Zusätzliche Informationen zu Terminen:
Lecture in Summer Semester 2020:
• The lecture will consist of lectures and some accompanying exercises.
• The lecture will be provided one week before the indicated date in the following two ways
o Powerpoint slides as PDF
o Redcorded lectures (videos of the slides with oral explanations)
The slides and/or videos should be studied before the actual date indicated in the schedule!!
• At the time indicated in the schedule (Thursday, 8:30), we will have a live meeting via video conference. Here we will give a short summary of the lecture material and there will be the chance to ask questions.
• Additional options for asking questions will be offered via the Moodle forum, email or live chat.
• The exercises will be uploaded after the lecture to be solved by each person individually. Solutions for the exercises will be provided for self-checking.
• There will be one larger homework assignment, which is required to pass in order to take part in the exam.
• Help for the homework assignment will be provided individually via chat/email/video conference tool.
Beschreibung:
Mathematical Geodesy
Elements of spherical trigonometry: sphere, small circles, great circles, spherical two-angle, spherical triangle, funda-mental laws in the spherical triangle, Delambre’s and Napier’s equations, first and second Napier’s rules, differential equations, application examples. Reference ellipsoid: ellipsoid parameters, latitudes, curvature radii. Three-dimensional geodesy: 3D ellipsoidal coordinates, 3D geocentric Cartesian coordinates, coordinates in the local geodetic and astronomical system, coordinate transformations, observation equations in three-dimensional geodesy, differences between natural and ellipsoidal coordinates. Geodesic curve on the rotational ellipsoid: normal section and geodesic curve, mathematical description of the geodesic. Azimuth and angle corrections, distance corrections. Direct and inverse geodetic problems: computations of length and azimuth of a geodesic, computation of ellipsoidal coordinates. Geodetic mapping of the ellipsoid surface onto a plane: general relationships, mappings of major importance (Mercator, Gauss-Krüger or Transverse Mercator, UTM); mapping equations, magnification or point scale factor, meridian convergence, direction and distance correction; other mappings. Geodetic reference systems: comparison of different datums, transformation equations and transformation parameters.
Physical Geodesy
Gravity and gravity potential, parameters of the normal gravity field, computation of normal gravity.
Height systems (dynamic, orthometric, normal), vertical datum. Disturbing quantities in the earth’s gravity field: gravity disturbance, gravity anomaly, deflection of the vertical. Geoid determination: astrogeodetic method, gravimetric method, combined methods. Earth models, high resolution gravity field representation.
