When using this method to compare different images, it should only be used on images that have been atmospherically corrected. PVI = (NIR - a*Red - b) / (sqrt(1 + a^2)) NIR = pixel values from the near-infrared band Red = pixel values from the red band a = slope of the soil line b = gradient of the soil line Using a space-delimited list, you will identify the NIR and red bands and enter the a and b values in the following order: NIR Red a b. For example, 4 3 a=0.3 b=0.5. This index outputs values between -1.0 and 1.0. Reference: Richardson, A. J. and C. L.
