Satellite Details
Description
NDSI detects snow and ice cover by exploiting the high reflectance of snow in green and very low reflectance in SWIR. Values above 0.4 typically indicate snow-covered surfaces. Used for snow cover mapping, glacier monitoring, and hydrological modeling for water resource management.
