We have a fully reconditioned and calibrated Trimble/Mensi GS200 3D Laser Scanner available for immediate purchase at a considerable discount from list price. See our Reconditioned Equipment list for more information and to contact us. We only have one of these scanners available, so first come, first served.

In a nutshell, the scanner is capable of 1000 points/second, +/-6mm accuracy at 50m, 3mrad @ 100m resolution and has ranging capability of up to 350m using OverScan. The scanner has a 360×60 degree field of view from a single station.

For examples of work undertaken with this scanner, see Brodick Castle Survey Completed, 3D Laser Scanning at Callanish Stone Circle and National Archaeology Day at Rievaulx Abbey.

We undertook some survey work for the Royal Commission on the Ancient and Historical Monuments of Scotland (RCAHMS) in Aberdeenshire. Both projects were commissioned to use 3D laser scanning to extract additional information from heavily weathered Ogham inscriptions and, in the process, we also clarified the interpretation of a Pictish symbol.

The two sites in question were the Pictish cross slab located in Fordoun and the Lang Stane of Auquhollie, near Stonehaven.

The slab at Fordoun features an inscription on the top-left corner and also two putative Ogham inscriptions, one down each side. All three inscriptions were scanned at extremely high resolution to help establish their meaning.

The Lang Stane was also completely scanned with extremely high resolution scanning used on the long Ogham inscription down one arris and on a section of the stone thought to feature two Pictish “double-disc” symbols. After visualisation, it was determined that the two symbols were in fact a single lobed “rectangle” symbol.
