“…The creation of apps based on the techniques of virtual and augmented reality allows users to live special experiences. Moreover, the use of virtual and AR applications allows the user to see associated multimedia contents and information directly on the subject of investigation [21][22][23][24][25]. Unlike other apps of the same type in which the main scene is generally built through the only use of images, in this case, we would directly insert a 3D model to make it explorable.…”

The tourism sector is one of the major industries in Italy that has a high impact on local communities in terms of employment and economy. To show the results of a research project highlighting the use of new technology in the tourism sector, the Geomatics Laboratory of the Mediterranea University of Reggio Calabria has developed a mobile application for tourism. The case study is "Calarcheo Park", a nonaccessible underwater archaeological park located in Reggio Calabria, near the remains of the old walls of the ancient city of Reggio Calabria (Reghion, dating back to about the VIII B.C.). The main aim of this paper is to describe the process to relive and re-propose the experience of a real immersion through a journey in virtual reality. Particular attention was given to the research part concerning the simplification processes of the models inserted within an app for tourism sector. The concept app includes scenarios (seabed) and objects (Castle and artefact) obtained from three-dimensional models realized through photogrammetric techniques, therefore "heavy" models in terms of space necessary to store them, recall them and possibly process them. Considering the visualization purpose, and the metric precision needed, the 3d models were reconstructed using a rapid method. To minimize the difficulties during the direct underwater survey carried out by a human operator (e.g. limited time available during the survey, accentuated inaccuracy due to human errors), the operations were carried out using an experimental ROV (Remote Operated Vehicles), widely used to explore underwater environments, equipped with cameras to perform photogrammetric acquisition in a single dive. To enhance the results and quality of the 3d model, a procedure to improve the image quality, and optimizing the processing is also described. This work therefore illustrates the possibilities of using 3D models created by geomatics techniques within virtual environments for apps for tourism purposes

“…They can be combined with Geographic Information System (GIS), Ground Penetrating Radar (GPR) and other traditional topography techniques to create a digital version of the heritage in its current state, being especially popular with archaeological studies. The high level of fidelity of 3D scans allows researchers to study a site or objects remotely, inspect areas that are dangerous or hard to reach (Esclapés, Tejerina, Esquembre, Bolufer, 2013), and aids in the management of complex heritage sites (Brunetaud, De Luca, Janvier-Badosa, Beck, Al-Mukhtar, 2012). Another benefit is the accumulation of a digital memory bank, which is especially meaningful for heritage sites that are deemed at risk (Kacyra, 2009).…”

“…It is possible to zoom in details and interesting areas, and authors can also add supporting visual, textual and audio resources, background characters, narrators, vegetation, animals, etc. Users have a high degree of control of how to interact with the 3D visualisation, offering an immersive and personalized exploration of virtual heritage sites as well as recreations of historical periods (Esclapés et al, 2013;Lužnik & Klein, 2015).…”

Scientific rigour of online platforms for 3D visualization of heritage

3D visualisations –including 3D scans and 3D reconstructions–designed as part of larger archaeology, history or cultural heritage projects are commonly shared with the public through online platforms that were not necessarily designed to host heritage representations and often fail to contextualize them. This paper seeks to evaluate whether five online platforms commonly used today to share 3D visualisations of heritage (Google Arts & Culture, CyArk, 3DHOP, Sketchfab and game engines) offer features that facilitate their scientific rigour and community participation, based on guidelines from International Council on Monuments and Sites(ICOMOS)and United Nations Educational, Scientific, and Cultural Organization(UNESCO). The author starts by summarizing recommendations from 32 international guidelines that are relevant to the 3D visualization of heritage, condensing them into nine key criteria: multi-disciplinary teams, objective-driven methodology and tools, careful documentation, type of reconstruction and level of certainty, authenticity, alternative hypotheses, multiple historical periods, respectful use of the heritage, and community engagement. The author proceeds to review the platforms above comparing their features with these nine recommendations and concludes that, while there are currently available features that could help to elevate the scientific rigour of the 3D visualisations and their contextualization to the public, they are not mandatory and are seldom used. The paper finishes with a recommendation for an information package to support3D visualisations of heritage on public online platforms.Highlights:<ul><li>Online platforms for the 3D visualization of heritage fail to disclose what type of reconstruction it is and its level of certainty, struggling to balance community engagement vs scientific rigour of their contents.</li><li>ICOMOS and UNESCO recommendations regarding heritage are loosely followed on the reviewed platforms, and supporting documentation is often lacking.</li><li>Scientific rigour on these platforms could be elevated with supporting textual fields to disclose further information about each visualisation.</li></ul>
