Earth Resistivity Tomography (ERT)

Multiple earth resistance profile measurements are fused to create 2D sections and 3D profiles of electrical resistivity through the ground, commonly used to determine the depth of known features.
The team at work

This technique is similar to earth resistance, but uses lines of fixed electrodes to create 2D slices and 3D views of changes in earth resistance at different depths. Typically, this can be used to model the depth and shape of known features, such as buried landforms or extraction pits.

Earth Resistivity Tomography (ERT)

Multiple earth resistance profile measurements are fused to create 2D sections and 3D profiles of electrical resistivity through the ground, commonly used to determine the depth of known features.

Magnetic Susceptibility

Measures the ease with which a material can be magnetised. Effective for detecting features with magnetic contrast from the surrounding soil, including burnt features, pits, ditches, and intra-site activity zones.

Electromagnetic Conductivity (EM)

Measures the ease of which current flow can be induced in material. Effective for detecting conductive features, such as geomorphology and subsurface landforms, ditches and earthworks.
