海岸是界定省、区、市海域行政边界的重要依据，关系到权力下放。海岸线可以从遥感数据中提取。然而，对于海岸和低水位处的垂直基准面的定义却完全不同。水文制图中所用的海岸线的海水位为平均高海平面（MHSL），大地制图中所用的海岸线的海水位为平均海平面（MSL）。然而，遥感数据记录在特定的时间，也有特定的海水水位，可能是在高或低的海平面取决于位置。这项研究的目的是了解海平面的位置，
获取Landsat 7时的海岸线测绘以及如何调整以定义标准的海岸线。在椭球体、基准面和投影系统相同的条件下，对543（RGB）1：50.000比例尺海图和导航图的陆地卫星ETM+合成图进行了叠加比较。在海岸过程动态变化不明显的区域，影像与地图的叠加结果表明，海岸线相互匹配。但在有指示性变化的区域，影像上的海岸线与地图上的海岸线存在一定差异。获取图像时的海平面位置处于高海平面，图像海岸线与水文海岸线一致
线当在不同水位位置上获取图像时，存在两个条件。海岸线的位置在无0米等高线的区域不会发生变化，在有0米等高线的区域会发生变化。应在第二种情况下进行调整。关键词：海岸线，陆地卫星
Shore line is important to define seawater administration borders of a province, a district, and a city related to decentralization. The shore line can be extracted from remote sensing data. However, the definition of vertical datum reference for the shore line and low water level place are totally defferent. The sea water level position for shore line used in the hydrographic mapping is mean high sea level (MHSL), while the sea water level for shore line used in the geodetic mapping is mean sea level (MSL). However, remote sensing data were recorded in specific time that also have a specific sea water level, might be in a high or a low sea level depending on the location. Objectives of this research are to understand the position of the sea water level for the
shore line mapping when the Landsat 7 is acquired and how to adjust to make a standard shore line definition. The landsat ETM+ compositing of 543 (RGB) Maritime and Navigation Map of 1 : 50.000 scale were overlaid and compared in same condition of spheroid, datum, and projection system. In the area where there is no significant change due to the dynamic of coastal processes, the result of the overlaid image and map indicated that the shore line matched between each other. However, in the area where there are some indicated change, resulted on some differences between the shore line from the image and the map. The sea level position when the image was acquired was in high sea level and the image shore line was as same as the hydrographic shore
line. There are two conditions when an image is acquired on a difference water level position. The shore line position would not change in area without 0 meter contour line and would change in area have 0 meter contour line. Adjustment should be made in the second condition.
