Abstract In order to improve the extraction technology of mineral information from airborne hyperspectral and boost its application in geological engineering, the authors have completed several types of thematic maps based on CASI/SASI/TASI airborne hyperspectral data, including minerals species and abundance maps, as well as ore prospecting map from 2010 to 2015. All these maps were based on the mineral spectral feature analysis, hyperspectral image preprocessing, mineral information extraction, alteration anomaly information screening and regional prospecting prediction in mineralization belts of western China. A set of hyperspectral technique series was built to solve the problems of image preprocessing and minerals extraction and improve the airborne hyperspectral mapping to be more accurate and microcosmic. These investigations would help to build the foundation for hyperspectral applications in geological engineering and would be helpful to the traditional geological mapping and ore prospecting work.
