# GMGD200 Geodesy

Credits (ECTS):10

Course responsible:Jon Glenn Omholt Gjevestad

Campus / Online:Taught campus Ås

Teaching language:Norsk

Course frequency:Annually

Teaching and exam period:This course has teaching/evaluation in Autumn parallel.

In February 2015 the UN General Assembly adopted the resolution "A Global Geodetic Reference Frame for Sustainable Development" - the first resolution recognising the importance of a globally-coordinated approach to geodesy. Geodesy plays an increasing role in people’s lives, from finding directions using a smart phone to alleviating poverty.

Because the Earth is in constant motion, an accurate point of reference is needed for making measurements. Geodesy provides a very accurate and stable coordinate reference frame for the whole planet: A Global Geodetic Reference Frame.

Ref: United Nations Global Geodetic Reference Frame (UNGGRF)

The course gives an introduction to: basic geodetic calculations, map projections, height systems and physical geodesy. The course deals with subjects such as: coordinate systems, spherical geometry, ellipsoidal geometry, geodetic direct- and indirect problems, linear transformations, geometrical corrections and height systems.

### Learning outcome

Students are given an introduction to geometrical and physical geodesy.
• Lectures and independent assignments.
• Teaching support will be given primarily in connection with that part of the structured teaching that is set aside for exercise guidance. It will also be possible to communicate directly with the course teacher by appointment during office hours.
• GMLM102, INF120
• 3 hour final written examination. Grading A-F.

One written exam Grading: Letter grades Permitted aids: C1 All types of calculators, other aids as specified
• The external and internal examiner jointly prepare the exam questions and the correction manual. The external examiner reviews the internal examiner's examination results by correcting a random sample of candidates exams as a calibration according to the Department's guidelines for examination markings.
• Exercises. Compulsory, submitted work must be passed in order for the candidate to gain access to the exam.
• Lectures: 52 hours. Exercises: 26 hours.
• Special requirements in Science
