Multi-criteria evaluation (MCE)

Analyzing landscape functions (e. g. soil erosion) different information (e. g. land use, gradient, rainfall) must be taken in consideration. Using scientific-based methods the potential, risk or existing conflicts can be calculated. Depending on the selected methodology and the available information / datasets multi-criteria evaluation (MCE) is a very powerful tool. Therefore a reduction of complex environmental factors into a cohesive spatial concept is necessary. Overlay-functions (raster or vector-based) in combination with evaluation or impact models can be used to calculate e. g. suitable areas for farming or settlement or to perform impact analyses (see Fig. 6.)
