At Géomog, drones are now an essential 3D capture tool for various surveying projects such as topographic surveys, quarry monitoring, volumetric calculations and various surveys. The outdoor 3D scanner creates high-precision images of buildings and roofs.
Using the high resolution images and photogrammetry process, we are able to generate a very high quality orthomosaic (large aerial image) and geo-referenced XYZ point cloud with precision spectra of less than 25 mm on the ground. The margin of error in calculating volumetry is 1%. The images and videos taken by the UAVs can also be used to inspect buildings at height and to monitor and track complex structures such as bridges, viaducts, dams, etc.
