Computational Geodesy

Mathematical modelling of the shape of the Earth and computational methods

to measure its shape parameters is known as geodesy. In other words geodesy

models the overall shape of the Earth through mathematical modelling. The

physical properties exhibited by Earth such as its gravity field, magnetic field,

polar and Keplarian motion etc. forms the basis for modelling the shape of

Earth. In recent years direct measurement of the diameter of the Earth by

focusing the laser beams from the satellite gives a credible accuracy of the

estimations arrived by geodesic estimations. A glimpse of various applications

of geodesy and its principles ...
