Abstract : Visible and near-infrared spectra of minerals and rocks have been measured and evaluated in terms of remote sensing applications. The authors conclude that there are some differences in the spectral behavior of different rock types in the visible and near-infrared. These differences are, however, difficult or impossible to use in a generalized remote sensing effort in which the composition of all rocks is to be mapped. Instead, this spectral region lends itself best to precise and particular applications, such as enhancing the visibility of a rock unit with a known and distinctive spectral signature, or enhancing the contrast between rock units, or between rocks and the vegetative background.
