Drone-based glacier mapping of Borebreen in Svalbard, 2024
<p>This database contains drone-based glacier mapping data of Borebreen, Svalbard, Norway. The glacier is located in Isfjorden. 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 3 Pro Enterprise. The mapping area covers the crevassed glacier fronts. Data collection was conducted over three days in August/September 2024. The three collection dates were 2024-08-14, 2024-08-28, and 2024-09-25. </p>

<p>The datasets contain vector layers (topographic and glacier outlines) and Digital Elevation Model (DEM) covering the north western part of Sørkapp Land peninsula, Svalbard, for the year 1961. The first shapefile „<em>glacier_1961_northwestern_Sorkappland.shp”</em> contains the glacier areas manually delineated from vertical aerial photos captured during the historical photogrammetric overflight commissioned by the Norwegian Polar Institute on August 24 and 25, 1961. The shapefile „<em>contour_1961_northwestern_Sorkappland.shp</em>” contains contour lines with intervals of 10 m based on digitized historical maps edited in 1987 by the Institute of Geophysics of the Polish Academy of Sciences and registered using cartographic grid and elevation points. Shapefile „<em>peak_1961_northwestern_Sorkappland.shp</em>” contains elevation points – topographic and triangulation – used in the process of vector data registration. All shapefiles were produced in the UTM projection system (northern hemisphere, zone 33) based on ETRS89 ellipsoid (datum D_ETRS_1989).</p> <p>The raster file „<em>dem_1961_5m_northwestern_Sorkappland.tif</em>” contains Digital Elevation Model (DEM) with 5 m resolution generated from corrected contour lines.</p>
