“…This technology has revolutionized cave mapping in the last decade (Canevese et al, 2009;Rüther et al, 2009;Buchroithner et al, 2011;Zlot and Bosse, 2014;Gallay et al, 2015a;Idrees and Pradhan, 2016). The scanner emits laser beams and records the reflected electromagnetic energy with a high frequency and accuracy.…”

Abstract. The change of hydrological conditions during the evolution of caves in carbonate rocks often results in a complex subterranean geomorphology, which comprises specific landforms such as ceiling channels, anastomosing half tubes, or speleothems organized vertically in different levels. Studying such complex environments traditionally requires tedious mapping; however, this is being replaced with terrestrial laser scanning technology. Laser scanning overcomes the problem of reaching high ceilings, providing new options to map underground landscapes with unprecedented level of detail and accuracy. The acquired point cloud can be handled conveniently with dedicated software, but applying traditional geomorphometry to analyse the cave surface is limited. This is because geomorphometry has been focused on parameterization and analysis of surficial terrain. The theoretical and methodological concept has been based on twodimensional (2-D) scalar fields, which are sufficient for most cases of the surficial terrain. The terrain surface is modelled with a bivariate function of altitude (elevation) and represented by a raster digital elevation model. However, the cave is a 3-D entity; therefore, a different approach is required for geomorphometric analysis. In this paper, we demonstrate the benefits of high-resolution cave mapping and 3-D modelling to better understand the palaeohydrography of the Domica cave in Slovakia. This methodological approach adopted traditional geomorphometric methods in a unique manner and also new methods used in 3-D computer graphics, which can be applied to study other 3-D geomorphological forms.

“…Terrestrial laser scanning measures the threedimensional spatial information of an object within a certain distance from the ground using a laser (Rüther et al, 2009;Fabbri et al, 2017). This method can quickly acquire the geometry of a large cultural heritage site because of its high operation speed, mobility, and accessibility.…”

ABSTRACT:Three-dimensional digital documentation is an important technique for the maintenance and monitoring of cultural heritage sites. This study focuses on the three-dimensional digital documentation of the Magoksa Temple, Republic of Korea, using a combination of terrestrial laser scanning and unmanned aerial vehicle (UAV) photogrammetry. Terrestrial laser scanning mostly acquired the vertical geometry of the buildings. In addition, the digital orthoimage produced by UAV photogrammetry had higher horizontal data acquisition rate than that produced by terrestrial laser scanning. Thus, the scanning and UAV photogrammetry were merged by matching 20 corresponding points and an absolute coordinate system was established using seven ground control points. The final, complete threedimensional shape had perfect horizontal and vertical geometries. This study demonstrates the potential of integrating terrestrial laser scanning and UAV photogrammetry for three-dimensional digital documentation. This new technique is expected to contribute to the three-dimensional digital documentation and spatial analysis of cultural heritage sites.

“…Anfiteatro Flavio 1994-1998 as well as the analysis of architectural façades and the analysis of sculptural complexes (Levoy et al, 2000). Since then, several archaeological sites from around the world have made use of these technologies for different purposes, resulting in a profuse quantity of literature documenting the results of these experiments (Balzani et al, 2004;Lambers et al, 2007;Frischer & Dakouri-Hild, 2008;Reindel & Wagner, 2009;Guidi et al, 2009;Rüther et al, 2009;Benedetti et al, 2010;Stanco et al, 2011;Guidi et al, 2013Guidi et al, , 2014.…”

During the last few decades, 3D scanning devices and 3D digital image generating technology has been developed to the point where they significantly reduce errors and time during data collection thus making them highly appropriate tools in the field of archaeology. With regards to surveying, terrestrial laser scanning and digital photogrammetry, they are a viable alternative to traditional methods for measuring. Nevertheless, these technologies are rarely used in projects in the Maya region, even though they offer a wide range of applications, which could be explored and utilised in this subtropical environment. This paper presents the results of digital surveying involving two Maya archaeological sites in Guatemala: La Blanca and Chilonché, as well as demonstrating their effective application for “investigating into the past”.
