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.
A multispectral image of a field

A technique borrowed from precision agriculture, this aerial survey method uses a cluster of light sensors tuned to specific light wavelengths or ‘bands’ to detect changes in plant health which aren’t visible to the human eye.

The data can be used by agronomists and foresters for a range of monitoring and inventorying procedures, for example identifying drainage problems, disease or invasive species. It can also be used as an archaeological prospection technique for detecting cropmarks that would otherwise be invisible, faint or unclear.


Our techniques

Learn more about the techniques that we use.

Aerial Photography and Videography

Aerial views provide unique, breath-taking perspectives, capturing assets, sites and landscapes as images, videos or photospheres. Perfect for reconnaissance surveys, settings assessments or promotional campaigns.

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.

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.
