HBIM for restoration project and data management of a religious complex

The paper presents the first results of a research project aimed at digitizing the restoration process of the monastic complex of Santa Maria a Graiano, located in Fontecchio (AQ). The parametric model allows the management of heterogeneous data derived from multidisciplinary knowledge processes and facilitates data sharing. The representative modelling of the artefact after the damage caused by the 2009 earthquake, to which the planned restoration operations were linked, compared to the parametric model of the artefact after restoration, allowed cooperation between different professionals, in addition to the documentation of the work carried out. In this way, the model assumes a central role in the knowledge process but also the heritage management process as it facilitates the choice of conservation strategies to be implemented on the asset in future years and to preserve the memory of the interventions carried out, simplifying the maintenance process in the as-built phase.

Dynamic 3D model for decoding archaeological complexity of funerary contexts

Archaeological contexts are extremely dynamic, undergoing changes over time that profoundly alter the archaeological record, both due to intentional human manipulation and natural degradation phenomena. These post-depositional phenomena distort our perception of ancient contexts, often making it difficult to recognize the original arrangement and to understand what the archaeologist is analyzing. This aspect especially concerns the funerary contexts, like burials, which are subject to numerous natural or anthropogenic changes. This study shows how, by analyzing funerary contexts in a processual key and reconstructing them in a 3D environment, it is possible to simulate, to isolate, and to analyze post-depositional phenomena through metrically and morphologically correct 3D reconstructions. 3D simulation can be extremely accurate when parameters such as gravitational force is taken into account. The aim is to verify changes due to transformation phenomena. The goal is to create a sequence that shows the transformative processes of the burial, from the moment of deposition to the excavation phase.

Dimensional assessment in bioarchaeology applications: a preliminary study on quality controls in 3D printing of human skulls

In the last few years, 3D printing has been used in archaeology and cultural heritage fields for different purposes, i.e., research, conservation and access to museum exhibitions. Among the different technologies of 3D printing, e.g., stereolithography or selective laser sintering, this study focuses on the quality assessment of printed models using fused deposition modeling technology. To simulate an anatomical archaeological find, a cranial model assumed as a gold standard has been printed from computed tomography (CT) data of a human skull. Eight 3D printed (3DP) models have been reproduced and CT scanned with the same protocol in order to quantify their congruence with the gold standard through an objective measurement method based on image analysis. Preliminary results show an increasing percentage error as the degree of model detail increases, from 1% to 15%. The experimental results are discussed and commented also from a metrological point of view.

3D virtual restoration: from photogrammetric and 3D modeling techniques to integration with scientific documentation in a GIS environment

The contribution proposed here is linked to the doctoral research being carried out, which aims to develop a 3D GIS (Geographic Information System) platform that can integrate all the software necessary for the elaboration of a scientifically correct virtual restoration and at the same time can contain all the documentation relating to the intervention itself, the analyses carried out and the sources used. The contribution, therefore, will focus only on the specific case of the 3D virtual restoration of artefacts starting from the data coming from one of the case studies investigated, specifically a kotyle from the Etruscan excavation conducted, by the University of Tuscia, in the Monte Abatone necropolis in 2019, to show the potential of this project and possible further developments.

Satellite automatic extraction and characterization of looting features in the Peruvian desert

Archaeological looting is a known threat and causes irreversible damage to historical heritage. In Perù, looting of the grave robbers is a diffuse and ancient problem, starting in the first centuries of the Spanish colonization: the search for gold of the Conquistadores. The desert areas of the Peruvian southern and central coast are the most affected by the relentless plundering of archaeological sites. To counter this scourge, in recent years, many studies succeeded in monitoring the archaeological contexts via satellite remote sensing and automatic digital workflows. In this paper we propose a further step of these studies, with the presentation of an automatic workflow to extract and classify the superimposed looting pits of heavily disturbed sites, establishing a relative chronology of the illegal activities.

Multiple GPR surveys in urban area. The case of S. Giovanni in Laterano and S. Croce in Gerusalemme, as part of ERC Rome Transformed Project

The geophysical prospection is generally considered as the attempt to locate structures of archaeological interest buried in the natural subsoil, but in many cases, when applied in urban centers, this attempt could file due to the effect and disturbances caused by recent man-made structures in the subsoil, covering any signal related to possible archaeological structures. In the present paper the GPR surveys carried out in two urban archaeological sites in Roma, characterised by different targets and environmental conditions, are presented and discussed.

Multimodal 3D digitization of the megalithic complex of Borg in-Nadur (Malta): an archaeoastronomical perspective

The Maltese archipelago is home to megalithic structures of extraordinary interest for archaeo-astronomy. Some of those impressive prehistoric complexes have revealed significant architectural and topographic features reflecting a certain knowledge of the celestial bodies and astronomical phenomena by their ancient builders. While previous archaeo-astronomical studies of these Neolithic structures were primarily based on traditional methods, this paper presents an innovative approach for the case study of the Borg in-Nadur site. Through an ensemble of techniques, such as terrestrial laser scanning, aerial and terrestrial digital photogrammetry and 3D modeling, the prehistoric remains have been 3D digitized and inserted in a virtual environment to test archaeo-astronomical hypotheses via computer simulation.

Ground Penetrating Radar investigation at Roman Villas of Sabina Tiberina: the case of the villas of Montebuono and Cottanello (Rieti, Italy)

The development of geophysical exploration and techniques have proven to be of great help in identifying and classifying buried surfaces and for planning future excavation strategies. The purpose of this work is to detect the presence of buried structures (walls, floors, etc.) in unexplored areas of the Villa of St. Pietro ad Muricentum (Montebuono, Italy) and the Villa of Collesecco (Cottanello, Italy). Both areas were investigated with the Ground Penetrating Radar (GPR). The preliminary results show anomalies a few meters deep attributable to buried archaeological structures. These anomalies seem to be attributable, due to their shape and dimensions, to the presence of wall structures. Moreover, the maps obtained from the planimetric representation (time slices) of the Georadar reflections made it possible to follow the development, as the depth increased, of these structures and to reconstruct their reciprocal geometric correlation. This provides an overall view of the structures under investigation and provide useful guidance to archaeologists for the planning of excavation investigations.

Ground-penetrating Radar survey at the Basilica of Santa Caterina D'Alessandria (Galatina-Italy)

The basilica of Santa Caterina D Alessandria was built between 1369 and 1391, by order of Raimondello Orsini del Balzo. These, on one of his many journeys, returning from the Crusades, went as far as the summit of Mount Sinai to pay homage to the body of Saint Catherine. The building, on Raimondello s death in 1405, will be completed by his wife, Princess Maria d Enghien, and then by his son, Giovanni Antonio Orsini Del Balzo. A study, using ground penetrating radar tecnique (GPR) was undertaken inside the Basilica in order to investigate the oldest structure of the church. The GPR analysis showed a series of anomalies that could be related to the old plant of the basilica.
