LiDAR.
Dense point cloud acquisition for millimetric topographic surveys and mapping under vegetation cover.
Dense point cloud acquisition for millimetric topographic surveys and mapping under vegetation cover.
Airborne LiDAR uses a high-frequency laser rangefinder to measure the exact distance between the drone and hundreds of thousands of ground points every second.
Result: an ultra-precise 3D point cloud revealing the exact terrain relief, even under vegetation — where photogrammetry is blind. Ideal for corridors, forests, rugged terrain.
LiDAR excels where optical methods are limited — under vegetation, in corridors, on linear infrastructure.
Complete inspection of electrical corridors: conductor/vegetation distance, clearance calculations.
Ground detection under dense canopy, tree height measurement, canopy density.
Rugged reliefs, inaccessible zones, hydraulic studies, flow modelling.
Revelation of hidden structures under vegetation, non-invasive surveys of historical sites.
Easement monitoring, subsidence detection, ground movements, intrusive vegetation.
Extracted volume calculation, extraction monitoring, pit face safety monitoring.
Latest-generation laser rangefinder integrated with M400 drone. Centimetric precision, high rate, extended range.
A raw point cloud is useless without expert processing. Our method guarantees directly usable deliverables.
Height, speed and overlap calculated according to terrain and target density (up to 1000 pts/m²).
Dynamic LiDAR calibration in flight, RTK GNSS base, vibration compensation.
Ground, vegetation, buildings, power lines separation via ASPRS classification algorithms.
Export in standard formats, adapted to your GIS/CAD tools. Cleaned DTM, classified cloud.
