| 摘 要： | 从目前数字海洋地图的现状出发，针对数字海洋地图由分幅存储方式带来的叠幅（图幅间存在重叠区域）和缝隙两个问题，提出了一种无缝拼接的算法。算法可去除图幅之间的重叠区域，并且可以有效去除由分幅导致的缝隙，将多个图幅的图层要素拼接为物理无缝的数据。

| Abstract: | According to the current situation of digital chart, an alogrithm of seamless contiguity has been proposed to address the overlap and gap due to chart subdivision. This alogrithm could wipe out the over- lapping areas of the adjoining sheets, and furthermore remove the gap between the adjoining sheets. With the merging results as physically seamless datas from map features of multi-sheets. |
