ارزیابی و بررسی تعمیم‌پذیری مدل استنباطی خاک- سرزمین (SoLIM) در نقشه‌برداری رقومی خاک با استفاده از مدل رقومی ارتفاع و مشتقات آن

Discrete Models of Spatial Variability (DMSV) have limitations for soil identification in traditional soil maps. New approaches, generally called digital soil mapping (DSM), using continuous methods (CMSV), try to predict soil classes or soil properties based on easily-available environmental variables. The objective of this study was to map the soil classes of the Borujen area, Chaharmahal-va-...
