Li Sou
I am an archaeologist and PhD candidate at the University of Bradford, on the AHRC’s Collaborative Doctoral Partnership scheme. My partner institution is Historic Environment Scotland. My research is on the application of digital documentation methods on three well-known Iron Age brochs on Shetland; Jarlshof, Mousa and Old Scatness. Using the latest 3D imaging techniques (laser scanning and SFM photogrammetry), I am comparing these new datasets to existing archives and historical records of the brochs, to better understand, disseminate and preserve these important monuments.
My research interests include geospatial imaging, remote sensing and its application in archaeology, the dissemination of heritage and archaeology to non-specialists and Later Prehistory, with a particular emphasis on monuments of the British Iron Age.
My undergraduate research (at Durham University) focussed on digital analysis of Neo-Assyrian carved stone sculptures. My Masters dissertation examined the historiographical interpretations and understandings of British oppida sites from Historic Environment Records (HERs) across Britain, and how past trends have influenced modern understandings of these monuments.
Supervisors: Prof Andrew Wilson (UoB), Dr Steve Dockrill (UoB), Dr Lyn Wilson (HES), and Dr Val Turner (Shetland Amenity Trust)

Papers by Li Sou
Both laser scanning and photography for structure-from-motion (SFM) photogrammetry were conducted on site, and 3D outputs, including 3D PDFs, Autodesk ReCap projects and OBJ files, were produced. From these outputs, it was possible to analyse the carved details on some of the stonework in greater detail using polynomial texture mapping (PTM), enhancing our understanding of these monuments and providing scope for further research.
Some basic stereo photogrammetric recording is undertaken for stonework, however little has been processed (Harrison 2016, pers. comm.). A new visitor centre for Rievaulx Abbey was completed in spring 2016, resulting in the permanent move of several objects associated with the site from the stores to new displays. With this development, the curatorial team at Helmsley decided to investigate whether Structure-from-Motion (SFM) photogrammetry could be a suitable means of recording artefactual data to meet their different needs for imagery. The CIfA placement holder in Geospatial Investigation Techniques at Historic England was tasked with creating 3D data outputs from images taken of different Rievaulx artefacts, for English Heritage’s curatorial team to assess for their suitability for record keeping, artefact analyses, conservation records, online and print publication, education, and public displays.
A programme of recording was undertaken by Li Sou, CIfA Specialist Placement in Geospatial Investigation Techniques, and Paul Bryan, Geospatial Imaging Manager. Within the castle keep a series of reliefs, known as the Prisoners’ Carvings, and a medieval door covered in etchings, were laser scanned, photographed and filmed. The datasets were then compared to examine the detail and quality of their outputs, to determine each technique’s suitability for recording such historic carvings. Additionally, photographic recording for SFM photogrammetry was undertaken for a Roman altar stone, medieval and postmedieval graffiti and carvings across the castle complex, to produce 3D models as a record of their current condition.
While the use of colour has been recognised (e.g. Cohen & Kangas 2010), few pigments have been subject to analysis (but see Verri et al. 2009), and a limited number of colour schemes have been reconstructed. Yet the original polychrome appearance of the reliefs would have been dramatically different from their present monochrome condition, suggesting alternative experiences and meanings. This research therefore aims to consider which colours were most frequently used, which features were most often painted and whether there was variation in the use of colour over time.
