Unmanned Aerial Vehicles have become widely adopted platforms for geophysical investigations. In recent years, several geophysical sensors, including magnetometers, ground penetrating radars, hyperspectral cameras and thermal cameras, have been developed for drone-based deployment, thus enhancing the effectiveness of geophysical surveys. This work presents a multi-geophysical survey conducted to test two drone-based geophysical systems, namely, the MagNimbus magnetometer system and the Zond Aereo LF GPR system. The survey was carried out at the Altopiano di Verteglia (Montella, AV - Italy) in the Southern Apennines for investigating near-surface buried metallic pipes. The knowledge of the area makes it an ideal location for our tests, allowing us to compare the results associated with different physical parameters of the target, operating with different drone-based geophysical technologies and configurations, and understand how the collected data can be used to address environmental challenges.
