Taking Miaoershan district in Guangxi Province of South China as an example, the characteristics and the processing techniques of the airborne hyperspectral data are discussed in detail. A series of programs for strip_removing, registration between bands, tangent correction illumination calibration and relative reflectance calibration has been developed. On the basis of software ENVI (the Environment for Visualizing Images), a field spectral library in the study area has been set up and a method for geometric corrections with satisfactory mosaic images has been developed. Great achievements in some aspects such as pure pixel extraction, spectral unmixing, interpretation, silicified zones and other alteration zones are successfully delineated and specific uranium prospecting areas are proposed.
