| Summary: | The paper presents the results that show possible use of unmanned aerial vehicle in the quadrocopter form factor (DJI Phantom 4 as an example) to evaluate soil erosion rates. Comparative analysis of the drone survey before and after using of the ground control points for three-dimensional digital elevation model (DEM) georeferencing has been performed. The use of four ground control points increased the accuracy of referencing to 100 times with decreasing of the height errors to 2–2.2 cm. In addition, comparison of the UAV-based model with the reference model has been carried out based on terrestrial laser scanning (TLS). The results prove the applicability of the method of evaluating gully erosion and accumulation rates by using UAV if the requirements for geodetic control are observed. |
