WebDec 16, 2024 · This is especially problematic when comparisons are being made across different soil types that may reflect different amounts of light in the red and near infrared wavelengths (i.e., soils with different brightness values).

WebThe Soil-Adjusted Vegetation Index (SAVI) is a vegetation index that attempts to minimize soil brightness influences using a soil-brightness correction facto... 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. greenhouse effect and global warming ppt
