Predicting Soil Salt Content Over Partially Vegetated Surfaces Using Non-Negative Matrix Factorization

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2015
Remote sensing has been widely applied to map soil salinity in the last few decades. However, a notable decrease in the accuracy of soil salt content (SSC) predictions occurred when the soil surfaces were partially vegetated. To minimize the influence of
