State-of-the-Art Surveying Technology

We pride ourselves on our efficient surveying, utilising the latest towed geophysical systems that are both high-speed and environmentally considerate. Our magnetic gradiometry, Ground Penetrating Radar (GPR), and Electromagnetic surveys use all-terrain vehicles designed for minimal ecological impact, allowing maximum coverage and resolution while significantly reducing time and costs.

We pioneered aerial imaging long before the advent of drone technology, honing our skills using blimps, kites, and masts. Fortunately, drones have simplified this process, and we have a wide range of drone-based technologies to assist any site investigation.

Once fieldwork is complete, our team use the latest GIS software to generate detailed maps that highlight geophysical anomalies, placing them in their wider regional archaeological setting. These features are then overlain on digital terrain models to allow consideration of buried archaeology within its broader topographic context. Our detailed reports offer in-depth analysis of potential archaeological sites, ensuring Clients are well-informed of their project's subsurface conditions.
