Bare soil is indicator normali+ed index in the soil reflectance depending soil characteristics. Soil characters are combines color blue, red, rear infrared and short wae infrared. The bare soil areas, lands, egetation, with a background response is marked using in improed BSI. BSI has been calculated from formulas. -lease following below
