Abstract: Being one of the main Characteres in strong radiation information, FIMS image are Showen the most sensitive information of alteration. This paper is focused on analyzing relationship between chemical components and spectral characteristics and discussing the mechanism of various geobodies＇s information from FIMS image by principle component analysis method, with an etawple of Temuerter, Altai Xinjiang. Finally a satisfactory result was given by spectral data processing, establishing the scientific basis for extraction of FIMS image processing.
