摘　　要：对Google Earth免费提供的高分辨率的卫星影像有效地用到海岸线修测调查中做了探讨。Google Earth提供的卫星图像匹配了视图的经纬度等位置信息,并可以放入点、线和面等标记,基于其高清遥感地图的岸线位置与走向能直接反映海岸线最新变化情况。通过对上海市海岸线修测数据在GE平台上进行验证,双向分析修测点位精度和GE精度,提出数据判读、岸线自动提取等功能应用。The technique tips of coastline survey and coastline retrieved by the Google Earth remote-sensing image are analyzed in this paper. The Google Earth provides the free satellite remote sensing images, matches the view orientation and altitude, lat and Ion, and the point labels, paths, polygons, and images can be embedded in it. Based on the high-clear three-dimensional image and collected or gained information, the latest position of coastline and the trend of it＇s movement can be portrayed. Finally, the coastline survey data in Shanghai as an example, through bidirectional analyzing of precision of the data, GE application in data judgment and automatic coastline pickup can be done.
