This paper describes and validates a method for using multispectral imagery captured by unmanned aerial vehicles (UAVs), subsurface geophysical surveys, and stratigraphic excavations to evaluate the role of 3D semantic visualizations for the collected data. The information recorded by various methods will be experimentally reconciled using the Extended Matrix and other original open-source tools, keeping both the scientific processes that generated them and the derived data separate, transparent, and reproducible. This structured information makes immediately accessible the required variety of sources useful for interpretation and reconstructive hypotheses.

We focus on a bottom-up approach starting from a series of datasets ranging from the 3D digitalisation of monuments and sites to the creation of reconstructive records (including the scientific documentation they are based on), to the implementation of digital storytelling and to the development of open source-based web-apps. We propose the simplest possible set of metadata to be included in the Zenodo platform with the possibility, for the community, to adopt and further develop/modify them. This article will describe in detail the formalisation and the digital formats adopted providing the related metadata templates developed within the projects.

An approach is proposed, using as case study: “Behind Livia’s villa” project. Its goal is to develop an application for expert users (archaeologists and architects), aimed at accessing various models created for a previous project (“Virtual Museum of Ancient Via Flaminia” [Forte et al. 2007]), and associated relevant metadata [Ronzino et al. ]. The original concept, in fact, was based on the creation of a VR immersive and narrative experience for the visitors of a museum (Roman National Museum). In this first version, two types of interactions were mixed (for experts with access to sources and level of reliability and for not experts with focus on storytelling). After a first assessment process (2009-2010), it was clear that the two levels of communication needed to be divided into two different applications. “Behind Livia’s Villa” was therefore specifically created for expert users whose interests are the acquisition of information on the single parts of the actual archaeological site (i.e. the rooms acquired with laser scanner technology) and of the reconstructed one (1st cent. AD hypothesis). A metadata xml container-schema was designed to enrich models and the granularity was based on the single models, as explained above. In order to understand if the users could efficiently access this information, using appropriately the application, interaction and interface, we have planned an evaluation session at Archeovirtual 2012 [Gockel et al2013]. The paper analyses results of this evaluation. It was succesfull in general but highlighted some issues about interaction with metadata. Main problem was that user seems to be confused on the use of metadata interface and on textual content: he seemed not properly focused on the information provided by metadata, but distracted. We were surprised because we have used as reference the model (interaction/interface/metadata) commonly adopted by 3d interactive applications dealing with collections of objects. This model proved to be not effective when applied to larger contexts. A new paradigm probably is needed, starting from expert users requirements. We have then considered Nubes project [De Luca et al 2011] We describe the first development steps we have undertaken to solve the above mentioned issues. The GUI infact was enriched to match the suggestions coming from evaluation. The metadata schema was also modified to refine the granularity from the room-based description to the single archaeologic object level (columns, paintings, protomes). The metadata schema was enriched to manage, retrieve and visualize the image sources within the 3d realtime environment.

Important international institutions such as ICOMOS and UNESCO, which represent the reference points for documentation and protection, have revised the definition of cultural heritage to include not only the elements of historical-artistic relevance and the testimonies of a civilization but also the environment around them. In other words, the meaning of cultural heritage has been extended to the concept of cultural landscape. This article tries to meet this last definition of cultural heritage: through an extensive 3D survey of the ancient city of Sarmizegetusa (National Historical Monument), it presents a new perspective for the documentation and representation of cultural landscape that includes not only the structures of the city but also the areas that have not been excavated yet, and the surrounding natural environment. The term “digital replica” is presented to define this new perspective. The article deals in detail with the whole digitization process and the tools used to obtain a digital replica of a Roman city deepening the integration between photogrammetry and computer graphics. The detailed description is intended to make the workflow reproducible by the scientific community. Besides, as a final remark, experimented optimization procedures and navigation tools designed to manage and explore large three-dimensional datasets will be illustrated.

It starts with a discussion on the philological correctness of a reconstruction based on different kind of sources, such as paintings, drawings, technical and literary texts, comparisons etc., and proceeds to explore the use of integrated 3D models (both relity-based and source-based) for improving the visitors experience. The reconstruction of the house was accomplished by means of analysing and developing the theoretical and methodological discussion faced in the last years within the scientific community. In particular, we tested the Extended Matrix (EM), a new tool able to keep track and represent the steps involved in the modelling of the source-based model, and adopted a structure that enables us to keep in consideration the different levels of certainity of our sources.

The Extended Matrix (EM) is a tool that extends the stratigraphic approach to the recording and managing of the re-constructive record: one of the goals of this research is to prove that the stratigraphic method, intended as chronological reading of a spatial context, is able to compose a complete and multidimensional re-constructive record through the EM. This approach can improve the quality of virtual reconstructions non only for scientific purposes but also in the industry of Virtual Museums and Digital Libraries.
