EVI: Enhanced Vegetation Index

In VegSpecIndex: Vegetation and Spectral Indices for Environmental Assessment

Enhanced Vegetation Index

Description

The Enhanced Vegetation Index (EVI) was designed to quantify vegetation greenness by the combination of NIR, Red, and Blue spectral bands. The extended formula of EVI includes the corrections for the atmospheric conditions and considers the effects from the canopy background. Similar to the NDVI, the values of EVI range from -1 to +1, with the range indicating healthy vegetation located between 0.2 and 0.8 (Lemenkova & Debeir, 2023).

Usage

EVI (NIR, RED, BLUE)

Arguments
