Drone Survey & Photogrammetry

Oculus operates DJI Matrice 350 RTK for precision survey work and DJI Mavic 3 Enterprise for rapid site documentation. LiDAR payloads include the Zenmuse L2 (5-return, 240K pts/sec) and photogrammetry payloads include the Zenmuse P1 (45MP full-frame). All operations are conducted by CASA-certified remote pilots.

With PPK/RTK positioning, drone photogrammetry achieves horizontal accuracy of 2 to 3cm and vertical accuracy of 3 to 5cm without ground control points. With ground control, accuracy improves to sub-centimetre. The Zenmuse L2 aerial LiDAR achieves 4cm accuracy at 150m above ground level.

Drone LiDAR (Zenmuse L2) fires laser pulses that penetrate vegetation canopy to capture ground surfaces underneath. It works in any lighting conditions and produces clean terrain models. Drone photogrammetry (Zenmuse P1) uses overlapping photographs to reconstruct 3D surfaces. It produces higher-resolution visual outputs (orthomosaics) but cannot see through vegetation.

Standard deliverables include georeferenced orthomosaic imagery, digital surface model (DSM), digital terrain model (DTM), and 3D point cloud. Additional deliverables include contour plans, volumetric calculations (cut/fill), cross-sections, and 3D mesh models. Processing uses Agisoft Metashape Professional or Pix4Dmapper.

Yes. All Oculus drone operations are conducted by CASA-certified remote pilots holding current Remote Pilot Licences (RePL). Oculus holds aviation liability insurance and operates under a documented safety management system. We handle all CASA notifications and airspace approvals for each project.
