Abstract

This article highlights the ability of airborne laser scanning (ALS) to detect, map and quantify geomorphological processes in high alpine environments. Since 2001, ALS measurements have been carried out regularly at Hintereisferner (Ötztal Alps, Tyrol, Austria), resulting in a unique data record of 18 ALS flight campaigns. The quantifications of volumetric earth surface changes caused by dead-ice melting, fluvial erosion/deposition, rock-fall activity, gravitational displacements and permafrost degradation in glaciated, recently deglaciated and periglacial terrain is based on the analysis of ALS point clouds (vector data) to preserve the high quality of the data. The AA. present inter-annual, annual and perennial trends of geomorpho-dynamically induced topographic changes. Results are discussed considering high or low magnitudes time lapse rates and disturbing factors
