How can soil classes within a soil map unit be disaggregated? To answer this question, a soil landscape-rule based approach was used to disaggregate the soil map units by exploiting information in the map legend and the map unit descriptions. The descripti...

Soil landscape inference model (SoLIM) maps soil type, not soil mapping units, under the assumption that soil properties are fairly homogeneous over a small spatial extent. Thus, typically it takes a raster-based approach which means that it divides the ar...

Six terrain attributes were subjected to K-means clustering performed in SAGA-GIS using the hill-climbing method (Rubin, 1967) using a terrain attribute combination of multiresolution valley bottom flatness, multiresolution ridgetop flatness, planform curv...
