Exploring Ephemeral Features with Ground-Penetrating Radar: An Approach to Roman Military Camps

This paper addresses an experimental approach to the archaeological study of Roman camps in NW Iberia using ground-penetrating radar (henceforth GPR). The main goal is explore capabilities GPR extract datasets from ephemeral features, such as temporary or siege works, among others. information aims maximise data available before excavation, orienting it areas that could provide good results terms feature detection and contrast between soil matrix deposits. explores potential volumetric visualisation improve our understanding four sites: Alto da Raia (Montalegre, Portugal–Calvos de Randín, Spain), Sueros Cepeda (Villamejil, Los Andinales (Villsandino, Villa María (Sasamón, Spain). Despite focus this paper, other survey techniques (namely LiDAR, aerial photography, magnetometry) were used combination with GPR. Further excavation sites provided ground truthing for all remotely gathered.
