Geophysical Survey. Digital Imaging. Laser Scanning.
Technical Services include:
- Geophysical Survey
- Trial Trenching
- Digital Imaging
- Laser Scanning
We often compliment a Geophysical survey (which detects items below the surface) with field-walking and a metal detector survey to provide you with a detailed understanding of the archaeological potential of your site. This enables a targeted and cost-effective approach to any intrusive investigations that could be required.
A good geophysical survey informs decisions on the location, scale and necessity of any further, intrusive site investigation. We use the following methods:
- Gradiometer (magnetometer) survey. Often the most cost-effective method of non-intrusive investigation, enabling large areas to be covered quickly.
- Resistivity (resistance) survey and ground penetrating radar (GPR).
In some situations, Trail Trenching may be a more cost effective that a geophysical survey. Get in touch, to discuss the best methods for your individual case.
Digital Imaging & Laser Scanning: We provide the full range of digital imaging, including survey data, LiDAR and photogrammetry and recording relating to archaeology. We provide:
- maps, plans, sections and distribution plots of remains discovered during site investigations using GIS (Geographical Information System) – using survey data from fieldwork.
- floor plans, elevations or 3D visualisations (using Laser Scanning when needed) and photogrammetry – to create images of both archaeological remains and structures – using survey data from buildings.
- RTI (Reflectance Transformation Imaging) to analyse low relief objects, alongside the use of traditional photography and hand illustration to depict artefacts.
