A study of the lithologic identification based on Hyperion and field spectra

A method for lithologic identification based on Hyperion data was developed and tested at Pulang and Songnuo of Zhongdian, Yunnan Province. Field spectra were turned into pixel of Hyperion. In this study, MNF was applied to Hyperion bands covering SWIR band and MNF band1 was used to identify lithology by density slicing. The mapping results were evaluated by the comparison with the geological maps. The results show that the method of turning field spectra into Hyperion pixel can effectively detect quartz diorite porphyrite and beschtauite in Zhongdian.
