LiDAR (Ligth Detection And Ranging) is an innovative topographic laser beam measurement technique.

It allows dense sampling of the surface and produces a high precision topography (1 to 3 cm) including in forest areas.

The applications are varied and geared towards the needs of high precision topography and the characterization of forests:

We adapt our acquisition vector and sensor to the surface of the study area and to the resolution you need

UAV and VX 20 from Yellowscan

small surfaces (few km²) steep zones

Light aircraft and VUX 240 from Riegl

large surfaces bigger than 10km² et linear surveys

Survey design and survey

ground control points calibration

Point cloud generation and classification

DSM and DTM

Contour lines

Topographic map edition

In collaboration with a surveyor agency

Interpretation

We have a PHASE ONE high-resolution device and two lenses to adapt to the constraints of the terrain and produce orthomosaics up to 3cm resolution
