Course abstract

Students gain knowledge about the type and size of the Earth, coordinate systems used in geodesy, about the types of geodetic measurements, mathematical processing of measurements and accuracy of measurements, about the representation of the earth's surface in plans and maps. Learns the measurement of angles and magnetic azimuths. Students gain knowledge about distance measurement and leveling. Students gain an understanding of how GNSS works, aerial photography, laser scanning and GIS.
