Normalized Difference Vegetation Index NDVI = (NIR ? Red)/(NIR + Red) Negative 4,3 5,4 8,4  
Normalized Difference Water Index--default NDWI = (Green ? NIR)/(Green + NIR)  Positive 2,5 3,5 3,8 monitor changes related to water content in water bodies, defined by McFeeters (1996).
Normalized Difference Water Index NDWI=(NIR ? SWIR)/(NIR +SWIR)       8A,11 monitor changes in water content of leaves, using near-infrared (NIR) and short-wave infrared (SWIR) wavelengths, proposed by Gao in 1996. 
Normalized Difference Water Index NDWI = (NIR - MIR) / (NIR + MIR)       8A,12 vegetation index sensitive to the water content of vegetation and is complementary to the NDVI. High NDWI values show a high water content of the vegetation.
Modified Normalized Difference Water Index MNDWI1 = (Green ? SWIR1)/(Green + SWIR1)
MNDWI2 = (Green ? SWIR2)/(Green + SWIR2)
