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.

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.

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.

Magnetometry

Measures the ambient magnetic field strength. Effective for detecting features with magnetic contrast from the surrounding soil, including burnt features, pits and ditches.

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.
