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.
