3D Geophysical model of the subsurface
TerraDat is a European leader in state-of-the-art Geophysical Site Investigation, Geological Mapping and 3D Geodetic Laser Scanning. Our work is carried out using non-invasive methods with the very latest equipment to produce the highest quality solution for the Client.
We have extensive experience in all areas of subsurface mapping in relation to the Geotechnical, Civil Engineering, Environmental, Water Resource and Mineral Industries. We also have an ever increasing involvement in the Energy Sector.
Our services are commissioned by commercial organisations and by the public sector, wherever there is a requirement to gain an in-depth understanding of the subsurface. We work at all scales ranging from broad regional studies (water resources, geothermal energy, gravity mapping, mineral exploration, geological modelling) through major engineering projects (pipeline routes, tunnels, power station installations, shallow hydrocarbon exploration) down to local site investigations (contaminated land, UXO, archaeology, geotechnical studies).
In addition to our geophysical survey capabilities, we have a specialist survey division for creation of 3-dimensional models using photogrammetry. Applications include heritage building models, forensic crime and accident scene reconstructions and geotechnical mapping.
TerraDat is now offering an exciting new service involving the installation and management of a novel ground displacement and structural monitoring. This has applications in slope stability monitoring, civil structure (roads, railways, tunnels etc.) monitoring and in pre-empting geohazards. The system uses a flexible array of multiple gravity sensors that are able to output their absolute 3D position in real time.
