A ground penetrating radar prospection campaign completed in 2019 at the eastern end of the Roman small town of Bridiers in La Souterraine (Creuse, France), in a context of granite soil, revealed the presence of a previously unknown residential area covering roughly 0.8 ha (Baret, 2019) (Fig. 1). The prospection was carried out and interpreted by AnalyseGC (G. Caraire and T. Jubeau). The choice of a 200 MHz GPR StreamX, from IDS, for the survey was determined by its “multi-channel” configuration, which allows the simultaneous recording of seven radargrams covering nearly one metre in width (one every 12 cm). The GPR data were positioned using an RTK (Real Time Kinematic) RS+ GPS from Emlid. The RTK base was readjusted using RTKLIB software and data from the IGN permanent GNSS network.
