摘要
探讨了我国海洋测绘垂直基准存在的问题,并总结了目前国内外相关研究的主要成果。同时,提出解决该问题的两种技术路线,需要深入研究的内容:建立偏差模型、构建高精度潮汐模型和精化海域大地水准面。
The present problems related to the vertical datum in China＇s marine geodesy are discussed.The main domestic and abroad achievements in the relevant studies are summarized.The two kinds of technological approaches for solving the problems,and the contents which need thoroughly studying are put forward,including developing a separation model,establishing high precision tidal model and refining the marine geoid.
