ARVI (Atmospherically Resistant Vegetation Index)


Calculation:

ARVI = (NIR - RHOrb) / (NIR + RHOrb)
<math>ARVI = \frac{NIR - RHOrb}{NIR + RHOrb}</math>
RHOrb = R - gamma (B - R)


Characteristics:

ratio-based index,
limited range: -1<ARVI<1,
gamma generally = 0.5 (default value) or 1 (depending on aerosols),
