LIDAR acquisition


web-LIDAR

In airborne mode, the recent application of the Lidar technology (Light Detection and Ranging) to topography and mapping provide high density digital terrain models (MNT) or surface (MNS) with great efficiency.

Lidar remote sensing is the only technique capable of simultaneously detecting the surface of the ground and vegetation. It then provides a DTM of the soil and a DSM of the canopy. A density of several points per m² is accessible.

This non-intrusive technique is particularly suitable for topographical surveys of heavily forested areas, uneven or difficult to access.
This technology coupled with decades of production and innovation in photogrammetry has allowed us to acquire skills from acquisition to  topographic drawings or high density 3D digital models.
A high resolution stereoscopic photographic coverage may be associated with the lidar survey to provide orthophoto.

 

Our LIDAR

APEI has a Leica ALS70HP lidar. These platforms can be installed on all airplanes. This gives us high availability and rapid implementation, in France or abroad.
