List of vegetation indices used in random forest classifications.

Indices	Formula
NDVI	(NIR − R)/(NIR + R)
EVI2	2.5 · (NIR − R)/(NIR + 2.4 · R + 1.0)

Red-edge EVI2	2.5 · (NIR–red edge)/(NIR + 2.4 · red edge + 1.0)
CIRE	NIR/red-edge-1
SWIR ratio	SWIR (B11)/SWIR (B12)
NDWI	(NIR–SWIR (B11))/(NIR + SWIR (B11))
