摘要
介绍了椭球面、大地水准面、平均海面和海图深度基准面的定义。系统分析了潮汐基准面和大地水准面不适合作为无缝垂直基准面的原因,及以椭球面作为无缝垂直基准面的合理性和可行性,并建议选择WGS84椭球面作为我国海域的无缝垂直基准面。
The definitions of ellipsoid,geoid,mean sea level,and chart datum are introduced.The reasons for the tidal datum and the geoid being unsuitable as the seamless vertical datum are analyzed systematically.Also the rationality and feasibility for using ellipsoid as seamless vertical datum are analyzed.It is recommended to choose the WGS84 ellipsoid as the seamless vertical datum of Chinese sea area.
