Normalized Difference Vegetation Index (NDVI):
The Normalized Difference Vegetation Index (NDVI) is a numerical indicator that uses the Red(3) and Near-infrared(4) spectral bands. NDVI is highly associated with vegetation content. High NDVI values correspond to areas that reflect more in the near-infrared spectrum. Higher reflectance in the near-infrared correspond to denser and healthier vegetation
NDVI (Landsat 4-5) = (B4 – B3) / (B4 + B3)
