TSARVI (Transformed Soil Atmospherically Resistant Index)


Calculation:

TSARVI = ( a_rb*( NIR - a_rb*RB - b_rb )) / ( RB + a_rb*NIR - a_rb*b_rb + 0.08*(1 + a_rb) )
with RB = R - gamma[B - R]

Characteristics:

Based on the subsitution of the blue channel by the red-blue channel,
adjusted by soil line (a_rb) and slope (b_rb).
limited range: -1<TSARVI<1,
