ABSTRACT
Geodetic measurements and monitoring are traditional methods of the observation of landslides, and slope movements processes in general. The precision of measurements is usually an important task, as well as the expended amount of time and money are important. It is not necessary to reach sub-centimetre precision in case of the regular monitoring of shallow landslide due to the effort to the evaluation of the whole landslide body. Unmanned aerial systems provide the great improvement in the efficiency of the process, and they also broaden possibilities in the visualization while the accuracy is still preserved on the suitable level. The contribution aims to present the current observation of shallow landslide, which has been monitored for seven years using geodetic measurements. Recently, the conventional surveying activities are complemented by the photogrammetric methods (Drone Pixy or Hexacopter). They allow monitoring of the slope stability and precise evaluation of the general shape of the landslide body including a volumetric analysis.

Keywords: Unmanned aerial vehicles, geodetic surveying, accuracy preservation, slope movement processes, photogrammetric evaluation.
