- noun The geologic science of the size and shape of the earth.
from The Century Dictionary.
- noun 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.

- noun (Math.) That branch of applied mathematics which determines, by means of observations and measurements, the figures and areas of large portions of the earth's surface, or the general figure and dimenshions of the earth; or that branch of surveying in which the curvature of the earth is taken into account, as in the surveys of States, or of long lines of coast.

Just curious, is there a particular subset of quasars that are typically used in geodesy?
Time is important in geodesy and we use all kinds of clocks.
I suppose few of you know what geodesy is let alone understand how Vanguard 1 or any other space technology improved this particular branch of geoscience.
The technology has transformed geodesy, but for it to work, a GPS-enabled device must be present at the site of whatever is being measured—on the bank of a river, say, or at the top of Everest.
Datum remains standard and retains the general meaning of “a unit of information”, though it tends to appear mostly in academic and specialist disciplines such as philosophy, surveying, geodesy, topography, technical drawing, and cartography:
Naming it after the Persian polymath who is considered by some the father of geodesy and geology and who calculated the radius of Earth to about 17 km of its actual value 500 years before anyone in Europe figured it out would go a long way to acknowledge that people in the Middle East also have made great contributions to the knowledge of mankind just as Galileo and Cassini have. former CA resident
One approach, which is expensive and not yet widely applied, is called seafloor geodesy.
As much as climbing the Himalayan peak is a signature accomplishment for mountaineers, so measuring it accurately is a signature goal for scientists in the field of geodesy, or the measurement of Earth.
It also emphasizes the need to do seafloor geodesy.
We could produce weather visualizations for any country or the whole world, taking advantage of the new integrated geodesy system to visualize in Mercator or any other cartographic projection.
