Table 2 Vegetation index and calculation formula

植被指数	计算公式
NDVI	$\frac{ρ_{n i r} - ρ_{r e d}}{ρ_{n i r} - ρ_{r e d}}$
EVI	$G \times \frac{ρ_{n i r} - ρ_{r e d}}{ρ_{n i r} + C_{1} ρ_{r e d} - C_{2} ρ_{b l u e} + L}$
TVI	$0.5 [120 (ρ_{n i r} - ρ_{g}) - 200 (ρ_{r e d} - ρ_{g r e e n})]$
RVI	$? \frac{ρ_{n i r}}{ρ_{r e d}}$
