What is NDVI?
NDVI is the most common vegetation index in remote sensing to measure healthy
vegetation. Normalized Difference Vegetation Index (NDVI) quantifies vegetation by
measuring the difference between near-infrared (which vegetation strongly reflects)
and red light (which vegetation absorbs). The result of this formula generates a value
between -1 and +1. When you have higher NDVI values, you have healthier vegetation.
When you have lower NDVI, you have less or no vegetation.
