Application of multi-homed remote sensing image data fusion method in geology

With remote sensing imagery data merging theory, the application of optical remote sensing, thermal infrared remote sensing and microwave remote sensing satellite imagery in geology is studied. The multi-spectral data merging techniques, such as the fusion of the different types of remotely sensed data with other geo-data at the same remote sensor in different levels, the data merging of diverse SAR imagery data, HIS conversion, data merging of remotely sensed imagery with geophysical, geological, airborne electromagnetic data and so on, are analyzed. The results show that data merging technique has predominance to stand out linear structure, fault structure and landform characteristics in the aspect to extract geologic feature information.
