Quantification of Soil Variables in a Heterogeneous Soil Region with VIS-NIR-SWIR Data Using Different Statistical Sampling and Modeling Strategies

Estimation accuracies obtained for soil properties from spectroradiometer data markedly depend on the individual sample set. The choice of the statistical method to sample a calibration set and the extension of the multivariate modeling approach with …
