NDVI shows normal range of -1 to 1, water, clouds and snow have negative values they reflect more red than IR radiation. Rocks and soils are shows values “Zero” values some reflecting the colour Red and IR radiation only green vegetation has positive and high NDVI values. NDVI change values were extracted for the same pixels that were used for calibration. NDVI Values ranges between -0.33 to 0.03 Water Bodies, 0.03 to 0.19 Non Vegetation, 0.19 to 0.27 Low vegetation , 0.27 to 0.38 Medium Vegetation and 0.38 to 0.77 Dense Vegetation.
