In the 1980’s a new type of remote sensing technology

so called imaging spectrometry

. had developed. In this paper

the concept of imaging spectrometry

its theoretical basis and analytical methods of extraction for spectral information have been discussed. Based upon extraction of spectral information for the gold-bearing alteration zone by Fine-split Infrared Multi-spectral Scanner （FIMS）

and data-processing of the 19-Band AMSS

Geoscan MKII AMSS and GER 64-Bahd imaging spectrometer

some methods of data-processing and analysing of Imaging Spectrometers Information had been tested and developed.The procedures are approximately included as follows: （1） Transformation of raw image to reflectance one; （2） Displaying of imaging spectral curves of imaging spectrometer; （3） The parameter-measuring of spectral absorption band; （4） The algorithm-matching spectra for a library of lab. spectra with spectra-extracted from the imaging spectrometers data each other
