Digital elevation model by the use of 3D laser scanner
The 3D representation of a given surface will be essential to any plans for a structural installation on that site or the calculation of risks (creep or subsidence).
A 3D representation will also facilitate the visualization of a given environment, even to the less expert eye.
In addition to the speed and exhaustiveness of measurements, the calculation of a digital land model from a 3D scan provides a level of detail which only this technology can deliver.
In just a few seconds, the device used can record over 1000 points per m² at a distance of up to 300 m. The result is a highly detailed and accurate matrix plot.
