Zusätzliche Informationen zu Terminen:
Lecture in Summer Semester 2021:
• 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!!
• Once a week we will have a live meeting on Zoom. 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 HCU Chat or email.
• The exercises will be uploaded together with the lecture to be solved by each person individually. Questions can be asked in the chat. Solutions for the exercises will be provided for self-checking.
• There will be one larger voluntary homework assignment.
Beschreibung:
Physical Geodesy
Gravity and gravity potential, pseudo forces, tidal forces, parameters of the normal gravity field, computation of normal gravity. Disturbing quantities in the earths gravity field: gravity disturbance, gravity anomaly, deflection of the vertical. Earth models, spherical harmonics. Height systems (dynamic, orthometric, normal), vertical datum.
Mathematical Geodesy
Elements of spherical trigonometry: sphere, small circles, great circles, 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 curves. Azimuth and angle corrections, distance corrections. Geodetic mapping of the ellipsoid surface onto a plane: general relationships, fundamental form of surface theory, mappings of major importance (Mercator, Gauss-Krüger or Transverse Mercator, UTM); mapping equations, magnification or point scale factor, meridian convergence.
