Asghar Rahmani; Fereydoon Sarmadian; Sayed Roholla Mousavi; Seyyed Erfan Khamoshi

Volume 73, Issue 1 , June 2020, , Pages 105-124


  Conventional soil mapping is related to High density sampling, affected by scale and expert knowledge So using of new data mining methods in digital soil properties mapping was the main aim of this study for resolving conventional soil survey problems. In this research, 62 surface soil samples based ...  Read More

The spatial extrapolation of soil great group by application of Random Forest in arid region of central Iran (Faryab-Kahnooj)

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
