Deliniation of Slope Units based on Scale and Resolution Invariant 3D Curvature Extraction

Finding slope units for a given watershed is an important task before analyzing landslide susceptibility. Usually, slope unit generation requires integration of several digital elevation model (DEM)-based outputs obtained from GIS and related hydrological software. Therefore, it is time consuming due to involved steps and compilation of various software outputs. In this paper a DEM-based, scale and resolution invariant, fully automatic method is proposed for creating slope units to be used in landslide susceptibility mapping.
