Conclusions To recap, UAV-based surveys fll the gap between large-area airborne-based and ground-based magnetc surveys conducted by humans. In additon to the obvious advantage of being able to cover inaccessible areas, UAV surveys actually provide the highest resoluton for geophysical surveys and open up new possibilites for local geological interpretaton. They have advantages over ground-based surveys, which in theory could ofer greater resoluton but are hindered by their close proximity to superfcial sources that can potentally produce a dominant signal and obscure geological features. Man-based surveys also sufer from terrain topography and sensor oscillatons caused by walking, which introduce external noise. In contrast, UAVs can fy at an optmal minimum distance to maximise the spatal resoluton of the geologic signal by following a smooth linear path that minimises external noise. For example, we have successfully tested our system in diferent geological setngs, such as intramontane Apenninic basins or mud volcanoes in Sicily, in order to characterise the subsurface geometry.
