Airborne Laser Scanning (ALS) has proven to be a helpful tool in landslides analysis. The purpose of the study was to determine the ability to identify areas of landslide activity at the commune scale (township scale) based on ALS data. Two researchers, who lacked knowledge concerning the study area, used point clouds to prepare a DEM, and then identified landslides as well as hazardous areas. The second part of the research team, who previously had performed detailed landslide mapping in the study area, had the task of verifying the outcomes of the first stage of research. Combined analysis of mistakes was performed and the capabilities and limitations of the method were established. Mistakes originating in either the vague parts of the point cloud DEM or terrain landslide mapping in forested areas were identified.
