Study On Spectral Application Of Interference Imaging Spectrometer

Hyperspectral data application for land cover and mineral analysis is discussed in this paper. Four main parts are included: Hyperspectral data preprocessing, Land cover classification using an endmember-based method, Target detection and mineral mapping using spectral unmixing.Hyperspectral data preprocessing is discussed, including radiation correction and atmospheric correction. The flying data is processed using this preprocessing method, and they get a credible reflectance image.A new method for land cover mapping, endmember-based identification and classification, is used to process the flying data. They get a satisfying classification result.The interesting targets (cars) are detected using BandMax and SAM. They get a satisfying detection result.Mineral mapping for the lunar interference imaging spectrometer is studied. Three steps for spectral unmixing are discussed. They process the hyperspectral image of the Cuprite derived by AVIRIS using the spectral unmixing method for mineral mapping. This method can be used in lunar hyperspectral image processing future.
