    • n geodesy the branch of geology that studies the shape of the earth and the determination of the exact position of geographical points

Century Dictionary and Cyclopedia
    • n geodesy Formerly, the art of land-surveying in general, but now restricted to that branch of applied mathematics, distinctively called higher geodesy, which investigates the figures and areas of large portions of the earth's surface, the exact determinations of geographical positions and the azimuths of directions, the general figure of the earth, and the variations of the intensity of gravity in different regions, by means of direct observation and measurement. The operations of topography and hydrography are now considered as extraneous to geodesy, but leveling of the most precise kind is included, as well as the observation of the tides. Also geodetics.
