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.

Incorporating aerial imaging methods during ‘walkover’ surveys extends the visual range of the surveyor, allowing more information to be captured from angles that simply aren’t possible in a terrestrial visit. Areas that aren’t yet accessible on foot can also be surveyed over safely from the air.

This means surveys are not only more efficient, but the outputs are of a higher quality, including geotagged photos and video flythroughs. The results can lead to more informed decision-making in subsequent programme design, further saving time and costs by reducing the need for redeployments. This is particularly useful on large or complex schemes, or projects with specific time constraints and a need for detailed access planning.

Our techniques

Learn more about the techniques that we use.

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.

Multispectral Imaging

Primarily used in precision agriculture, environmental surveys and forestry, this specialised sensor can also detect cropmarks caused by archaeological and other subsurface features.

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.
