Transformed Soil Adjusted Vegetation Index (TSAVI)

"The Transformed Soil Adjusted Vegetation Index (TSAVI) is a vegetation index that attempts to minimize soil brightness influences by assuming the soil line has an arbitrary slope and intercept.


    NIR = pixel values from the near-infrared band
    R = pixel values from the red band
    s = the soil line slope
    a = the soil line intercept
    X = an adjustment factor that is set to minimize soil noise
