Callanish

Archaeoptics, a team of scientists and archaeologists, conducted the digital scan, hailed as a major advance in archaeological techniques, which produced computerised three-dimensional images and analysis of the stones.
The work will be used to produce educational material on the stones and shed light on their position within the greater Callanish complex and current archaeo-astronomical theories.
Alastair Carty, of Archaeoptics, said: “This is the most accurate survey of the site carried out to date.
“The technique is basically a device which measures 1000 points per second providing full 3D dimensions similar to existing surveying techniques but far, far more accurate. It also builds a dense 3D model. The model could be used to create virtual astronomical events.
“We hope to help create a video or DVD that can add information about the stones through a fully interactive 3D model. As my equipment measures the area, an image builds up on the screen and you can immediately see what’s going on.”
