The CDDV team split in two: one half working on the top of the heads, the other working around the base of the mountain and on the treacherous ‘tallus’ slope, consisting of dynamite-blown fragments of rock. Using a combination of scanners, and with a member of CyArk regularly checking scan data and letting the CDDV team know of gaps in the point cloud, they worked to document the entire carving in 3D. For the areas the team were unable to reach from either above or below, a specially developed tripod rig was lowered down the face of the mountain on ropes by members of the NPS Rope Access Team, with the CDDV scanner safely secured on one end. Once in place, the team was able to control the scanner remotely for a safe location. Manoeuvring the scanner was no easy task, but the results were well worth the effort. The whole team feels privileged to have taken part in this project and thankful for the enduring friendships made there. To The Heart of Neolithic Orkney After a short break, the CDDV team headed north to the Heart of Neolithic Orkney World Heritage Site in August 2010. There are several sites which make up the WHS, and the aim was to laser scan all within the two week fieldwork phase: Maeshowe chambered tomb, Skara Brae village, the Ring of Brodgar, the Stones of Stenness, the Barnhouse Stone and the Watch Stone. Not only was the team laser scanning the monuments themselves, but also the detailed Viking inscriptions present within Maeshowe and the Neolithic carvings at Skara Brae. The team also carried out a detailed traditional survey, to tie into the laser data and increase the overall accuracy of the data collected. New challenges faced the team on Orkney while carrying out the fieldwork; of course, the unpredictable Scottish summer weather was at times an issue, and the clouds of midges almost got the better of the team at Ring of Brodgar! There was also the issue of site opening hours: twilight tours at Maeshowe meant the team working on the interior scans had to work a few night shifts! Despite these issues, the project went very well, and the team was spurred on by the great reception given by the Orcadian people and by visitors to the sites. The team also had the opportunity to put to use a few new pieces of equipment, including a telescopic tripod, which allowed scans at a height of 4m: this was a great advantage when documenting the standing stones at Stenness and Ring of Brodgar. The laser scan data collected on Orkney will have many practical uses for the conservation and maintenance of the sites. It will allow for coastal erosion monitoring at Skara Brae and condition monitoring of the delicate carvings and inscriptions. Architectural drawings and plans will be produced from the laser scans for sites such as Maeshowe, which will assist our architects with detailed conservation plans. The data will also be used to create virtual tours and to explain the evolution of the structures over time. Virtual reality access to sites such as House 7 at Skara Brae, which has not been open to the public for many years, will now be possible. Indian Adventure Also in August 2010, a small team of CDDV representatives travelled to India to meet with the Archaeological Survey of India (ASI) and to visit potential Orkney 3D digital documentation The Orkney team 8 FOCUS | Historic Scotland 2011
Detail, Rani Ki Vav, Gujarat, India. Rani Ki Vav, Gujarat, India, view from the top sites for the second international project. Several breathtaking sites in Gujarat were viewed, including a Sun Temple, the Champaner Pavagadh Archaeological Park and Rani Ki Vav (The Queen’s Step Well). After careful consideration of the technical and logistical issues each site posed, and in discussion with the ASI and the Scottish Government, it was decided that Rani Ki Vav would be the second international Scottish Ten site. Rani Ki Vav was constructed around 1050 A.D. and served as a communal water well. It is a fantastic construction, descending some 27m below ground level, via a series of stepped terraces, each intricately adorned with carvings from Hindu legend and mythology. The step well was excavated some 50 years ago, and is currently on the UNESCO Tentative World Heritage List. The level of detail to record will be incredibly challenging within the timeframe for the fieldwork phase and there are many safety considerations as the terraces face onto the open well below. However, we are confident that by utilising novel 3D recording technologies and by adapting our existing kit, we can achieve great results and produce stunning visualizations, helping to generate the global profile that this wonderful site deserves. The team will be travelling to India in March 2011 to 3D survey fieldwork programme. For those who have not yet visited the site, there is information on the project and its origins, the technology used, the sites involved, showcase galleries of scanning work, blogs and initial results. Updates are constantly added, so please do check back regularly: www.scottishten.org As we love to embrace all new forms of digital technology, we have also been spreading the word on the Scottish Ten via social networking sites, Tweeting all the way from Orkney and India: www.twitter.com/ scottishten. Our digital animations are available to view on the Official Historic Scotland You Tube channel: www. youtube.com/user/historicscotlandtv, and images on Flickr: www.flickr.com/photos/historicscotland Do follow our progress on both our main Scottish Ten website and our Tweets. With fieldwork in India and St Kilda forthcoming, 2011 will surely be as busy and exciting a year for The Scottish Ten as 2010 has been! Digital Updates The official Scottish Ten website was launched in late August 2010 and has to date received over 15,000 hits: a sure sign of the interest the project is generating.
