Mountain Hamlet Heritage Between Risk and Enhancement

This paper focuses on villages and hamlets on the mountain considered historical, cultural heritage. Due to their cultural and historical values, they need documentation, enhancement, and revaluation activities. The research aims to semantically and spatially describe minor historical centres such as hamlets affected by natural hazards and risk phenomena (landslide, avalanches, {\ldots}). In this domain, many actors and use cases are involved in different activities such as urban and landscape planning, restoration, tourism, etc. For this reason, it is necessary to develop a replicable and sharable workflow able to harmonise and integrate different sources (spatial, structured, unstructured, historical and so on) to document these centres thoroughly. A significant case study has been selected to apply the presented methodology. It is the hamlet of Pomieri, in the municipality of Prali (Piedmont Region, Alps, Germanasca Valley, Italy). Different documents about natural hazards phenomena have been investigated parallelly to semantic and ontologies sources. This method set the basis for developing a knowledge base, including further information on such centres subject to risk and needing documentation, restoration, preservation, maintenance and planning actions.
