ABSTRACT
We present GIS (Geographic Information System) based methods for a spatial evaluation of geometric and kinematic properties of hill slopes in hard-rock terrain. Besides digital elevation data, our system includes regional continuous data on geological structures that might, under certain conditions, act as potential sliding- and cutoff planes for rockslides. Our applications allow, for the first time, a rapid regional evaluation and classification of first-order geometrical and kinematical slope attributes in hard rock terrain. For the future development of quantitative landslide susceptibility maps with GIS-based slope data, hydrological and mechanical parameters derived from detailed field- and laboratory investigations are of major importance and will be integrated into the GIS-based expert systems.
