Two generalization principles can be differentiated in soil geography: (1) point-to-area-generalization using different geostatistical methods and (2) soil survey in the landscape scale using soil catenae or soil landscape modelling. The point-to-area-generalization demands high investigation costs, however they are the base for investigations considering the spatial distribution of soil landscapes as well as for the determination of pedodiversity for practical use, e.g. precision farming. The deduction of soil catenae and/or soil associations considers the development of soil in combination with the landscape. Soil landscapes can be segregated and defined by comparable criteria. This is a prerequisite to account and regionalize soil present state, soil property changes and soil stress in a landscape context. Relationships between different scales are generalized using rules of aggregation (bottom-up principle) or disaggregation (top-down principle). Aggregation algorithm are useable in soil mapping as well as for soil management decisions. Examples for different applications, especially in respect to soil erosion research, are given.
