Magnetic surveying is a widely used and cost-efficient remote sensing method for archaeology. Traditional magnetic surveying was conducted as ground or airborne surveys, which are cheap and provide large-scale consistent data coverage, respectively.
However, ground surveys are often incomplete and slow, whereas airborne surveys suffer from being inflexible, expensive and characterized by a reduced signal-to-noise ratio, due to increased sensor-to-source distance.
With the rise of reliable and affordable survey-grade Unmanned Aerial Vehicles (UAVs), and the developments of light-weight fluxgate magnetometers, magnetic measurements with an unmanned aerial vehicle (UAV) are ideal for filling the gap between ground and airborne magnetic surveying.
