NDSI—ArcGIS Pro | Documentation
The Normalized Difference Snow Index (NDSI) is designed to use MODIS (band 4 and band 6) and Landsat TM (band 2 and band 5) for identification of snow cover while ignoring cloud cover.
Normalized Difference Snow Index | U.S. Geological Survey
The C2 NDSI science product is the normalized difference between spectral bands green (G) and the shortwave infrared (SWIR). The NDSI is particularly useful for separating snow from vegetation, soils, and lithology endmembers.
