In this paper, the quality of HyMap data simulated with different payload indexes was evaluated in two aspects,namely,pre-processing and geoscience applications of the HyMap image data. In the aspect of simulated data pre-processing,three parameters were used to evaluate the quality of the simulated HyMap image data,i.e., average variance abnormality,histogram abnormality and correlation abnormality. In the aspect of geoscience application of the simulated HyMap data,the simulated HyMap image data were used to extract the alteration information of mineralization and mineral mapping,and the quality of simulated HyMap data with different payload indexes or with the same payload indexes but different scales was analyzed and evaluated according to the number and kinds of the information extracted and the precision of mineral mapping. Some good results have been achieved,and several valuable advices and suggestions are put forward for the study of HyMap sensor.
