Soil Mapping Based on Globally Optimal Decision Trees and Digital Imitations of Traditional Approaches

ISPRS International Journal of Geo-Information, 2020
Most digital soil mapping (DSM) approaches aim at complete statistical model extraction. The value of the explicit rules of soil delineation formulated by soil-mapping experts is often underestimated.
