Aerial LiDAR Survey & UAV Mapping Services
TerraDat has been mapping the world in three dimensions since the earliest days of close-range photogrammetry and terrestrial laser scanning. As drone technology matured, we were at the forefront of integrating airborne LiDAR — and today our UAV-mounted sensor represents … Read More
Brownfield Site Investigation using Geophysics
Most former industrial sites have a legacy of buried structural hazards and contamination. Geophysical surveys can detect buried targets without the need to excavate. Many industrial contaminants, such as salinisation by acids and hydrocarbon plumes, can leave a significant geophysical … Read More
Magnetics
The magnetic survey technique is based on mapping localised variations in the Earth’s magnetic field caused by sub-surface magnetic materials, which range from naturally occurring magnetic minerals to man-made ferrous objects. This leads to a wide range of applications, from … Read More
MASW (Surface Wave Surveys)
Multi-channel Analysis of Surface Waves (MASW) is a very useful method for investigating shallow geological structure and, in particular, the relative shear strength of subsurface materials. By incorporating density values for the local bedrock and overburden sediments it is possible … Read More
Electrical Resistivity Tomography (ERT)
The Resistivity technique is useful for characterising the sub-surface materials in terms of their electrical properties. Variations in electrical resistivity (or conductivity) typically correlate with variations in lithology, water saturation, fluid conductivity, porosity and permeability, which may be used to … Read More
Experienced Ground Radar (GPR) Company
TerraDat has been a GPR survey company since the technique evolved to a level where it could be applied to a wide range of applications over 20 years ago. Because the GPR method involves analysis of wave-form data, our experience … Read More
Peat Mapping using Geophysics (Peat Surveys)
Mapping peat is a common requirement for proposed developments such as wind farms and pipeline routes where they cross remote and/or sensitive areas. There are several geophysical methods that can provide plan and cross-sectional information to map the distribution of … Read More
Ground Conductivity (EM)
A ground conductivity or electromagnetic (EM) survey involves the generation of an EM field at the surface and subsequent measuring of the response as it propagates through the subsurface. The main components of the instrument are a transmitter coil (to … Read More
