Photogrammetric survey and 3D GIS management of mesh in the integrated investigation of complex sites. The case study of the church of Santa Maria in Cesoni

This paper illustrates the results of an experimentation carried out by a group of multidisciplinary researchers from the ITC-CNR of L'Aquila and of archaeologists and engineers from the University of L'Aquila. This research project is based on the analysis of architectural and archaeological artefacts (the state of conservation of the artefacts, seismic vulnerability, stratigraphic analysis, construction phases) using methods linked to innovative digital technologies such as digital photogrammetric restitution, based on Structure from Motion (SfM) algorithms and the generation of photorealistic textures. The innovative methodological approach specifically refers to the management of archaeological data concerning the state of conservation of structures, damages and to their seismic vulnerability in a 3D GIS environment, with particular attention to three-dimensional stratigraphic readings of the artefacts.
