Processing
LiDAR processing
Australia-wide LiDAR processing and correction. Any sensor, any provider, any specification: corrected, cleaned, classified and ready to use.
We process and correct LiDAR from any provider, anywhere in Australia. Datum and height offsets, tilts and flight-line shifts are measured on stable ground and removed; then noise removal, ground and non-ground classification, vegetation and building classes, and tiling to your grid. Supplied classification is reviewed against the intended use and corrected where it falls short.
Further passes, or earlier surveys of the same area, can be co-registered and fused with GroundMap Fusion for more coverage and a point-by-point check.
- Registration, solved without GPS: 98.7 % of overlapping surface within 1 cm, across 44 laser scans (El Teniente underground study ).
Deliverables
- Classified point clouds (LAS 1.4 / LAZ, ASPRS classes)
- Correction report: offsets, tilts and flight-line shifts measured and removed
- Tiling, reprojection and datum transformation (GDA2020, AHD; MGA zones or your grid)
- Classification review report with exceptions
- Ground-point density and coverage summaries
Applications
- Preparing survey data for terrain and design models
- Bringing legacy surveys up to a current specification
- Vegetation and building extraction
