Valutazione dinamica del fattore copertura del suolo (C-factor) della RUSLE attraverso immagini telerilevate.
A correlation analysis between mean Normalized Difference Vegetation Index (NDVI), derived from MODIS imagery time-series (2001-2016), and mean long-term cover management data derived from the C-factor map of the European Union, is here reported. The aim was to find out a model equation helpful to...
