| Abstract: | The remote sensing technique has presented the most economical and effective method m the detection and assessment of the earthquake disaster. Detcting changes with both pre-earthquake and postearthquake remote-sensing images of the same area is key to gain earthquake damage information. Usingmultiple source remote sensing images such as SPOT5, FORMOSAT2, TM, ADS40 et al. This paper compares the change detection accuracy of three methods：pixel-level change detection method, post-classification comparison method and object-level change detection method, analyzes the merit and shortcoming of the existing method, in order to provide the instruction for studying the new and more effective change detction method. |
