New pieces in the picture puzzle of an astrogeodetic geoid map of the world
Abstract The astrogeodetic geoid map presented to the IUGG at Helsinki in 1960 has been updated to reflect the accumulation of new data. The geoid map of North America has been recomputed, that of South and Central America enlarged. A geoid chart of Australia has been added. Various other improvements were made Terrestrial gravity was used for interpolation, and satellite observations for intercontinental connection. World datum parameters were derived in various solutions. Satellite positioning of the major astrogeodetic datum blocks leads to an equatorial radiusa=6378142 m for a flatteningf=1/298.25. If surface gravity is included, the radius is larger. A reference figurea=6378150 m andf=1/298.3 is recommended for practical applications?
