Soil erosion assessment using proximal spectral reflectance in VIS-NIR-SWIR region in sample area of Calabria region (southern Italy)

The purpose of this study was to delineate eroded zones in a representative sample area of southern Italy, using SOM as a key indicators. To do that, was to test the use of laboratory VIS-NIRSWIR spectroscopy as fast and accurate technique to develop an empirical model for predicting SOM. A calibration model between SOM and soil spectral reflectance measurements was developed using a PLSR statistical method. (VISCARRA ROSSELL et alii, 2006). Finally, a geostatistical approach was employed to map spatial pattern of SOM, obtained from the laboratory measurements and the ones predicted from the soil spectral reflectance data, that consequently provide a characterize spatial variability of the soil erosion severity.
