Hyperspectral technology for geologic applications

Hyperspectral radiometers were developed and flown in aircraft and spacecraft early in the decade of the 1980s. Laboratory, field and aircraft experiments with hyperspectral remote sensing instruments at moderate ground spatial resolutions during the decade of the 1980s have now established the basis for hyperspectral imaging spectrometers with ground spatial resolutions of 5 metres or better and with spectral resolutions exceeding 200 wavelength bands. High spatial resolution hyperspectral imagers developed in the 1990s should permit identification and monitoring of environmental changes and verification of treaty compliance
