- International Fees
International fees are typically 3.12 times the domestic tuition. Exact cost will be calculated upon completion of registration.
Course Overview
This course covers geodesy topics such as the earth's gravity field, gravity potential, equipotential surfaces, normal gravity field, gravity anomaly, disturbing potential, geoid models and their computations using terrestrial and satellite measurements, and their realizations. The course also discusses height systems, vertical datums, and datum transformations, with an emphasis on North American vertical datums. Students learn the topic of physical geodesy through a series of lectures and assignments.

Learning Outcomes
Upon successful completion of this course, the student will be able to:
- Distinguish the effects of gravity on survey instruments and field procedures.
- Discuss the earth's gravity field and gravity potential.
- Recognize how surface gravity is measured in absolute and relative sense.
- Explain the earth's normal gravity model, gravity anomaly and its variations.
- Apply corrections to gravity measurements.
- Describe disturbing potential and Brun's formula.
- Explain the fundamental equations of gravity potential.
- Express gravity potential as a function of spherical harmonics and interpret the coefficients.
- Discuss tide gauge/leveling and gravimetric methods of geoid determination.
- Identify mean sea level (MSL), sea surface topography (SST), and geoid.
- Explain the fundamentals of satellite gravimetry and satellite altimetry methods.
- Describe recent satellite missions used for geoid determination.
- Explain astro-geodetic geoid determination.
- Discuss and discriminate between various vertical datums and geoid models used in North America.
- Distinguish different height systems.
