Method Study of Mineral Weight Information Extraction Based on Hyperion Hyperspectral Remote Sensing Data - The Region of Gannan as an Example
In this paper, the methods of extracting minerals weight information are studied based on hyperion hyperspectral remote sensing data, taking the region of Gannan area in Jiangxi as an example. After studying spectral angle mapping and matched filtering, the method has been developed which combines them to extract the weight information of minerals. The results show that this method can successfully apply and made spectral angle mapping integrate with matched filtering, combined their advantages and made up their shortcomings, and extract weight information of clay minerals accurately from the background image. Meanwhile, the location of all kinds of mineral and results of mineral mapping are consistent very well, reflecting the application feasibility of the method.
