With Ganzhou area in Jiangxi province as the study area, this paper deals with the methods for extracting clay information from Hyperion data. Based on studying advantages and disadvantages of Spectral Angle Mapper (SAM) and Matched Filtering (MF), the authors have developed a method that combines SAM and MF to fix the information of all kinds of clay minerals in the study area. The results show that this method can be successfully used to Hyperion data and can totally integrate SAM with MF by combining their advantages, remedying their shortcomings, and accurately extracting the weight of information of clay minerals from the background image. In addition, the major parts of the weights of the locations and types of clay are consistent well with the sampling locations and the analytical results of the samples, suggesting the feasibility of this method.
