WebJul 16, 2024 · However, to delineate snow lines as we propose, a binary (snow/nonsnow) pixel classification is eventually inevitable, that is, to determine the snow cover outline. In this regard, for vegetation-free areas, NDSI, and spectral unmixing (using 50% fSCA threshold for snow/nonsnow pixel classification) yield similar results (Rittger et al., 2013 ). WebOverview.
