Ground-penetrating radar survey at Falerii Novi: a new approach to the study of Roman cities
Abstract
Our understanding of Roman urbanism relies on evidence from a few extensively investigated sites, such as Pompeii and Ostia, which are unrepresentative of the full variety of Roman towns. This article presents the results of the first high-resolution GPR survey of a complete Roman town—Falerii Novi, in Lazio, Italy. The authors review the methods deployed and provide an overview of the results, including discussion of a case-study area within the town. They demonstrate how this type of survey has the potential to revolutionise archaeological studies of urban sites, while also challenging current methods of analysing and publishing large-scale GPR datasets.
[-]Ground-penetrating radar (GPR) is a reliable method that provides high-resolution 3D images of buried structures. It relies on the reflection of electromagnetic (radio) waves at transitions between materials of a different dielectric permittivity. The amplitudes and travel times of the reflected waves are measured, resulting in vertical radargrams or profiles. Using several parallel radargrams, horizontal slices at different depths (‘time-slices’ or ‘depth-slices’) can be created. Whereas traditionally a small, single antenna has been moved manually over the ground surface, over the last decade, multi-channel GPR arrays have been developed (Linford et al. 2015)—usually now towed by an all-terrain vehicle. Combined with real-time positioning using a global navigation satellite system receiver or a tracking total station, GPR now allows for rapid survey of large areas, while maintaining a high sample density (Grasmueck et al. 2005).
