The Discovery Programme has been surveying using terrestrial laser scanners since 2006. A Trimble / Mensi GS 101 (time of flight) instrument has been used extensively with excellent results, recording millions of high accuracy, high resolution x,y,z points to generate digital 3D representations of the surface of objects. As with many other forms of surveying technology, this type of scanner has proved to be very adaptable and has been applied to a wide range of archaeological tasks. The downloadable pdf (below) showcases examples of the sites surveyed and results obtained from the GS 101 which, after 6 years of productive service, has now been replaced by a Faro Focus 3D 120, phase-based instrument.
