El Índice de vegetación mejorado (EVI) se genera a partir de las bandas del infrarrojo cercano, el rojo y el azul de cada escena, y su valor varía de -1.0 a 1.0. Consulta Huete et al. (2002) para obtener más detalles. Este producto se genera a partir de los compuestos de reflectancia de superficie MODIS/006/MYD09GA.
