摘要:At present, all kinds of vertical datum can only suit partial sea so that it leads to severe questions in three fields: data conjoint, data switch and export, data application. This paper puts forward the establishment idea, confirms the technique route of the building, and analyses the key problems. Then the establishment solutions are given: firstly, the suitable vertical datum should be chosen based on the tidal character of local sea separately; secondly, the conversion model among the different vertical datum should be established; thirdly, the transition model in neighborhood should be set up. Then the marine vertical datum seamless system is built, which can reflect the interrelation among the different vertical datum and suit the whole sea.
