Airborne laser scanning
UAV LiDAR
Drone-mounted LiDAR, used on terrain and site types where imagery alone is not the appropriate method.
Overview
UAV LiDAR measures range directly with laser pulses, where photogrammetry derives the surface from imagery. Which of the two suits a site is a method decision taken per project, according to the terrain and the deliverable the scope calls for.
Applications
Vegetated terrain modelling
Terrain modelling on vegetated sites, within the agreed scope.
Pipeline & powerline corridors
Corridor terrain and clearance mapping in a single campaign.
Flood & drainage studies
Terrain models produced for hydraulic analysis.
SEC Capability
Integrated with SEC positioning
Trajectories controlled with GNSS ground infrastructure and validated against surveyed checkpoints.
Classification you can audit
Ground/non-ground classification reviewed by surveyors, not just algorithms.
Technology
Multi-return laser scanning
Multiple returns per pulse separate canopy from ground.
GNSS/IMU trajectory processing
Position and orientation are fused for every scan line.
Deliverables
- Classified point clouds
- Bare-earth digital terrain models
- Contours and corridor profiles
- LiDAR acquisition and QA reports
