The ZY1-02D satellite is the first hyperspectral operational satellite in China. To test the application ability of ZY1-02D hyperspectral loading data in geological and mineral survey, the authors identified lithologic and mineral information on the basis of data pre-processing, and the results were compared with GF-5 data. The application ability of the data was analyzed effectively in combination with the results of field survey. The results are as follows: the coincidence degree of ZY1-02D hyperspectral data reflectivity spectrum curve and geological body spectrum curve is high in shape, which can meet the requirements of rock and mineral information identification; through the identification of rock and mineral information in combination with the geological and mineral data of the study area, it is shown that the lithological information of marble, monzogranite, calcite and dolomite and alteration mineral information of chlorite and limonite are consistent with the measured results. The results show that the data has good recognition effect on the information of rocks and minerals, and can provide data guarantee for the application of hyperspectral technology in the field of geology and mineral exploration.
