ABSTRACT

The objective of this paper is a geodetic measurement of the Medvedia (Bear) Cave, the largest and most beautiful cave in the National Park of Slovenský raj. The cave itself is part of the cave complex under the Glac plateau. This cave filled with beautiful stalagmites, stalactites and other cave formations was created by river erosion in tribasic limestone. The whole complex is situated in the Nature Reserve of Kysel. The entrance to the cave is situated at an altitude of 905 m asl.

The survey was realised by terrestrial laser scanner Leica ScanStation C10. Subsequently, its spatial model, individual cross-sections as well as the overall map of this publicly inaccessible cave were created. The cave is hardly accessible and unlighted. About 300 m long part of the cave with wider corridors and remains of the cave bears was the subject of the survey. The unique high-resolution 3D digital model, used mainly for the presentation of this inaccessible cave in tourism, is the main result of this geodetic measurement.
