Drone-based glacier mapping of Nordenskiöldbreen and Tunabreen in Svalbard, 2026

This database contains drone-based mapping data of two glaciers, Svalbard, Norway. The glaciers are Tunabreen in Templefjord and Nordenskiöldbreen in Billefjord. The dataset was generated using a structure-from-motion (SfM) method using drone-based imagery. The data was processed with Agisoft Metashape and the processed data consists of digital elevation models (DEMs) in georeferenced .TIF file format, orthomosaic maps in georeferenced .TIF file format, and textured 3D models in .STL and .JPG file format. In addition, a process report in .PDF file format is included for each dataset. Mapping was conducted with a DJI Mavic 2 (2026). The mapping area covers the crevassed glacier fronts. Data collection was conducted on Nordenskiöldbreen in Summer 2026 (2026-09-07). Data collection was conducted on Tunabreen in Summer Summer 2026 (2026-09-06). The campains were conducted in collaboration with the University Centre in Svalbard (UNIS) and the field course AT-334/834 Arctic Marine Measurements Techniques, Operations and Transport.
