From pseudo‐3D to full‐resolution GPR imaging of a complex Roman site

A high-resolution ground-penetrating radar (GPR) survey of the Roman Walls of Lugo, Spain, revealed intricate details of a Roman villa previously obscured by a pseudo-3D imaging strategy. The study demonstrated that ultra-dense grid data acquisition—with GPR lines spaced just 0.1 meters apart—could capture fine structures such as walls, apses, and chambers with unprecedented clarity. Initial surveys in May 2007 used a more spaced grid (0.5 m), which only identified broad areas of interest. A follow-up survey in July 2008, focusing on a smaller area with ultra-dense sampling, uncovered the villa's full architectural complexity. This case highlights how advanced GPR techniques can significantly enhance archaeological interpretations in complex semi-urban environments.
