Vegetation indices and formulae (bands B: blue, G: green, R: red, RE: red-edge, NIR: near infra-red).

Vegetation Indices	Formula
1. Normalized Difference Vegetation Index (NDVI)	(NIR − R)/(NIR + R)
2. Green Leaf Index (GLI)	(2 × G − R − B)/(2 × G + R + B)
3. Enhanced Vegetation Index (EVI)	2.5 × (NIR − R)/(NIR + 6 × R − 7.5 × B + 1)
4. Soil Adjusted Vegetation index (SAVI)	(1 + L) × (NIR − R)/(NIR + R + 0.5)
5. Modified Soil Adjusted Vegetation Index (MSAVI)	0.5 × (2 × NIR + 1 − sqrt ((2 × NIR + 1)2 − 8 × (NIR − R)))
6. Transformed Chlorophyll Absorption in Reflectance Index (TCARI)	3 × ((RE − R) − 0.2 × (RE − G) × (RE/R))
7. Visible Atmospherically Resistance Index (VARI)	(G − R)/(G + R − B)
