Abstract:Methods and techonlogy of faults ertracton and identification have important values both for applications and research works. Accompanying with rapid development of temote sensing and related technologies, the remote sensing interpretation methods of faults have also made great progress. In this paper, the necessity and interpretation marks of faults interpretation from RS image have been analyzed, the interpretation methods of faults have been summerized, especially remote sensing automatic extraction methods and techniques have been studied. On these basis, problems and trends of faults interpretation methods from RS image are put forward.
