Calculation of the TSAVI vegetation index

Recommended Posts

Hi. I am working on a remote sensing project about land degradation. I want to calculate TSAVI using a Landsat-8 image but I can't find how the a and b (slope and intercept) parameters are calculated. I only know that the variable X=0.08 according to the litterature. Can someone help me?

TSAVI=(s(NIR-s*Red-a))/(a*NIR+Red-a*s+X*(1+s2))

    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
