Landslide types identified along carbonate cliffs using LiDAR-based DTM imagery – examples from the Vinodol Valley, Croatia

This paper presents possibilities for landslide identification and mapping along the carbonate cliffs, on the basis of the visual interpretation of high resolution (HR) airborne LiDAR (Light Detection and Ranging) imagery. The study was performed for the carbonate cliffs (2.12 km2) located in the Vinodol Valley, Croatia. An airborne bare-earth LiDAR Digital Terrain Model of 1 m resolution was created for the study area in March 2012. Seven different topographic datasets were derived from DTM and were visually interpreted for topographic signatures specific for landslides. Totally 118 chutes are identified along the cliffs, representing the areas for rock fall initiation. Also, 25 rock irregular slides, and two rock slope deformations were identified directly from the LiDAR imagery. For several identified accumulations of rock material is considered that they represent accumulations of rock avalanches.
