Analysing archaeological field data

Archaeological field data are three-dimensional. The archaeological record can be understood as a three-dimensional puzzle where relative position and morphology are crucial to understanding the past of a given site. Archaeological field data are now frequently born digital, with everything from iPads to GPS directly implicated in the selection (and destruction), capture and organisation of archaeological information. Graphical environments enable us to combine information from landscape survey, remote sensing, geophysics, building and topographic survey, and find locations into a single environment and hence to develop interpretations based on location. We cannot replicate the artefacts and the pre-excavation contexts but three-dimensional, graphical computing can bring us significantly closer than other modes of representation.

In the ACRG we use three-dimensional techniques in a wide range of our fieldwork. Particular examples include:

• AHRC Portus Project. This project includes a great deal of 3D on site data capture. We use a range of methods for integrating geophysical, excavation and other information.
• The RCUK Patina project is examining modes of digital expression on site and the impact of this on research practice.
• Tom Frankland (PhD student) is studying digital field practice and alternative augmented reality methods for use in the field.
• Archaeological Prospection Services of Southampton use integrated geophysical techniques on sites all over the world, and visualise these using graphical techniques.
