This paper first discusses the background of the topic, including the difficulties of the problem and the evaluation methods. Then Ave typical method currently proposed for road extraction are reviewed. Technical details are critically reviewed for future reference and comparison. The advantages and disadvantages of each approach are discussed. Based on this discussion, future work and possible methods are suggested.
