The basic principles of geodesy are presented in an elementary form. The formation of geodetic datums is introduced and the necessity of connecting or joining datums is discussed. Methods used to connect independent geodetic systems to a single world reference system are discussed, including the role of gravity data. The 1983 edition of this publication contains an expanded discussion of satellite and related technological applications to geodesy and updated description of the World Geodetic System. The basic principles are presented through discussions of various geodetic topics such as ellipsoids, geoid, horizontal surveying, leveling, geodetic datums and gravity.
