Abstract-The West Digital Conservatory of ArchaeologicalHeritage p r o j e c t , a . k . a . W D C A H , i s a n e w F r e n c h r e s e a r c h organization whose aim is to both ensure the preservation of digital archaeological data, and deliver expertise in production, analysis, visualization and virtual reality exploration techniques. This project is an interdisciplinary project composed of engineers and researchers in archaeology, computer science, virtual reality and 3D interaction with virtual environments. The major objectives of this conservatory project are: (i) sustainable and centralized safeguarding and archiving of 2D/3D data produced by the archaeological community; (ii) free access to metadata; (iii) secure access to data for the different actors involved in scientific projects and (iv) the support and advice for these actors in the 3D data production and exploration through the latest digital technologies, modeling tools and virtual reality systems. This paper focuses on the first activities of the WDCAH which mainly concern digital models production using photogrammetry, 3D laser scans, and 3D computer graphics software. We are currently working on the reconstitution of six archaeological sites located in the west of France ranging from prehistory to the Middle Ages: the Cairn of Carn Island, the covered pathway of Roh Coh Coet, the Goh Min Ru megalithic site, the gallo-roman mansion of Vanesia, the keep of the Château de Sainte-Suzanne, the Porte des Champs of the Château d'Angers. Other proposals are currently under study.Index Terms-Archaeological heritage -digital preservationVirtual archaeology-3D models.
In the continuation of the 3D data production work made by the WDCAH, the use of virtual reality tools allows archaeologists to carry out analysis and understanding research about their sites. In this paper, we focus on the virtual reality services proposed to archaeologists in the WDCAH, through the example of two archaeological sites, the Temple de Mars in Corseul and the Cairn of Carn Island.
Mass graves are usually key historical markers with strong incentive for archeological investigations. The identification of individuals buried in mass graves has long benefitted from traditional historical, archaeological, anthropological and paleopathological techniques. The addition of novel methods including genetic, genomic and isotopic geochemistry have renewed interest in solving unidentified mass graves. In this study, we demonstrate that the combined use of these techniques allows the identification of the individuals found in two Breton historical mass graves, where one method alone would not have revealed the importance of this discovery. The skeletons likely belong to soldiers from the two enemy armies who fought during a major event of Breton history: the siege of Rennes in 1491, which ended by the wedding of the Duchess of Brittany with the King of France and signaled the end of the independence of the region. Our study highlights the value of interdisciplinary approaches with a particular emphasis on increasingly accurate isotopic markers. The development of the sulfur isoscape and testing of the triple isotope geographic assignment are detailed in a companion paper [13].
This work illustrates the use of three different digitization techniques in order to study and valorize a 15th century engraved tablet discovered during a preventive archaeological excavation in the area of a former convent. The tablet is covered with engraved inscriptions on both sides, and includes a musical score. Digitization allowed for an advanced analysis of the inscriptions, and to generate a complete and precise 3D model of the artifact which was used to produce an interactive application deployed both on tactile tablets and website. The interactive application integrates a musical interpretation of the score that gives access to a testimony of intangible heritage. This interdisciplinary work gathered archaeologists, researchers from computer science and physics, and a professional musician. CCS Concepts: • Applied computing → Arts and humanities; • Computing methodologies → Computer graphics.
