Earth Resistance (ER)
Measures the difficulty of passing an electric current through the ground. Effective for detecting features with different moisture content from the surrounding soil, such as foundation remains and ditches.
Incorporating aerial imaging during ‘walkover’ surveys extends the visual range of the surveyor, allowing reconnaissance to be carried out more safely and efficiently, with vastly more informative visual outputs.
