Applying a data mining tool used regularly in digital soil mapping, this research focuses on the optimal inclusion of predictors for soil–landscape modeling by utilizing as wide of a pool of variables as possible. Predictor variables for digital soil mapping are often chosen on the basis of data availability and the researcher's expert knowledge. Predictor variables commonly overlooked include alternative analysis scales for land-surface derivatives and additional remote sensing products. For this study, a pool of 412 potential predictors was assembled, which included qualitative location classes, elevation, land-surface derivatives (with a wide range of analysis scales), hydrologic indicators, as well …

Soil sealing can be defined as the destruction or covering of soil by buildings, constructions and artificial layers completely or partly impermeable (asphalt, concrete, etc.) It is the most intense form of land consumption and is essentially an irreversible process. Soil is sealed when agricultural or other biologically land is taken into the built environment. It is also a continuing process within existing urban areas, especially where urban population and the density of built structures is increasing and residual inner-city green zones are reduced. The paper concerns the methodology for an estimation of the area of sealed soil using GIS …
