Abstract

Abstract

The objective of this study is to enhance the absorption feature of hydroxyl and carbonate minerals, and to improve the precision of the minerals information extraction in the vegetation covered area. The linear mixing spectra of a pixel containing a hydroxyl/carbonate mineral, green and dry vegetation has been simulated. When a fixed wavelength range is considered, continuum removed absorption depths for diagnostic absorption features of three end-members show significantly linear relation. The vegetation corrected continuum depths (VCCD) model was established to detect hydroxyl or carbonate mineral, which was tested with hyperspectral data (Hyperion) collected at Huma in Xiaoxing'anling, China. Comparing the extracting mineral results and field samples of rock, it is found that the extracting minerals information correspond with that of the polished section of mineral, but the disturbance information is found in the river bed or along the road.
