Airborne laser scanning data in landslide studies at the example of the Zbyszyce landslide (OuterCarpathians).
A b s t r a c t. The study is focused on an active landslide located on the right bank of the Dunajec Valley in
Zbyszyce. The potentials of application of the data derived from airborne laser scanning (ALS) in the context of an inventory of landslides has been presented. The ALS data used in this study covers the area of 40 km2 on the eastern side of Lake Roznowskie in the Carpathians. Scanning data were acquired on April 1, 2010, and the resulting cloud of points was used as the basis to generate the DTM with a resolution of 0,5 m. Geological interpretation of the data was conducted on the example of the largest and complex landslides in the study area located in the village Zbyszyce. Using different visualization techniques were able to determine extent of landslides and its internal morphological elements. Attempts to determine the degree of activity in different zones of the landslide have been also undertaken. Very good results were obtained in wooded areas, complementing the state of knowledge about this landslide.
