This anchor lies on the seabed in Eddrachillis Bay. The image is not one single photograph but has been created using photogrammetry techniques. The anchor is part of the 17th/ 18th century Drumbeg wreck site, now Scotland’s first Historic Marine Protected Area. It was surveyed by WA Coastal & Marine on behalf of Historic Scotland in the summer of 2012. Specialist photographic and photogrammetric techniques were applied to create an accurate 3D model of the site.
The idea for this case study came from Marine & Maritime – Challenges and Future Directions
This case study was originally part of the ScARF poster at the 2014 IfA conference. The entire poster can downloaded as a pdf
