### New Detailed Map and Sections of the Cave  
Given the fact that the scanning at individual survey stations is realized in the local coordinate system of the scanner, we also determined the orientation towards another known survey point in order to make direct georeferencing based on the known coordinates of the 6\" HDS targets. After the scanning at all survey stations in the cave, the registration of individual point clouds into the common coordinate system was performed in the Leica Cyclone software. As a result, a database of points that allows the visual inspection of individual shapes of the Ochtina Aragonite Cave was obtained (Figure 6). Resulting from the new survey of the cave by TLS, the area of its ground plan is 1335 m\({}^{2}\). In terms of gross morphology and ground plan pattern, the cave is composed of parallel tectonically controlled passages and halls that are interconnected through smaller transverse conduits of phreatic and epiphynreatic morphology with numerous ceiling cupolas and smaller spherical cavities, flat ceiling, inward inclined smooth facets, as well as spongework-like hollows. The whole cave represents a labyrinth with a high degree of connectivity. Vertical cross-sections of individual parts of the cave were created from the point cloud by its subsequent processing in CAD systems--Microstation V8i and Leica Cloudworks (Figure 7). The places of cross-sections (\"A\"-\"I\") were selected to view different morphological features significant for the reconstruction of cave origin and development (Figure 6). Figure 6: Top view of the final point cloud with a position of cross-sections through the point cloud and site of the survey realized by digital close-range photogrammetry (DCRP). The longitudinal sections A and B show that the Ochtina Aragonite Cave is a subhorizontal cave, in several places including enlarged ceiling fissures and cupolas, as well as looped conduits below the floor level. Mostly horizontal passages and halls are located in the central part of the cave. They lead east and west into the peripheral tectonically controlled halls. The peripheral halls are featured by lower-lying floors. Measurement data testify the same altitude of the water table of lakes in the Deep Chamber and in the small cavity at the western edge of Entrance Hall (the water table of these lakes

The uppermost place of the cave (A, B; the northern part of the cave) relates to the highest part of the fissure passage leading through the Entrance Hall to the Marble Hall. This passage is controlled by a steep NE-SW fault that predisposed the origin of the western part of the cave (Figure 6 and Figure 12). The lowest places occur at the floor of the Entrance Hall and at the bottom of the Deep Chamber at the lake (B; the western edge of the cave or the NE edge of this chamber). The vertical span of the \"dry\" part of the cave is 30 m (Figure 7; cross-section \"B\"). Since divers have reached a depth of 3 m below the water table of this lake [37], the total vertical span of the Ochtna Aragonite Cave is 33 m.  
Flat solution ceilings and wall inward-inclined smooth solution facets, typical medium-scale morphological features of the Ochtnia Aragonite Cave [12; 13; 14; 38], are documented by the cross-sections G and H. Facets as solution inward-inclined smooth wall surfaces generally maintain a slope of approximately 40-45 degrees, independent of an inclination of bedding planes or lamination [16]. In Ochtnia Aragonite Cave, they were detected in several morphological constellations [14; 38]. In the transverse passages, facets are mostly associated with a flat ceiling (triangular cross-section--Laughohle profile after Biese [39]).
