摘要
基于异常位、高程异常差以及海面地形模型 3种方法 ,分别求出了 1985国家高程基准相对于全球大地水准面的垂直偏差 。
In this paper, the vertical shift of the origin of the 1985 national height datum with respect to the geoidal surface is calculated based on the methods of the geopotential, the difference of the height anomalies and the sea surface topography model. The results are in good consistent.
