Abstract
The automated derivation of landforms has become a necessity for quantitative analysis in geomorphology. Furthermore, the application of Geographic Information System technologies has become an important tool for data management and numerical data analysis for purposes of geomorphological mapping. The generation of model attributes as raster images for 28 layers and as drainage channel and divide networks based on digital elevation models takes place in the model kernel digital relief model. The classification of discrete attribute values on each data layer are processed by module REFAGN, the method used being variable. An interface to the program package statistical analysis system produces a second set of object attributes. This includes descriptive and spatial parameters derived from the unclassified attributes of each object. The principles of computer-aided analytical subdivision of a complex relief form are demonstrated for the example of the cuesta scarp in the Bingen/Aspisheim test area.
