Abstract :
This study investigates the presence of surface minerals at the Dexing Copper Mine (DCM) in China through a hyperspectral Hyperion image. The Hyperion image acquired in April 2009 was utilised to map the area through spectral characteristics of three different types of minerals. The classified image identifies the degree of oxidation linked to Fe-OH absorption features. An opportunity to analyse the effect of topography in the weathering and transportation patterns of different minerals was explored through overlaid SRTM DEM on the classified image.
