基于遥感图像的海岸线提取方法研究

摘要

The coastline is the baseline of dividing the sea and the land management area. There are different foundation of the different landfore coastline regionalization, and the satellite images of the interpretion marks and extration methods are also different. According to the southeaster coast geomorphology of china, the paper study the coastling of interpretation features marks in ETM^＋ , ALOS, SAR satellite image. The different types coastline image are extracted using the digital satellite image processing technology in the test range.%海岸线是划分海洋与陆地管理区域的基准线，不同地貌的海岸线划分依据不尽相同，在卫星图像上的解译标志与提取方法也存在差异。根据我国东南沿海海岸地貌特征，研究其海岸线在ETM^＋、ALOS及SAR卫星图像中的解译特征标志，借助数字卫星图像处理技术，对试验区范围内不同类型海岸线图像进行提取。
