Enhanced Vegetation

Enhanced Vegetation Index (EVI) is a vegetation index that was developed to improve upon the Normalized Difference Vegetation Index (NDVI), particularly in areas with dense vegetation cover or in situations where atmospheric conditions may affect the quality of satellite imagery. EVI uses blue light to correct for the atmospheric influences and the canopy background signal, which can lead to more accurate assessments of vegetation health and density. Higher values indicate healthier and more dense vegetation. See Huete et al. (2002) for details. This layer is derived from ESA Sentinel-2 going back to late 2015 with frequent captures.
