L'indice de végétation amélioré (EVI) est généré à partir des bandes proche infrarouge, rouge et bleue de chaque scène. Sa valeur est comprise entre -1,0 et 1,0. Pour en savoir plus, consultez Huete et al. (2002). Ce produit est généré à partir des composites de réflectance de surface MODIS/006/MCD43A4.
