L'indice de végétation par différence normalisée est généré à partir des bandes proche infrarouge et rouge de chaque scène, sous la forme (NIR - Red) / (NIR + Red), et sa valeur est comprise entre -1,0 et 1,0. Ce produit est généré à partir des composites de réflectance de surface MODIS/006/MYD09GA.
