There are two methods to survey the natural cave. One is plane table surveying and the other is recording chart surveying. The drawing maps drawn by these methods are 2D. Furthermore, it is difficult to figure out the accurate dimension about full sections and whole interior products because of use of plane table and recording chart. Accordingly, in this study, the 3D spatial information about Dangcheomuldonggul was constructed by the Terrestrial LiDAR and high resolution digital camera where is belong to Jeju Volcanic Island and Lava Tubes as the first World Natural Heritage of the Republic of Korea. Also, the utilization possibility of 3D spatial information was suggested to the basic data of deformation and change detection through structure analysis, section analysis, shape analysis, and interior products analysis.
