The concept of hyperspectral remote sensing began in the mid-80's and to this point has been used most widely by geologists for the mapping of minerals. Actual detection of materials is dependent on the spectral coverage, spectral resolution, and signal-to-noise of the spectrometer, the abundance of the material and the strength of absorption features for that material in the wavelength region measured.
Remote sensing spectral remote sensing for hyperspectral imagery and multispectral imagery analysis multispectral remote sensing involves the acquisition of visible, near infrared, and short-wave infrared images in several broad wavelength bands. Different materials reflect and absorb differently at different wavelengths.
However, a number of studies have demonstrated that broad band multispectral data are inadequate for the remote sensing of vegetation biochemical properties and that narrow band (high spectral resolution; usually a bandwidth of 10 nm or less) hyperspectral data are required (broge and mortensen, 2002).
