DescriptionNormalized Difference Vegetation Index (NDVI)
Indicator/Index/Metrics NDVI=NIRRedNIR+Red\text{NDVI} = \frac{\text{NIR} - \text{Red}}{\text{NIR} + \text{Red}}
where:
NIR\text{NIR} represents the spectral reflectance or radiance value in the near-infrared band, and Red\text{Red} represents the spectral reflectance or radiance value in the red band.
NoteThe NDVI value ranges from -1 to 1, where higher values indicate denser and healthier vegetation.
