly advantageous in forestry surveys, as it can capture data even beneath dense vegetation.

Key Considerations for LiDAR Flights​

  • Flight speed: fly at a slower pace (around 5–8 m/s) to ensure sufficient data density.
  • IMU and RTK: accurate positioning and data alignment require regular IMU calibration and the use of RTK (or PPK) systems.

✅ Advantage: LiDAR enables precise mapping of the terrain beneath dense canopies — something often not achievable through photogrammetry.

⚠️ Note: Always verify that the correct return mode, sampling frequency, and flight altitude are configured. Otherwise, data collection may be incomplete.

⚠️ Important: When performing forestry surveys with a DJI LiDAR scanner, the recorded data must first be imported into DJI Terra and exported in .las format.
The resulting .las file can then be uploaded directly to the TreeDetect platform.
