The company operates a B2B professional services model with project-based contracts delivered to consulting engineers, civil engineering contractors, government bodies, and utility operators across the UK, with named clients including Network Rail, the Coal Authority, the Environment Agency, Skanska, Costain, Jacobs, Arcadis, WSP, Atkins, BWB, Edinburgh Council, and Harrow Council. Service verticals are Civil Engineering, Mining and Minerals, Rail, Energy, Utilities, and Building, with rail, mining, and civil engineering identified as primary segments. Pricing is project-based and not publicly disclosed, and the company extends its capabilities through strategic partnerships with Flodim, FlyThru, GeoSLAM, Formby Surveys, FC Geomatics, TerraDat, and Skeye (formerly Skycap).

Geoterra holds required industry accreditations including RICS, ICES, RISQS, SafeContractor, and ISO 9001, supporting tender eligibility for UK rail and government infrastructure work.

Core offering

Geoterra provides specialist geospatial engineering surveys for mapping land and infrastructure that cannot be safely accessed using conventional survey methods. When sites are hazardous, confined, or inaccessible, the company deploys advanced subsurface laser scanning, UAV/aerial LiDAR and photogrammetry, indoor and outdoor mobile mapping, and multibeam sonar technologies to capture accurate, georeferenced 3D survey data. Deliverables underpin risk assessment, remediation planning, construction delivery and long-term asset management for consulting engineers, civil contractors, government bodies and utility operators across the UK.

Product overview

Geoterra provides a unified suite of specialist geospatial engineering surveying services for mapping land and infrastructure in hazardous, confined, or inaccessible environments. The core offering centres on subsurface laser scanning (C-ALS for dry voids; multibeam sonar for submerged cavities), supported by aerial LiDAR and ortho-photogrammetry via UAV drones, indoor and outdoor mobile mapping using GeoSLAM systems, and terrestrial 3D laser scanning with Leica and Faro equipment. These survey capabilities are complemented by 3D modelling, visualisation, and Scan to BIM services for data processing, while HD CCTV surveys, measured building surveys, satellite and structural deformation monitoring, and expert witness services round out the portfolio. The company operates across civil engineering, mining and minerals, energy, utilities, building, and rail sectors, with strategic partnerships extending specific capabilities (Flodim for sonar, FlyThru for UAV operations, Formby Surveys for building surveys).
