GNGTS 2023 - Atti del 41° Convegno Nazionale

Session 3.2 - POSTER GNGTS 2023 The interpolation was performed with the Inverse Distance Weighting method, proposed by Shepard (1968), which uses a weighted average based on the distance of the points from the observation point. Figure 2 shows the 3D model obtained. 1. Conclusions The built 3D GPR model shows numerous linear anomalies. Most of these anomalies are superficial (up to 1 meter deep) and probably due to underground pipes, also confirmed by some manhole covers in the square. However, some anomalies are not related to the presence of underservices and their width (even 2 meters) is not compatible with the presence of pipes. The archaeologists will evaluate which of these anomalies deserve to be investigated with a direct excavation essay. References Baker G. S., Jordan T.
