“…The basic principle of the identification of eroded and accumulated (AC) soils is based on the assumption that the spectral reflectance of eroded or AC soils has different attributes than non-eroded (NE) "healthy" soils. These differences are caused by changes in the chemical and physical properties of the upper layer of soils due to the processes connected with soil removal, soil transportation and accumulation (Chabrillat et al, 2014;Chappell, Zobeck, & Brunner, 2005;Conforti et al, 2013;Demattê & Focht, 1999;Lin, Zhou, Wu, Zhu, & Dang, 2014;Schmid et al, 2012Schmid et al, , 2016Žížala, Zádorová, & Kapička, 2017). Soil properties affected by erosion processes that have a spectral response in soil spectra at the same time can be identified as spectral soil erosion indicators.…”
