Representative average spectra of the 23 LCVF classes listed in Table 1, vertically offset for clarity. Many signatures (such as the clay-bearing series on the right) have subtle variations; others (such as the iron oxide-bearing species, A, L, W, F, G, on the left) have larger differences. The vertical dotted lines near 1.4 and 1.9 μ m indicate data fallout where saturated bands in the water vapor windows were eliminated, after atmospheric correction.
