Ground Penetrating Radar (GPR)

Measures the travel time of reflected high-frequency electromagnetic radiation. Effective for detecting abrupt interface changes and voids, for example foundation remains, graves, burial chambers and cellars.

Ground-penetrating radar (GPR) measures the travel time of reflected high-frequency electromagnetic radiation. Effective for detecting abrupt interfaces between materials and fills. Typical example targets include foundation remains, graves, chambers and voids.

Magnitude Surveys can deploy hand-held or motorised, single-channel, multi-channel, multi-frequency or stepped-frequency systems according to the required survey target, depth, resolution and coverage.

Our techniques

Learn more about the techniques that we use.

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.

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.

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.
