Enhanced Vegetation Index
Calculates Enhanced Vegetation Index(EVI) from satellite images.
Description
Enhanced Vegetation Index (EVI) uses the NIR, red and blue channels to measure healthy vegetation, pixel by pixel with a simple algorithm. The EVI index is most appropriate in areas of dense canopy where the leaf area index (LAI) is high, the NDVI values can be improved by leveraging information in the blue wavelength. Information in this portion of the spectrum can help correct for soil background signals and atmospheric influences.

Values description: The range of values for the EVI is -1 to 1, where healthy vegetation generally falls between values of 0.20 to 0.80.
