Hyperspectral Alteration Information Extraction of Tangchi Geothermal Area in Eastern Liaoning, China

Abstract

To assist in the exploration of geothermal energy, Using remote sensing technology in eastern Liaoning Tang Chi geothermal mineral alteration information extraction, based on Tang Chi region of Hyperion satellite hyperspectral remote sensing image data, combined with hot spring Tang Chi region ground spectral information of the measured mineral samples alteration minerals, verification Tang Chi region alteration mineral spatial distribution and the relationship between the geothermal energy. The results show that most of the mineral alteration information extracted is the exploration of geothermal energy services.
