摘　　要：常用于水边线提取的遥感手段主要有卫星光学遥感、微波遥感和激光雷达技术。从这三种常用的水边线提取遥感技术角度出发,分析比较了基于各类型数据提取水边线的主要方法原理、特点及适用情况。介绍了潮位校正和基于DEM数据的两种获取真实海岸线的研究方法及三维激光扫描数据的应用。最后就目前该领域的不足之处提出了今后研究的可行性建议。As remote sensing technology has prominent advantages of being macroscopic, full-time, fast, high- frequency and low cost ,it is very suitable to acquire coastline.Remote sensing methods used in waterline extraction mainly include optical remote sensing, microwave remote sensing and laser radar technology. The principles, characteristics and applicable conditions of waterline extraction main method were analyzed and compared based on these three kinds of common remote sensing technology of waterline extraction.Then this paper introduces the two kinds of methods with tide correction or DEM data to obtain real coastlines and the application of 3d laser scan data.At last ,feasible suggestion of the future research is forecasted based on its existent insufficiency.
