Abstract For land management options, a sharp partitioning of areas is suitable. However, applied soil science usually provides integrated data and different information from identical sites and does not supply a partitioning in respect to all variables. In this paper, we describe a way for deriving reasonable partitioning of sites from multidimensional data sets by an integrated statistical approach: the clustering of different discrete field data. For this purpose, two separate work packages (WP) are suggested. In the first WP, sets of different data are standardize and discretize in order to get collocated data on predefined locations This step is precondition for further processing of multi-dimensional statistical analysis. The second WP leads from the different sets of collocated data to a map of partitions representing different soil units. Using an example of field data, we could show that cluster analysis works as a useful tool for site partitioning.
