Three key techniques related to spectral feature extraction, spectral unmixing, ground-object identification and mapping are discussed based on the processing flow and algorithms of hyperspectral remote sensing mineral resource exploration. The software has been developed for hyperspectral remote sensing resource exploration based on IDL, which integrates the functions of remote sensing image feature analysis, image information extraction, end member extraction, mixed pixe｜ decomposition, alteration mineral mapping and mineralization prospect area analysis, etc. Meanwhile, such questions as the construction of spectral library, the deep exploration of resources based on hyperspectrum, the mechanism analysis of mineral spectral features and the high performance processing of hyperspectral remote sensing image are also discussed.
