Formulation: $SAVI = \frac{(1 + L) \cdot (NIR - RED)}{(NIR + RED + L)}$, Use: To minimize soil brightness influences on NDVI when vegetation cover is low.

Formulation: $OSAVI = \frac{(NIR - RED)}{(NIR + RED + 0.16)}$, Use: A version of SAVI that assumes a standard soil brightness correction factor for all types of soil.

Formulation: $MNDWI = \frac{(GREEN - SWIR)}{(GREEN + SWIR)}$, Use: To enhance open water features while suppressing other types of features such as vegetation and soil.

Formulation: $GNDVI = \frac{(NIR - GREEN)}{(NIR + GREEN)}$, Use: To enhance the sensitivity of NDVI by using the green band instead of the red.

Formulation: $NDMI = \frac{(NIR - SWIR)}{(NIR + SWIR)}$, Use: To monitor vegetation moisture content.

Formulation: $MSAVI = \frac{2 \cdot NIR + 1 - \sqrt{(2 \cdot NIR + 1)^2 - 8 \cdot (NIR - RED)}}{2}$, Use: To improve the SAVI in areas with very sparse vegetation.

Formulation: $NDVI = \frac{(NIR - RED)}{(NIR + RED)}$, Use: To estimate vegetation density and health.

Formulation: $ARVI = \frac{(NIR - (2 \cdot RED - BLUE))}{(NIR + (2 \cdot RED - BLUE))}$, Use: To reduce atmospheric effects, especially for areas with high aerosol content.

Formulation: $EVI = G \cdot \frac{(NIR - RED)}{(NIR + C1 \cdot RED - C2 \cdot BLUE + L)}$, Use: To correct for atmospheric conditions and canopy background signals.
