Purpose of the course: This course is aimed at the modeling of earth and definition of geocentric coordinate systems in which the coordinates of the objects on and near the earth's surface are expressed. Grasp the methods of precise determination of relations between coordinate systems, and to acquire certain skills by making numerical calculations. It is aimed to establish relationships between the measurements on the earth and the elipsoid, thus gaining the geometric reductions and the calculation skills related to the measurements.In this context, the student will develop their skills for the expected accuracy of the method that should be used in the related project
