Abstract: Landslides belong to the category of serious geohazard that is commonly found in different parts of the Earth. They are caused by natural as well as anthropogenic factors. Their occurrence has a significant impact on urbanisation and land use. The primary influence on landslide formation is a loss of vegetation, changes in climatic conditions and harmful human activity. In Central Europe, namely in Slovakia, there are several sites where there are localities with smaller or more massive landslides that may affect the land relief, limit the urban use of the land and cause material damage. Therefore there is necessary the systematic monitoring of these landslides. In recent years a modern trend in the geo-hazard monitoring is the use of unmanned aerial systems (UAS). Aerial photogrammetry with UAS is a new technology for monitoringof the objects on the earth surface, including landslides. One of the results of the UAS aerial photogrammetry is the point cloud. Its detail and accuracy are comparable to another modern method -terrestrial laser scanning TLS. Several scientific papers have demonstrated that a 3D model created from he point cloud obtained by processing of the UAS photogrammetry images is suitable for assessing changes in the surface of the ground. The aim of our research is long-term stage monitoring and verification ofthe land changes using UAS photogrammetry in selected locations in Slovakia. One of these sites is also a landslide in the cadastral area of the municipality of Nižná Myšľa, which falls into the Košice self-governing region, district Košice -okolie (Slovakia).
