Conclusion

A partir de ces résultats nous pouvons conclure que n'importe quelle combinaison linéaire simple permet d’obtenir des indices de végétation tout aussi performants que les indices définis empiriquement, de plus des modèles plus avancés permettent d'obtenir des résultats plus performant et adaptés aux données récoltées.
Notons également que les indices NDVI = $\frac{n-r}{n+r}$, EnhancedVegetationIndex = $2.5*\frac{n-r}{n+6r-7.5b+1}$, EnhancedVegetationIndex2 = $2.4\frac{n-r}{n+r+1}$ et EnhancedVegetationIndex3 = $2.5\frac{n-r}{n+2.4r+1}$ sont très proche dans leurs formes et propose des performances très différentes après optimisation. On conviendra donc qu'il est plus important d'optimiser la forme de l'équation et les coefficients des bandes spectrales qu'une simple régression, c'est pourquoi nos indices générés automatiquement sont bien plus performants !
