geodetic datum
See Also: datum, horizontal geodetic datum, vertical geodetic datum
[geodesy] A datum that is the basis for calculating positions on the earth's surface or heights above or below the earth's surface.
Geodetic Surveys - are surveys, which take into account the true shape of the earth.
The World Geodetic System is a standard for use in cartography, geodesy, and navigation.
The astrogeodetic data in its basic form consists of deflection of the vertical components referred to the various national geodetic datums. These deflection values were integrated into astrogeodetic geoid charts referred to these national datums.
