Modeling Soil and Woody Vegetation in the Senegalese Sahel in the Context of Environmental Change

We have another interesting article about environmental change in the Sahel online. For this article, we used a Random Forest classifier and remote sensing products, to model a soil map in the Senegalese Sahel. If people are interested, I can put the R code online. Brandt, M.; Grau, T.; Mbow, C.; Samimi, C. Modeling Soil … Continue reading Modeling Soil and Woody Vegetation in the Senegalese Sahel in the Context of Environmental Change
