TASK 1: NORMALIZED DIFFERENCE VEGETATION

WebAs you will notice, values differ significantly. NDVI values lower than 0.2 indicate no vegetation, just soil. Negative values are either water or urban areas. The higher the NDVI values (the same stands for SAVI) the denser (and more healthy) the vegetation. But NDVI start saturating after the value of 0.7, while SAVI at this point is only 0.3. WebUsing the commonly used soil brightness index with a normalized difference snow index (NDSI) , NDSI was proposed by Xu and others based on the characteristics of the response of the image to soil in the red and green bands of visible light, which are opposite to those of vegetation and water bodies.
