Ecosystem Mapping with NDVI

---

The Normalized Difference Vegetation Index (NDVI) assesses changes in plant health and vegetation density by quantifying vegetation greenness through red and near-infrared images obtained from the Landsat, Sentinel-2, Pléiades, and SPOT. The measurement is graded on a scale of +1 to -1, with vegetation increasing with increasing values. The lowest values of 0.1 and below represent barren, rocky, sandy areas or frozen wastelands. Moderate values indicate the presence of shrublands or grasslands, while the highest values correspond to temperate and tropical forests and rainforests.
