Integrated Digital Survey for the Knowledge of the Seismic Damage and to Secure a Building. The Church of Santa Maria in Via in Camerino (MC). l rilievo strumentale integrato per la conoscenza dei danni e la messa in sicurezza. Il caso della chiesa di Santa Maria in Via a Camerino (MC)

Knowledge is the first step when taking any action on a historical building. In particular, the first necessary activity consists in carrying out a careful scientific geometrical/architectural survey of the structure. This is even more important if the building has been damaged due to seismic events and therefore contains collapsed portions or areas that are partially accessible or difficult to access. In order to initiate a survey in such circumstances, it is necessary to adopt an “integrated” approach based on the use of both terrestrial (3D laser scans, photogrammetry) and aerial (drones) digital tools. The present contribution illustrates the methodological path followed in the case of the Church of Santa Maria in Via, situated in the historical centre of Camerino, which was severely damaged following the earthquakes in October 2016. In particular, the survey method adopted aimed to obtain specific 2D and 3D representations to document the type and extent of damage to the building with an adequate level of detail. This was done by instituting the appropriate graphical documentation necessary to design adequate systems to secure the building.
