Protect your assets from the ground up
Ground and infrastructure monitoring from experts at Imperial College London and Royal Holloway
Ground Evolution Monitoring (GEM) is an independent consultancy built on a decade of research and development at Imperial College London and Royal Holloway University of London. We help organisations detect and manage earth surface and infrastructure movement with our unrivalled proprietary software. Using satellite Interferometric Synthetic Aperture Radar (InSAR), we provide clear, reliable insights into how the ground and infrastructure behave over time, so you can act early, reduce risk and protect assets with confidence.

Bespoke ground and infrastructure monitoring services
Understand how your site has moved over time. We analyse satellite data from 2014 onwards, to identify historic movement patterns and hidden risks.
Track ground and infrastructure movement with millimetric precision, receiving regular updates and early warning alerts when it matters.
We collaborate with universities, research institutes, and industry to advance InSAR capabilities and solve complex monitoring challenges.
Receive detailed, expert-led insights and reports supported by geotechnical and structural analysis that you can rely on.
High quality and informative deliverables
including map figures and time-series displacement graphs for your site
Buildings, infrastructure, roads, bridges, and other hard surfaces at your site act as persistent scatterers that reflect the satellite radar signal, to reveal their patterns of movement.
Each of these persistent scatterers provides a comprehensive time-series of historical and current movements, enabling you to understand ground and infrastructure movement at your site over time.
