Capture
LiDAR capture
Airborne, drone, terrestrial, mobile and underground: any platform the site needs, specified by GroundMap and captured to that specification.
We specify the platform for the job: crewed aircraft for regions, drones for sites, terrestrial and mobile scanners for structures and corridors, handheld and SLAM systems underground.
Density, pass layout, look angles and control are planned before capture and recorded, and every capture is checked against that plan on delivery. Where one pass is not enough, more are flown or scanned and fused.
Aircraft and drone capture is flown by CASA-certified operators engaged for each project, to GroundMap's specification. GroundMap's own RePL and ReOC are being arranged.
Deliverables
- Capture plan and specification
- Calibrated point clouds, LAS 1.4 / LAZ / E57
- Trajectory, calibration and control reports
- Accuracy statement against independent control
Applications
- Mine sites, pits and underground workings
- Tunnels, corridors and structures
- Cities, sites and catchments
