Scanning and visualization of Roman Adriatic townscapes

Abstract

Since 2000 a team from Ghent University has achieved intensive non-invasive intra-site prospections on four abandoned Roman towns in central Adriatic Italy (Marche Region): the coastal colony of Potentia and the inland municipia of Ricina, Trea and Septempeda. These urban surveys include total coverage geophysical prospections (such as GPR, geomagnetic and earth resistance approaches), low altitude aerial photography (including NIR photography with drone and helikite), geomorphological augerings, surface artifact collection, and micro-topographical field measurements. A GIS-based integration of all survey data, maps and re-studied legacy data has procured a formidable database for the computer-aided digital 3D mapping and interpretation of these complex ancient sites. The methodological acquisitions and archaeological results not only contribute to the understanding of Roman urbanization in this part of Italy, but also support and innovate the use of integrated approaches to geospatial mapping and analysis of ancient urban environments. Based on earlier experiences with 3D visualizations of the abandoned Roman town of Ammaia in Lusitania, as part of the EC funded Project ‘Radiography of the Past’ (http://www2.radiopast.eu/), the project in Adriatic Italy moves now towards presenting the new data in digital formats that allow specialists from archaeology and cultural heritage management, as well as the wider public to immerse into the visual world of Roman Late Republican and Imperial townscapes of a whole valley and its coastal environment.
