| 摘 要： | 为实现海岸带测量成果陆部要素与海部要素在垂直方向的基准统一,首先建立了一般陆海部要素包括灯塔、灯标等特殊海部要素在垂直方向的基准转换关系;其次构建了高精度的理论最低潮面、海面地形(验潮站平均海面高程)等潮汐数值模型;最后对海岸带垂直基准转换作了精度估算。 研究表明,一般海部要素的垂直基准转换精度优于 35cm,灯塔、灯标等特殊海部要素的垂直基准转换精度优于 45cm。

| Abstract: | In order to achieve the universal vertical datum between the land feature and the ocean feature in coastal zone, some key technique were researched: First, the transformation model of the vertical datum, specially including the beacon and the marine lights, is built; Second, the tide model and the sea surface topography model are established; Third, precision about the transformation model of the vertical datum is estimated. The research indicate: the transformation precision of some common ocean feature is excelled than 35 cm,the transformation precision of some special ocean feature,for example the beacon and the marine lights,is better than 45cm. |
