资源简介:
This database contains drone-based mapping data of the crevassed and surging glacier of Borebreen in Svalbard, Norway. The dataset was generated using a structure-from-motion (SfM) method using drone-based imagery. The data was processed with Agisoft Metashape (version 1.8.5) and the processed data consists of digital elevation models (DEMs) in georeferenced .TIF file format, orthomosaic maps in georeferenced .TIF, and textured 3D models in .STL and .PDF file format. In addition, a process report in archived .PDF file format is included for each dataset. Mapping was conducted with a DJI Mavic 2 Pro Enterprise. The fieldwork was conducted in August of 2023 over several days with access to Borebreen via boat. The mapping area covers the crevassed glacier front on five days between 01 Aug 2023 and 12 Aug 2023. In addition, the glacier forefield was mapped over several days and combined into one fileset. There are two subsets of data. First, there are the files Glacier-subset-A/B for the 20230811 dataset. This data contains a subset of the glacier which was taken before (A) anda after (B) a major calving event happening on the same day. It is intended to study very short time-span calving rates. The second dataset is the Forefield-subset, that includes a larger area that was mapped using oblique mapping (in constrast to the nadir mapping in the rest of the dataset. Processing of the data was conducted by Richard Hann. Data aquisiton by Richard Hann and Nil Rodes (20230801). Project and fieldwork support by Wojciech Gajek, Danni Pearce, and William Harcourt.
