Photogrammetric surveys with drones are particularly useful in the design phase of large plants such as wind farms or photovoltaic plants. The digital terrain model (DTM/DEM/DSM) obtained through a photogrammetric process integrated by the use of ground control points, allows an easy elaboration of the architectural project. On the basis of requirements, it is possible to set the surveys in such a way as to obtain an accuracy (absolute error) in the order of 1-3 cm with a GSD (ground sampling distance) of 1-3 cm.

Our technological infrastructure in the cloud, allows us to process the output in a very short time and return: orthophotos, point cloud, DSM/DTM and contour lines.

Under certain conditions, we integrate or replace the survey with drones with the one carried out by "manned" aircraft with advantages in terms of cost and speed in obtaining the relevant authorizations.
