The acronym LiDAR comes from the expression Light Detection and Ranging, which refers to a measurement technique based on the calculation of the time between the transmission and reception of a light signal. Based on the propagation speed of this signal, these systems provide accurate distance measurements that are then used to generate a three-dimensional (3D) point cloud of the assessed environment.
The LiDAR systems we use can transmit and capture between 100 000 and 600 000 points per second. These systems are entirely independent and equipped with GPS receivers and an inertial platform, allowing the precise geolocation of the measured points. They can be installed on an aircraft or on a moving vehicle such as a train or car.
