Making Better Soil Maps Using Models of Tangential Curvature
Modelling enables various sources of information to be integrated in a GIS. But actuality requires a methodology that can compare existing soils and ground cover information with natural descriptions of the land surface, identify errors, specify the limits of scale and definition, determine the effects of erosive processes and, finally, assemble a credible soil map. An algorithm is employed to describe the relationships between soils and landforms using models of tangential curvature that divide the land surface into two planes (bulges and depressions) which determine the distribution and concentration of materials, water and structural elements of the soil. The method places a certain soil type in a positive or negative relief element: where this correlation is broken, clarification is required.
