H-GIS-BIM Integration as a Knowledge-Making Tool for Heritage in Italian Marginal Areas

This research investigates the development of integrated knowledge systems for built heritage located in Italian Inner Areas, marginal territories characterised by socio-economic fragility and the progressive weakening of traditional settlement systems. Within these contexts, built heritage is deeply interconnected with the landscape as a result of long-standing interaction processes between man and territory. Yet it is often affected by limited, fragmented information and inadequate digital management frameworks. This study addresses these issues by developing a methodological approach grounded in multidisciplinary, multiscalar, transcalar, and diachronic principles to reconnect territorial and architectural dimensions within a unified interpretative framework. The Alpine municipality of Dosso del Liro (Northern Italy) was selected as a representative case study for testing the applicability of an integrated H-GIS-BIM workflow under conditions typical of marginal contexts. The research combines desk-based and field-based investigations. Information was organised with regard to the historical and diachronic features of assets and then integrated into a digital environment developed using GIS, HBIM, and conversion workflows. The results demonstrate the accessibility of H-GIS-BIM strategies through a methodological approach and their support for enriching analyses of diffuse heritage, while also highlighting current limitations regarding workflow, interoperability, semantic preservation, and dynamic data updating.
