Integrated survey for the modeling of complex environments. La Grotta di San Michele Arcangelo a Olevano sul Tusciano, Salerno

The possibility of integrating digital technologies facilitates the documentation and, consequently, the management of complex environments such as the Hypogean Heritage. The Grotta di San Michele Arcangelo, a natural cave located in the municipality of Olevano sul Tusciano, in the province of Salerno, is being selected as a case study to test the integration of different digital surveying technologies. Through the combined use of SLAM-based techniques, used for the acquisition of the interior space, and LiDAR-UAV techniques, for the exterior, an integrated point cloud was obtained from which accurate geometric information could be extracted, necessary for three-dimensional modeling of the analysed environment. The purpose was to provide the academic community with updated multidimensional information of the hypogean scenarios, defining good practices for their application. The database becomes an essential tool for the understanding, monitoring and management of these complex environments and also lends itself to actions of valorisation and promotion of virtual accessibility to this heritage
