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.

Our techniques

Learn more about the techniques that we use.

Photogrammetry

Uses high-resolution cameras to create accurate and detailed topographical maps, scaled plans and 3D models of assets, sites and landscapes for use in mapping, topographic survey, inspections and monitoring.

Aerial Reconnaissance

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.

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.
