Coronavirus: Lockdown has given archaeology an unexpected boost with volunteers finding previously-unrecorded Roman, prehistoric and medieval sites from the comfort of their own homes
Lockdown has given archaeology an unexpected boost with volunteers finding previously unrecorded Roman, prehistoric and medieval sites from the comfort of their own homes.
In a project coordinated by a team at Exeter University, enthusiastic amateurs have been analysing images derived from Lidar data - laser technology used during aerial surveys to produce highly detailed topographical maps. Modern vegetation and buildings can be digitally removed, allowing archaeologists to look at the shape of the land surface to find the remains of archaeological earthworks.
The data is being systematically examined and cross-referenced with records of known archaeology and historic maps, meaning the total of new discoveries regularly changes.So far the team have found parts of two Roman roads, around 30 prehistoric or Roman large embanked settlement enclosures, and some 20 prehistoric burial mounds, as well as the remains of hundreds of medieval farms, field systems and quarries.
Project leader Dr Chris Smart, from the University of Exeter, said:"Ordinarily we would now be out in the field surveying archaeological sites with groups of volunteers, or preparing for our community excavations, but this is all now on hold.
