Mehrnaz Neyestani; Fereydoon Sarmadian; Azam Jafari; Ali Keshavarzi

Volume 72, Issue 4 , March 2020, , Pages 1147-1166


  In digital soil mapping, soil characteristic and classes could be extracted truly by numerical and quantitative modelling. Hence, derived rules could be fitted to similar regions for achieving ruled relations on areas without soil information which is called as extrapolation. In the present study, achieving ...  Read More
