Tab.4 Vegetation indices and calculation formulas

植被指数	计算公式
RVI	$\frac{N I R}{R E D}$
EVI	$\frac{2.5 \times (N I R - R E D)}{N I R + 6 R E D - 7.5 B L U E + 1}$
ARVI	$\frac{N I R - (2 R E D - B L U E)}{N I R + (2 R E D - B L U E)}$
NDVI	$\frac{N I R - R E D}{N I R + R E D}$
MSAVI	$\frac{2 (N I R + 1) - \sqrt{2 {(N I R + 1)}^{2} - 8 (N I R - R E D)}}{2}$
OSAVI	$\frac{N I R - R E D}{N I R + R E D + 0.16}$
