Prerequisite Form of prerequisites
Mathematics for geodesy and Geodetic astronomy. Completed classes for attending classes, and none for final exam.
Learning objectives
Introducing students to the theoretical and practical aspects of physical geodesy, the problems of boundary values of the theory of Earth's gravitational potential and mathematical models used in determining the reference geodetic surfaces.
Learning outcomes
The student should be able to: 1) describe and explain the influence of the Earth's gravitational field and its importance in modeling reference geodetic surfaces, 2) define and use different height systems, 3) model and apply datum transformation parameters, 4) model the gravitational influence of topographic masses of the Earth's crust, 5) understand the basics of Molodensky's theory, 6) creates and applies the collocation model in predicting / estimating the functionals of the anomalous potential of the Earth's gravitational field, etc.
