GVI - Fractional Vegetation

Fractional vegetation is essentially NDVI displayed as a fraction (or a percentage if the fractional vegetation values are multiplied by 100%). NDVI values less than or equal to .07 are set to 0.0 and NDVI values greater or equal to .57 are set to 1.0 (NDVI values between .07 and .57 increase linearly from 0.0 to 1.0 as fractional vegetation).
