Stoehenge in High Definition
English Heritage is using a combination of modern 3D laser scanning and digital imaging technology to survey every inch of every stone that makes up Stonehenge to produce the most accurate digital model ever for the world famous prehistoric monument.
The survey includes all the visible faces of the standing and fallen stones of Stonehenge, including Station, Heel and Slaughter stones, as well as the top of the horizontal lintels which have never before been surveyed at this level of detail.
Despite the vast amount of archaeological activity and academic study into Stonehenge and its landscape over the centuries, relatively little is known about the lichen-covered surfaces of the sarsens and bluestones that make up the stone circle. The availability of high resolution laser scanners that can produce highly accurate surface models means that it is now possible to record details and irregularities on the stone surfaces down to a resolution of 0.5mm. It is also hoped that secrets hidden underneath the thick cover of lichens may be revealed in the analysis using sophisticated software.
