La piattaforma GIS per lo scavo a Pompei (Regio VI, insulae 7 e 14; Regio V, insulae 3 e 4) : un modello di gestione informatizzata e di analisi interdisciplinare per l’interpretazione dei contesti di indagine e la valorizzazione del patrimonio archeologico

The main focus of this Research is the representation of archaeological data using GIS technology, focusing on the evolution of domestic spaces in Regiones V (insulae V,3 and V,4) and VI (insulae VI,7 and VI,14) at Pompeii. In this project, intra-site GIS is the central research framework for the interpretation of the investigated areas, where building activities succeeded since the Samnitic phase (IV-II cent. BC) to the final destruction of the roman colony in 79 AD. Spatial analysis and predictive models, performed by combining excavation data and architectural studies, provide a very wide and complex range of information, such as layers about chronological phases or about evidences’ distribution patterns, as well as 3D modeling. In this case study, GIS helps in understanding the formation process of archaeological stratigraphy as result of the changes known from the history of the ancient site; it offers the opportunity not merely for recording and managing data, but also for their reinterpretation. The advantages obtained by using GIS are both methodological and interpretative, since they consist in representing spatial-temporal relations, analyzing at a multiplicity of levels, as well as acting as a support for objective interpretative evaluations, realizing interactions between different archaeological disciplines. Other aspects developed concern digital photogrammetry and 3D modeling, in order to obtain precise and realistic 3D representations of wall-structures and also of the terrain (DTM). The GIS performed provides useful information, in consideration of the management of the Cultural Heritage, thus conceiving the complete perspective for interpreting such a complex area of investigation.
