Systematic Error of the 1985 National Height Datum

  • 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.
