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.

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 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.

Magnetometry

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