 Geophysical survey (archaeology)

A geophysical survey in archaeology refers to a range of techniques used to identify and map archaeological features and sites without the need for excavation. These non-invasive methods involve measuring physical properties of the ground to detect anomalies or variations that may indicate the presence of archaeological materials, structures, or landscapes.
