Electromagnetic induction

Electromagnetic induction measurements, as demonstrated by the ORBit research group of Ghent University, can be successfully used to efficiently and non-invasively map physical properties of the soil and buried archaeology. Using latest mobile proximal soil sensing technology, such as the Dualem sensors, it has become possible to investigate soil properties, such as apparent conductivity and magnetic susceptibility, across large areas in high resolution.

This geoarchaeological approach ideally complements the magnetic and GPR prospection methods. It can be further used successfully in areas were the penetration depth of the GPR method is limited and provides 3D information about the geological underground.

Remote sensing methods

Remote sensing referes to all aerial sensor technologies, in contrast to the ground based geophysical prospection methods.

Aerial photography

Laser scanning

Airborne imaging spectroscopy

Geophysical prospection methods

Near-surface geophysical prospection can under suitable conditions be used to gain information about the physical properties of the subsurface.

Magnetic prospection

Ground penetrating radar (GPR)

Electromagnetic induction (EMI)
