Vegetation index mapping
Derives vegetation health, density, and phenology indicators (NDVI, EVI, SAVI) from red and NIR band ratios; good for crop monitoring, deforestation alerts, and land cover change detection.
Band-ratio indices from red (~660 nm) and NIR (~840 nm). NDVI saturates in dense canopies; EVI corrects for atmosphere and soil background noise. Implemented across the entire Landsat/Sentinel-2/MODIS fleet. Wikipedia: Normalized difference vegetation index
