DEFINITION AND FUNDAMENTAL GOALS OF GEODESY:

Geodesy deals with the measurement and representation of the earth, including its gravity field, in a three-dimensional time varying space.

The major geodetic goals may be summarized as follows:
a) Establishment and maintenance of local, regional, national, continental and global three-dimensional geodetic control networks.
b) Measurement and representation of geodynamic phenomena (polar motion, spinning, earth tides, plate motion, local crustal movements, etc.)
c) Determination of actual gravity field of the earth including temporal variations.

The objectives of the courses offered are then to provide the student with the necessary knowledge and skills for such geodetic activities as
1) Treatment of the existing national geodetic control networks,
2) Geodetic applications in global, regional and local geodynamics programs (especially in earthquake studies), and
3) Detection and monitoring of deformations of very large structures.
