EVI

Enhanced Vegetation Index (EVI) is a remote sensing multispectral index that is used for obtaining extensive information on the condition, biomass, and growth of vegetation. It is especially applicable in the case of areas having a high amount of vegetation since some vegetation indexes like NDVI might get saturated at those places. The Enhanced Vegetation Index utilizes near-infrared (NIR), red, and blue spectral bands for increasing the vegetation signal while correcting any atmospheric disturbance and soil background influence. Data obtained through the EVI helps to detect variations in the development of crops, vegetation conditions, forestation, and ecosystems at various times of the year. The EVI is widely used in the fields of precision agriculture, forestry, environmental monitoring, land cover assessment, climatology studies, and vegetation mapping using GIS. With the help of EVI data acquired from satellite or aerial photography, one can conduct comparison between the vegetation conditions in different places and observe their changes over time.
