Heritage is under constant pressure to be adapted for tourism. The aim of this research was to improve the performance of both the tourism sector and the cultural heritage sector in a balanced and sustainable way, by considering the principles of conservation and preservation. Non-invasive tools such as ground penetrating radar (GPR), unmanned aerial vehicle (UAV), and even virtual reality (VR) and augmented reality (AR) technologies have been used to develop new methodologies, allowing us to generate new experiences and heritage tourist attractions, which not only do not generate negative impacts on the monuments themselves, but also promote their preservation without diminishing the cultural and tourist offers of the city. A case study was carried out on Mérida, a UNESCO World Heritage City, where tourism is a strong economic engine of the city. The results obtained are two-fold: on one hand, an effective interdisciplinary working methodology for heritage management was developed, and on the other hand, new approaches for the sustainable development of cultural tourism were generated.

“…With the limited availability of setting GCPs in inaccessible coastal cliffs, more accurate TLS-derived data that are capable of representing a part of cliffs are used as the reference instead of setting ground control points in UAS-derived data. The use of such different sensors of both TLS and UAS is often challenged in different fields of studies including 3D modeling, cultural heritage, and forestry [22][23][24], but in those cases, TLS and UAS were used as complementary to each other to cover the invisible areas from ground or air. The approach of this study is different from the previous ones in that the TLS-derived data are only used as the reference for UAS-derived data instead of GCPs.…”

Three-dimensional (3D) morphological changes in rocky coasts need to be precisely measured for protecting coastal areas and evaluating the associated sediment dynamics, although volumetric measurements of bedrock erosion in rocky coasts have been limited due to the lack of appropriate measurement methods. Here we carried out repeat surveys of the 3D measurements of a small coastal island using terrestrial laser scanning (TLS) and structure-from-motion (SfM) photogrammetry with an unmanned aerial system (UAS) for 5 years. The UAS-SfM approach measures the entire shape of the island, whereas the TLS measurement enables to obtain more accurate morphological data at a scale of centimeters on the land side. The multitemporal TLS-derived data were first aligned in timeline by the iterative closest point (ICP) method and they were used as positionally correct references. The UAS-SfM data were then aligned to each of the TLS-derived data by ICP to improve its positional accuracy. The changed areas for each period was then extracted from the aligned UAS-derived point clouds and were converted to 3D mesh polygons, enabling a differential volume estimate (DVE). The DVE for each period was revealed to be from 3.1 to 77.2 m3/month. These changes are rapid enough to force the coastal bedrock island to disappear in 30 years. The temporal variations in the DVE is roughly associated with those in the frequency of high tidal waves.

Abstract. Laser scanning or photogrammetry are useful individual techniques for digital documentation of cultural heritage sites. However, these techniques are of limited usage if cultural heritage such as the Great Wall is in harsh geographical conditions. The Great Wall is usually built on the ridge with cliffs on both sides, so it is very difficult to construct scaffolding. Therefore, the three-dimensional (3D) data obtained from the traditional 3D laser scanning is not complete. As UAV cannot enter the enemy tower, the 3D structure data inside the enemy tower with unmanned aerial vehicle (UAV) photogrammetry is missing. In order to explore effective methods to completely collect the 3D data of cultural heritage under harsh geographical environment, this study focuses on establishing a 3D model and the associated digital documentation for the No.15 enemy tower of the New Guangwu Great Wall using a combination of terrestrial laser scanning and UAV photogrammetry. This paper proposes an integrated data collection method and reduces the layout of image control points using RTK-UAV technology, which improved work efficiency and reduced work risks as well. In this paper, the internal structure data of the Great Wall enemy tower was collected by laser scanning, the external structure data was collected by UAV photogrammetry, and data fusion was based on ICP algorithm. Finally, we obtained the complete and high quality 3D digital documentation of the Great Wall enemy tower, the data can be displayed digitally and help heritage experts complete the Great Wall's restoration. This study demonstrates the potential of integrating terrestrial laser scanning and UAV photogrammetry in 3D digital documentation of cultural heritage sites.
