Abstract: The road is the lifeline of relief after strong earthquakes, rapid and effective way to provide situation of disaster area can provide strong information support for distribution of earthquake emergency rescue force. Recognition of damaged road based on remote sensing image is difficult in the field of remote sensing earthquake emergency, but it has incomparable value for earthquake emergency. On the basis of summarizing and analyzing the characteristics of road image before and after earthquakes, this paper systematically introduces method of road extraction from remote sensing images. The process of building remote sensing seismic damage assessment is established, and the method of extracting and evaluating the road of remote sensing seismic damage is mainly described, and the shortage of remote sensing road extraction in earthquake emergency is analyzed. At last, the application of remote sensing technology in the extraction and evaluation of earthquake damage is also discussed.

Key words: Earthqauke road damage, Multi-source remote sensing, Earthquake emergency
