Students knows the rules of astronomic leveling and base of the solution of Bjerhammar problem. Student knows theoretical basis of gravity measurements. Skills: Student can monitor, interpret and model the processes associated with kinematics and dynamics of the Earth. Student can choose the method of measurement used to assess changes in surface and subsurface Earth's crust. Student is able to assess the effects of tectonic and postglacial processes and their relationship to changes in height and gravity. Student can explain the reasons for the movements of tectonic plates and the pole. Student is able to determine the value of the different characteristics of the Earth gravity field based on global geopotential models. Student is able to determine the value of the basic gravity corrections and reductions. Student is able to determine the corrections to precise leveling due to the height systems and tidal changes of the gravity field. Student is able to determine height of the geoid and deflection of the vertical based on gravity data. Student is able to determine gravity differences and vertical gradient of the gravity. Social competence (attitudes): Student is aware of the need to improve knowledge of the geophysical processes that cause the evolution of the interior and the surface of Earth, and their impact on geodetic and geophysical measurements. Student demonstrates understanding of the impact and the importance of continuous training and improving professional competence. Student is aware of and understands the validity of the non-technical aspects of the surveyor.
