Application of Altered Mineral Information and Structure to Hyperspectral Remote Sensing Prospecting

Hyperspectral remote sensing alteration information extraction is one of the important methods of geological prospecting and altered minerals mapping.Based on the HyMap hyperspectral image simulation of spaceborne hyperspectral data,and using hyperspectral remote sensing technology including spectral characteristics analysis,noise reduction,end member extraction,altered mineral mapping contour,this paper studies the application of spaceborne hyperspectral remote sensing data to mineral prospecting,combined with the linear structure of the study area.Distribution of altered mineral assemblages extracted can be used as the target for further pre-investigation work.
