WebThe Normalized Difference Vegetation Index takes into account the amount of near-infrared (NIR) reflected by plants. It is calculated by dividing the difference between the reflectances (Rho) in the near-infrared and red by the sum of the two. NDVI values typically range between negative one (surface water) and one (full, vibrant canopy). WebMay 27, 2024 · NDRE – On The Edge Of Red. The first two letters suggest that this index is similar to NDVI, while the latter two stand for Red Edge. This index is more sensitive to the edge between the red and near-infrared bands of light, which makes it a more accurate nitrogen-in-the-air detector than NDVI.
