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.

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.

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).

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.
