Description :
This study describes a terrain analysis method that combines modeled and defined geomorphographic terrain attributes with detailed field knowledge and local mapping experience. 450 forest soil profiles were used to statistically analyze the correlation to soil properties. The result is a two-stage hierarchical terrain classification approach that provides a differentiated and satisfactory reproduction of characteristic terrain attributes in the primary landscape units. As field surveys show, modeled steep slopes, ridges, slope edges, convex and concave slope formations correlate well to local landform elements. Up to now, the results for mid slope modeling have been unsatisfactory. The complex morphographic terrain classification approach, described in this study, is a feasible spatial and hierarchical basis for decision-based prediction models.
