WebDec 1, 2024 · This algorithm also forms the basis for the MODIS binary snow cover product ( Riggs et al., 2006 ). It uses the NDSI, the normalized difference vegetation index (NDVI) and reflectance in green and near-infrared wavebands. For TM and ETM+ data, the NDSI is formulated as: (1)NDSI = ρ0.56–ρ1.65/ρ0.56 + ρ1.65 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 ).
