Gathering GPR Inspections and UAV Survey in Cultural Heritage Documentation Context

The archaeological researches and more generally the Cultural Heritage (CH) documentation and conservation activities have been favourably disposed to the use of new technologies, with renewed and increasing interest in the use of integrated techniques. In the field of Geomatics the advent of advanced technologies has allowed and facilitated multidisciplinary studies as well as combined approaches to the documentation in various contexts. The production of spatially located data (e.g. from active or passive sensors placed in different system segments, from terrestrial to aerial to satellite position) and their interoperability from different source, with the help of Geographic Information Systems (GIS), were then made easier. The work has the aim of investigating the integration of multiple data derived from aerial photogrammetry products through Unmanned Aerial Vehicles (UAV) survey, from geophysical Ground Penetrating Radar (GPR) prospection technique and analysis of historical ma ps. An archaeological area in the south of Piedmont (Italy), next to the ancient Roman settlement of Pollentia, has been the test case. The present fulfilled test was objected to exclude ancient presences, although this type of workflow is generally aimed to analyse and compare results in order to formulate some hypothesis about the potential presence of submerged elements or built substructures in the investigated area.
