Summary
The project tests the novel technique of 3D laser scanning
for the recording of prehistoric rock carvings. The main objectives is
to assess the reliability, accuracy and precision of this technique for
recording purposes and to evaluate its capacity to discover new carved
motifs invisible to the naked eye. In addition the project will assess
the potential of the technology for monitoring rock surface decay, and
examine its value as a visualisation and presentation tool. The study
was undertaken at two stone circles in Cumbria
which exhibit megalithic art: Castlerigg and Long Meg and
Her Daughters, on the Copt Howe panel also in Cumbria, and the Horseshoe
Rock in Northumberland.
