Enhanced Vegetation Index
The Enhanced Vegetation Index (EVI) is a satellite-derived measurement used to assess vegetation health and density. It improves upon the traditional Normalized Difference Vegetation Index (NDVI) by minimizing atmospheric interference and soil background effects. EVI is particularly useful in areas with dense vegetation, providing more accurate data for monitoring plant growth and land cover changes.
EVI is calculated using reflectance values from specific wavelengths of light, particularly in the red and near-infrared regions. This index is widely used in environmental studies, agriculture, and forestry to track seasonal changes in vegetation and to support sustainable land management practices.
