Abstract
Based on hyperspectral data mining techniques and characteristics of imaging spectrum, Hyperion satellite hyperspectral data are used to study the diagnosable spectral signatures and quantitatively extract the absorption spectral features of sandstone-hosted uranium deposits in northern China. In terms of information extraction approach and the processing method of extra-abundance data, we have adopted the quantitative method of radiance calibration, geometric correction and spectral mapping to study the geological features of uranium deposits. The prospect of hyperspectral data mining techniques for exploration and evaluation of uranium deposits has been discussed in the paper. Good results have been achieved in the practical application.
