Joined Interpretation of Buried Anomalies from Ground Penetrating Radar Data and Endoscopic Tests

This paper presents ground penetrating radar (GPR) results joined with and back‐upped by endoscopic tests performed in two churches. The aim of this work is to show how the endoscopic tests can help the interpretation of the achieved GPR images, and this will be shown with respect to two case histories in southern Italy. The usefulness of the endoscopic tests depends on the kind of targets, but is expected to be particularly useful in cases of buried cavities, where information about the volume and the possible past use of the cavity can be retrieved. In the examined cases, the endoscopic tests allowed the presence of three cavities to be established, helping also in the interpretation of their possible nature and use, even if the endoscopic probe was not gyroscopic nor equipped with a laser for the precise measure of the distances.
