SPECTRAL APPLICATION IN SPECTRAL RECONSTRUCTION AND VALIDATION BASED ON HYPERSPECTRAL IMAGING DATA

The main roles of spectra in pre-processing of hyperspectral imaging data were studied for the spectral reconstruction and validation based on aero HyMap data in Eastern Tianshan Mountain. The spectra of both muscovite and kaolinite in the area were used to smooth the noise and pseudo-spectral features or enhance some spectral features in the processing of atmospheric correction. Furthermore, in order to ensure the spectral realities and reliabilities of hyperspectral imaging data, the authors used spectra of muscovite and calcite to validate the spectral features of hyperspectral imaging data on the basis of above processing.
