In 2010, The Arctic Institute of North America and colleagues took upon the task of scanning Fort Conger for the purpose of restoration and documentation. Fort Conger is located in the arctic region of Canada, and was established in 1881 as an Arctic exploration camp. Due to the extreme environmental conditions, Fort Conger has a dark, yet scientifically significant past. The Lady Franklin Bay Expedition of the First International Polar Year scientific initiative was led by First Lieutenant Adolphus Greely and 25 members. The group was transporting a building to the site, provisions, and scientific equipment meant to last for two years of research. Unfortunately only 6 survived the retreat. Also, Robert Peary’s attempt to claim the North Pole had utilized the Fort.
The project utilized the Z+F Imager 5006i, phase-based laser scanner. The Imager 5006i was used to scan terrain and large cultural features such as the Peary huts. Also, Z+F LaserControl was utilized for registration of the point clouds. Due to the extreme polar conditions, it was a difficult project, but utilizing 3D laser scanning made the process quick and accurate. A total area of 34,500 m2 was recorded from 43 different scanner locations. Scans revealed great details such as staining caused by nails on wallboards in the Perry huts.
Fort Conger is currently at risk due to climate change, weather, wildlife and human activity. The point clouds will be used to support on-site conservation efforts and will also supplement earlier traditional documentation methods.
