LiDAR surveys

What is LiDAR?

LiDAR (Light Detection and Ranging) is an active acquisition method generating a three-dimensional scene from tens of thousands light pulses emitted and received every second. Such a device mounted on a UAV opens up an enormous amount of opportunities previously unexplored. Our LiDAR sensors equipped with 32 lasers and an RGB camera can produce a geo-referenced AND colourized point cloud with astounding fidelity.

Our services

Structure modelization

Our LiDAR is equipped with an RGB camera which allows us to acquire colored point clouds and hence a colored 3D model of your structure.

DEM, DSM, contours and canopy height models

With 32 lasers and the possibility of low acquisition speed, our sensor can efficiently penetrate the canopy.


LiDAR's precision and efficiency will greatly reduce your volumetry costs. Acquisition is independant of environmental conditions, as opposed to photogrammetry techniques.

Quantification of waterway erosion

It is now possible to precisely quantify water erosion of waterways over time in order to chose appropriate solutions and to mesure their impact.

Worksite supervision

A coloured, 3D model of a worksite that is replicable over a given time interval is an invaluable asset to worksite managers.

Virtual inspections

You will now be able to safely inspect and measure defaults and cracks in your structure (rock walls, bridges, pylons) from a distance.

Advantages of LiDAR

Using a LiDAR provides many advantages, notably:

A direct measure of distances

Unlike photogrammetry, LiDAR uses a direct measurement of distances. LiDARs can work at night and on cloudy days.

Multiple points of return

Light pulses from LiDARs with multiple points of return means that a single laser beam can measure more than one feature (typically treetops and ground), yielding incredible efficiency.

Structure modelization

LiDAR can easily and quickly model structures with small transversal sections such as electric lines and pylons.
