All geodetic surveys are conducted in the Earth's gravity field, hence gravity surveys play a crucial role in geodesy. For example, without gravimetry we would be unable to determine the form of the geoid and the Earth’s dimensions. The aim of the Master’s thesis was to determine whether it was possible to discover a cave with the help of gravity surveys. We conducted the surveys in the territory of Županova jama Cave in the vicinity of Grosuplje. The thesis consists of the theoretical and practical part. The theoretical part introduces the concepts of gravity field, gravity force, gravitational acceleration, and the Real Time Kinematic (RTK) survey method. This part also includes a description of the used instruments. The practical part includes a description of the process of obtaining terrain surveys (the RTK method and relative gravity surveys). In the second part of the thesis, we present the processing of the surveys. We calculated the drift, the relative and absolute gravitational acceleration, corrections, and anomalies for the measured points. Based on the free-air anomaly and the Bouguer anomaly we produced two anomaly maps – one for the immediate surroundings of the Županova jama Cave and one for its wider area. Based on the graphic representation of the anomalies, we concluded that Županova jama Cave can be identified with the help of gravity surveys.
