Definition of Geodesy
Geodesy or geodetics, is the scientific
discipline that deals with the
measurement and representation of the Earth, including its gravitational field in a
three-dimensional time-varying space. It is the branch of surveying which takes into
account the size and shape of the Earth. Geodesists determine the size and shape of the
Earth as well as the exact position of points on the surface. These tasks require
astronomical
observation for time, latitude, longitude and azimuth. Triangulation
includes the measurement of the force of gravity, terrestrial magnetism; leveling and
sounding of oceans, lakes, and rivers; study of tides and currents. To determine the
most probable values of the observed quantities, the method of least squares is used.
Geodesists also study geodynamical
phenomena such as crust motion, tides,
and polar motion. For this they design global and national control networks, using
space and terrestrial techniques while relying on datum and coordinate systems.
Geodesy (from Greek "division of the Earth")
is primarily concerned with positioning
within the temporally varying gravity field. It should be said that in the German
speaking world geodesy is divided into "Higher Geodesy", which is concerned with
measuring
the Earth on the global scale, and "Practical Geodesy" or "Engineering
Geodesy", which is concerned with measuring specific parts or regions of the Earth,
and which includes surveying.
