DATI 3D E COSTRUITO ARCHEOLOGICO: LIMITI E POTENZIALITÀ DI BIM E GIS E NUOVE PROSPETTIVE PER LA CONSERVA ZIONE A POMPEI

3d data and archaeological building: limits and potential of bim and gis and new perspectives for conservation in Pompeii · In recent decades, three-dimensional survey technologies, such as laser scanning and photogrammetry, have revolutionized the documentation of archaeological sites, introducing new challenges in the management and enhancement of 3D data. In response, tools like gis (Geographic Information System) and bim (Building Information Modeling) have gained traction in the field of cultural heritage, offering integrated approaches to the conservation and analysis of ancient built environments. gis enables the spatial and temporal management of information, while bim, in its hbim (Historical/Heritage bim) form, provides detailed and semantically rich informational models. However, interoperability between these systems remains limited, especially in the archaeological domain, due to the semantic and structural complexity of the data. The case of Pompeii, through the initiative of the Knowledge Plan and the development of the SiPompei and Open Pompeii platforms, stands as a prominent example of both the potential and challenges in managing three-dimensional data. The big_smaart project aims to overcome these limitations by proposing an integrated gisbim system based on ontologies specific to archaeological heritage, particularly for Vesuvian architecture, with the goal of building a semantic and interoperable information archive to support the conservation, management, and enhancement of ancient cities.
