This dataset consists of files that can be used to view 3D models of two rock piles adjacent to ‘The Bear Trap’, a Norse ruin at the western end of the Nuussuaq Peninsula in NW Greenland. 3D models of the first rock pile (rockpile01) were created from 326 photographs and the second model (rockpile02) used 267 images. Images were processed using Agisoft Metashape Pro v1.7. A 24.3 megapixel Sony a5100 APS-C mirrorless camera fitted with a 24 mm lens was used to acquire ground-level imagery of the rock piles. The settings used in Metashape can be found in the processing reports (pdf files) for each rock pile. The image survey was conducted as part of the Vaigat Iceberg-Microbial Oil Degradation and Archaeological Heritage Investigation (VIMOA) project, which was funded by the Danish Centre for Marine Research and supported by the Arctic Research Centre at Aarhus University, the National Museum of Denmark, the Greenland Institute of Natural Resources, and The Greenland National Museum and Archives in Nuuk. Permits for the survey were obtained in advance from the Greenland National Museum and Archives in Nuuk. Walsh et al. (2020) provides an overview of the archaeological surveys conducted during the VIMOA project and Walsh et al. (in prep) provides further details specific to The Bear Trap and surrounding archaeological contexts. Walsh et al.
