Abstract The successful launch of ZY-1 02C satellite has filled the gap in the high resolution remote sensing satellite developed by China itself. Based on the characteristics of the satellite image and data quality,the authors took ZY-1 02C P/MS sensor data of Russia's Siberia as an example to interpret the region's geological and mineral resources information for the purpose of analyzing the data processing and data quality of P/MS image in combination with the United States Landsat ETM+ data of the region for data fusion. Four kinds of fusion methods, i.e., HSV,Brovery,Gramm-Schmidt and PCA fusion, were used for experimental comparison. The experimental results show that the image fused with Gramm-Schmidt method not only suffers from the least loss of spectral information but also has the best fusion effect,thus improving the spatial resolution of the fused image effectively. In other words, the precision of remote sensing geological interpretation is greatly improved by Gramm-Schmidt method. The results obtained by the authors can play an active role in further promoting the application of the domestic high resolution remote sensing satellites in China.
