Abstract :
In this study, we present a new vegetation index, the TDVI: transformed difference vegetation index. This index shows the same sensitivity as the soil adjusted vegetation index (SAVI) to the optical proprieties of bare soil subjacent to the cover. It does not saturate like NDVI and SAVI and it shows an excellent linearity as a function of the rate of vegetation cover.
