  "description": "The NDVI function creates a single band dataset that represents vegetation health, based on the difference between the red and near infrared bands.<div><br />NDVI is a standardized index allowing you to generate an image displaying greenness, also known as relative biomass. This index takes advantage of the contrast of characteristics between two bands from a multispectral raster dataset: the chlorophyll pigment absorption in the red band and the high reflectivity of plant material in the near-infrared (NIR) band. Extremely low or negative NDVI values represent areas with no vegetation at all, such as cloud, water, or snow. Very low values represent areas of little to no vegetation, such as concrete, rock, or bare soil. Moderate values represent areas of shrubs and grassland. High values represent forest areas and lush vegetation.<\/div>",
