Topographic survey of 5000ha carried out by gyrocopter and aerial photogrammetry.

Autocad topographic plans made from MNS and orthophoto on a 5000ha area.

Results obtained from 30,000 aerial images taken by the company Artech’Drone.

Digital surface model, orthophoto and topographic maps

DSM orthophoto et plan topographique

Above are two example topographic maps on which appear: terrain topography, elevations cotations, slopes, ditches, vegetation, tracks, cadastre and all the useful informations for sizing and setting up a future wind farm.

Turnkey maps directly delivered to the design office in charge of the wind turbine installation project and the consolidation of agricultural plots up to date +7 upon receipt of the images.
