Geomatics for Cultural Heritage conservation: integrated survey and 3D modeling

Purpose of this paper is to illustrate the contribution of geomatics studies in management and protection of Cultural Heritage assets. Architectural surveys, carried out by integrating traditional survey techniques with more innovative instruments, are fundamental to guide the different actors involved in conservation and restoration processes, as they allow them to get a complete and extensive knowledge of the survey object, at different levels of detail and scales of representation. The integration and elaboration of the different survey techniques are illustrated in this paper with reference to the case study of the Calci Charterhouse, unique for its historical, artistic and environmental value. Among the different studies that are performed based on integrated geomatics tools, an innovative application is here discussed, which refers to the generation of informative parametric models starting from point clouds acquired through survey, as the pipeline of a Scan-to-HBIM process.
