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.
