photogrammetric or structure from motion techniques. Photogrammetry and 3D modelling has not been confined to structures. The skeletons from a late Roman and Saxon cemetery at Cherry Hinton in Cambridge, excavated by OAE, were recorded using photogrammetry. UAVs have been used by OAN to map extensive landscapes, such as the former Greenside lead mine in the Lake District. The combination of a UAV, photogrammetry and detailed orthophotos captured the complex lead mining landscape, which comprised spoil heaps, mine shafts, wheel pits, engine houses, and trackways, among other remains. Oxford Archaeology uses a hand-held laser scanner that has an inertial measurement unit (IMU) and a small scanner mounted on top. These features allow the scanner to fix its location precisely and the surveyor to record the interior of a building in as much time as it takes to walk through it. Combining photogrammetry with the laser scanner also allows whole buildings to be recorded in 3D. OAN has employed the hand-held laser scanner to record Daisy Mill, a former Victorian cotton mill in south Manchester, and Lion Mill, a corn mill in Stonyhurst in Lancashire. Charitable aims and outreach A registered charitable trust with educational aims, OA has various outreach and community archaeology projects running alongside its commercial work. All three offices engage in outreach and public engagement, with a particular focus at OAE. Recent highlights include the volunteer dig at Maryport Roman settlement and the Jigsaw Cambridgeshire project which trains and supports local archaeology societies across Cambridgeshire References External links Oxford Archaeology group website OA Library Further reading Darvill, T (ed.)
