Our drones are equipped with the last 3d Laser scanner technology and provide reliable and accurate data for your project.
What is the LiDAR and how it works?
LiDAR for Light Detection and Ranging, it is an assembly of different modules capable of emitting a light (laser) and measuring its variations when it encounters an obstacle. These variations are transcribed into points that can be classified and represent at the end a point cloud that will be a 3D representation of our environment.
To perform the mapping, we will grid the area with our drones, above a defined perimeter. During the flight, the laser raises more than 100,000 points per second and is able to pierce the vegetation to reach the ground. Our drones and LiDAR are synchronized with an RTK GNSS Base Station who sends the GPS correction in real-time to keep a centimetric accuracy. In some cases, we process the GPS correction in post-flight using PPK technology.
With this method, we can generate Digital Elevation Model (DEM) but also Digital Terrain Model (DTM) because the laser and our software are able to classify the readings to make it appear only some object class in post processing, like trees or buildings for example.
From these point clouds, we can also extract other data, such as contours lines and we can realize orthomosaic plans, thanks to the photos captured during the flight. These data can be integrated into your professional software (GIS and autocad for example)

A question ? Contact us now !
Our system is able to follow in real time the drone evolutions and gives a preview of the future point cloud directly on our monitor screen. We can thus make decisions more quickly to improve data collection and also check that there is no blind area in the 3D plane and that all the data is consistent.
