This video will explain about the normalized difference vegetation index. Although there are several vegetation indices, one of the most widely used is the Normalized Difference Vegetation Index (NDVI). NDVI values range from +1.0 to -1.0. Areas of barren rock, sand, or snow usually show very low NDVI values (for example, 0.1 or less). Sparse vegetation such as shrubs and grasslands or senescing crops may result in moderate NDVI values (approximately 0.2 to 0.5). High NDVI values (approximately 0.6 to 0.9) correspond to dense vegetation such as that found in temperate and tropical forests or crops at their peak growth stage. • Thank you • The formula for NDVI is, • NDVI = (NIR-red) / (NIR+red) • Find me on Facebook : / teksdada • Find me on Instagram : / tekson1 • Find me on github : https://github.com/Tekson1
