Abstract

This paper illustrates the advantages of the hyperspectral data for sugar cane crop management. In 2002, a CASI airborne campaign and a ground measurement experiment were set up over sugar cane sites in Reunion Island. Early results indicate that LAI and biomass are significantly correlated with some narrow spectral bands in the NIR and that chemical leaf contents are well correlated with the PRI index. A multi-regression procedure was used to calculate transfer functions in order to produces thematic maps of LAI, biomass and nitrogen.
