Morphological analysis of 3D subsurface structures with the use of a handheld laser scanning system. The case study of Koutouki Cave, Peania, Greece.

In the presented case study, we combined remote sensing techniques and lidar technology by using a handheld laser scanner in order to generate a complete 3D model of the Koutouki Cave, at Peania, Greece (Fig.1). Using open – source software we made a quantification analysis of the terrain and generate morphological features of the speleothems with high accuracy and detail in order to estimate the speleogenesis and monitor the evolution of the cave (Fig. 2).

Fig. 1: Different aspects of the point cloud looking north (a) and south (b). The color scale represents the elevation variation, whilst parts of the cave have been removed in order to reveal the speleothems and human intervention (stairs, passage, platform).


Fig. 2: (a) Column classification according to their base elevation. The highest base elevation altitudes are located at the westernmost and the lowest at the easternmost parts of the cave. The highest percentage of columns was based at the mean elevation of the cave (516.5 m) (b) Column classification according to the column height. The highest are located also on the west side of the cave at 7.23 m (column no. 1) and 5.8 m (columns no. 5) height.
