UAV LiDAR survey

UAV LiDAR with DJI Zenmuse L2/L3 to capture bare-earth terrain under vegetation. Deliverables: classified LAS point clouds, DTM/DSM, contours and topographic maps.

UAV LiDAR Survey

UAV-borne LiDAR records multiple returns per pulse, so ground points can be captured beneath tree canopy, which photogrammetry cannot do. It is the method of choice for forested hills, road and power-line corridors, and canals.

Typical specifications [x]

Item Value
Platforms DJI M350 RTK / M400 RTK + Zenmuse L2 (L3)
Point density [x] pts/m² at [x] m AGL
Accuracy (manufacturer, L2 @150 m) Horizontal 5 cm, vertical 4 cm
Processing DJI Terra → ground classification (CloudCompare/Global Mapper)

Deliverables

  • LAS/LAZ point cloud classified to ASPRS classes (ground, vegetation, building…).
  • DTM, DSM, CHM (canopy height model), contour lines.
  • Topographic map in DWG/DGN; corridor profiles.
  • Point cloud viewing on WebGIS.

Applications

Road, irrigation and hydropower design · forestry (stand density, tree height) · landslides and flash floods · mining · archaeology under vegetation.
