The study of mineral information reorganization method was carried out by means of the airborne visible

light and near infrared and short-wave infrared imaging spectrometry (HyMap) data from Hami area of Xinjiang. By

analyzing spectral features of three kinds of familiar altered minerals (calcite, chlorite and muscovite) and using

the calibration of the remote sensing data and spectral reflectance retrieval, the authors employed spectral angle

mapper (SAM) to extract mineral information from the three kinds of altered minerals. With the mask technique, the

mineral distribution maps of calcite, chlorite and muscovite were compiled. In combination with the spectra of

spectral libraries, the authors also effectively carried out the verification.
