2. Objectives and learning outcomes
2.1 Objectives
Geodesy is closely related to the various earth sciences, especially the different disciplines of geophysics. We can determine the theoretical shape of the Earth from our knowledge of the Earth's gravity field. The rotation of the Earth, its precession and nutation, causes the temporal variation of the geodetical and astronomical coordinates. The tectonic movements of the Earth also cause the various coordinates to change continuously and significantly, leading to the development of 4D geodesy.
2.2 Learning outcomes
Upon successful completion of this subject, the student:
A. Knowledge
- Is familiar with the terminology of earth sciences
- Understands the relationship and interdependence of geodesy and earth sciences
- Knows the concept and the geodetic significance of the field forces of the Earth, the inner structure and the rotation of the Earth
- Understands the relationship between the shape and the gravity field of the Earth
- Understands the reason of physical background of larger geoid anomalies and the time variation of geoid anomalies
- Is aware of the physical basis of Earth's rotation, knows exactly the phenomenon of precession and nutation
- Understands the relationship between the rotation and the equilibrium shape of the earth
- Understands the changes in terrestrial and astronomical coordinates due to precession and nutation
- Understands the significance of oceanography and meteorology in geodesy
- Knows the global tectonics of the Earth
- Understand the revolutionary importance of 4D geodesy
B. Skills
- Is able to understand the relationship between geodesy and different earth sciences
- Is able to understand the different geodetic subjects on the basis of his basic knowledge of earth sciences
C. Attitudes
- Cooperates with the lecturer and fellow students in expanding the knowledge
- Considers importance attending lectures and continuous mid-year learning
- In addition to the compulsory curriculum, it expands its knowledge through continuous acquisition of knowledge
D. Autonomy and Responsibility
- Carry out his studies with appropriate responsibility
- Openly accepts well-founded critical remarks
- Assists fellow students in preparation in necessary situations
