SCAN performs works on the aerial survey of high-voltage lines using unique unmanned aerial vehicles of its own design. The survey of power lines’ corridors is carried out by UAV on the coordinates of the PTL towers and parameters of the survey corridor provided by the customer.After photogrammetric data processing, Agisoft Metashape performs a three-dimensional reconstruction of wires and PTL towers using special software.As a result, you receive the necessary materials for the subsequent evaluation of the HVL condition, the determination of the parameters and characteristics of HVL and tree and shrubbery vegetation in the corridors and within the protection zone.
