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.

Electromagnetic Conductivity (EM) measures the ease with which electrical current can be induced in a material.

Effective for conductive features, such as geomorphological features, ditches and earthworks. Our equipment can be configured as a wide array to locate geomorphological features at depth, or as a smaller array to detect finer and shallower features such as earthworks and ditches.

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.

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.

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.
