“…The Greek Orthodox, the Roman Catholic Franciscans, the Armenian Apostolics, the Copts, the Ethiopians and the Syrians represent the Christian Communities that are all active and each one "owns" different sections of the monument. The respectful sharing of common areas for religious ceremonies is achievable due to the Status Quo of the Holy Sepulchre, which defines the ownership, the rights and the privileges of each community (Georgopoulos et al, 2017). The most vital religious shrine that all Christian Communities are devoted to and attract thousands of pilgrims from around the world is the Tomb of Christ.…”

The significance of preservation of cultural heritage is undeniable, which is why both their geometric documentation and the creation of their digital “twins”, i.e. reconstructions and replicas at any scale, are essential procedures. A special category of cultural heritage is sacred sites which combine historical, spiritual and religious values. The most sacred monument of Christianity is the Holy Aedicule covering the Tomb of Christ in the Church of the Holy Sepulchre in Jerusalem. This paper aims to investigate and compare the various three-dimensional representations of the Holy Aedicule of the Tomb of Christ, which exist both in physical and in digital form. Initially, the main structural phases of the Aedicule are presented, including its destructions and restorations. Moreover, the different categories of the three-dimensional representations of the monument are defined. With reference to the replicas, both the reasons of their construction and their list in the form of a dataset table are presented. More specifically, in the context of this research, the three-dimensional representations of the Aedicule are divided into two major categories: the replicas constructed worldwide and the geometric documentations of the monument's condition through the years. Regarding the replicas, a list of the discovered representations is created and this database is visualized and depicted in an online web map along with essential information with the use of an open-source Geographic Information System (GIS). Based on this visualization an online web map has been created. Furthermore, the previous geometric documentations and surveys of the Holy Aedicule of the Tomb of Christ are presented. A comparison is conducted between the 3D models of the Aedicule, which were created by the University of Florence in 2007-8 and the National Technical University of Athens in 2015-17. The impact of the Holy Aedicule across the world is examined through statistics based on the type, date of construction and location of the replicas. The possible deformations of the monument's structure are detected from the assessment of the results from both the processing and the comparison of the 3D models. In conclusion, future works are suggested focusing on the discovery of the total number of replicas worldwide and the monitoring of the condition of the Aedicule. Cultural

“…The 3D textured model of the Holy Aedicule which was created during its full rehabilitation process carried out by the NTUA's Interdisciplinary team (Georgopoulos et al 2017) was used for testing and evaluation of the developed functions of this application. The above-mentioned 3D model was created combining photogrammetric and laser scanning methods therefore it is highly detailed and accurate, containing 35.414.290 triangles and being textured with high resolution (Figures 4 and 5).…”

Abstract. In the context of this paper, a virtual reality application that allows each user to perform basic topographic processes on an already created 3D model inside a virtual environment was developed. Specifically, it is an application that allows the user to perform measurements of distances between two points in three-dimensional space and measurement and extraction of the three-dimensional coordinates of any point inside the virtual reality environment. Furthermore, the created application was evaluated in terms of its functionality, its usability and metric accuracy. Before the developing stage a research was done in order to determine which virtual reality system and which game engine is most suitable to use and finally the HTC Vive® virtual reality system and the Unreal Engine 4 game engine were used. Before all that, the concept of the virtual reality science was defined and also the virtual reality technologies in today's world were analyzed.

In several cases, in the framework of cultural heritage documentation projects that prefigure the generation of dense and detailed 3D models derived from range-based or image-based techniques, the level of detail and surface characterization of the materials are strictly important, also for evaluating the conservation status of the structures. The research presented in this paper aims to evaluate the advantages and the critical issues of using a telescopic pneumatic pole to raise the position of the scans from the ground and decrease the angle of incidence of the laser beam on the surveyed object. The study also takes into consideration the use of mini UAVs and their flexibility to effectively acquire the vertical surfaces of interest even at elevated heights, comparing the density and the roughness of the derived model in comparison to the one generated by the TLS technique.
