From Pseudo-3D to full-resolution GPR imaging in archaeology: A complex Roman site in Lugo, Spain

Advanced ground-penetrating radar (GPR) imaging revealed intricate details of a Roman villa's architecture, including walls, apses, and chambers, at the UNESCO-listed Roman Walls of Lugo site in Spain. The study demonstrated that ultra-dense grid surveys significantly enhance the resolution and interpretability of 3D GPR data compared to pseudo-3D strategies. Conducted over two campaigns (May 2007 and July 2008), the research initially mapped a broad area using a pseudo-3D approach, which identified key features for further investigation. A subsequent ultra-dense grid survey focused on a smaller section, uncovering high-resolution images that provided unprecedented insights into the villa's structure. This case study underscores the importance of meticulous data acquisition in archaeological GPR surveys, particularly in complex semi-urban settings.
