Accuracy of the point cloud system	At a flight altitude of 120 m: Vertical accuracy: 3 cm (RMSE) Horizontal accuracy: 4 cm (RMSE) At a flight altitude of 300 m: Vertical accuracy: 5 cm (RMSE) Horizontal accuracy: 7.5 cm (RMSE)
Point cloud thickness	1.2 cm at 1σ (120 m nadir flight altitude) 2 cm at 1σ (300 m nadir flight altitude) Measured in linear scan mode, using control points on objects with 80% reflectivity, with neither point cloud optimisation nor sampling reduction enabled in DJI Terra. For 6σ, multiply the specified thickness by 6.
Combined horizontal field of view (two RGB mapping cameras)	107°, achieved by fusing images from two cameras with a 45° angle between their optical axes.
RGB Ground Sampling Distance (GSD)	Average value: 3 cm (300 m nadir flight altitude) For information on the detailed calculation methods, please refer to the user manual available on the Downloads page of the official DJI Zenmuse L3 website.

Detection range	700 m at 10 % reflectivity and 350 kHz 950 m at 10 % reflectivity and 100 kHz 2000 m at 80 % reflectivity and 100 kHz 1. Definition of range: the range is defined as the distance at which 50 % of the emitted laser pulses are detected. If a laser beam strikes more than one target, the total power of the laser transmitter is divided, reducing the potential range. 2. Test conditions: ambient light of 100 klx, within the central area of the FOV, using a flat target larger than the diameter of the laser beam, a perpendicular angle of incidence and atmospheric visibility of 23 km. 3. The maximum detection range is 900 m by default. For a greater range, please contact DJI Support or an authorised dealer.
Cable detection range	21.6 mm aluminium-braided cable with steel core: 300 m at 100 klx, 350 kHz 18.4 mm black PVC-insulated cable: 100 m at 100 klx, 350 kHz 1. Range definition: the distance at which a fully scanned section of cable in the mapping reaches a point density of 4 points per metre. 2. Test conditions: ambient light of 100 klx, atmospheric visibility of 23 km, the LiDAR’s field of view (FOV) centred on the cable and perpendicular to it, non-repetitive scanning mode, the drone flying along the cable at 15 m/s, and the cable is clean and not aged.
