1936/1938 DEM of Svalbard

This dataset presents a 1936/1938 3D reconstruction of Svalbard from NP's archive of 5,507 aerial images acquired during the summers of 1936 and 1938 (Luncke, 1936). The dataset contains a Svalbard-wide DEM and orthophotomosaic from 1936/1938 and an elevation change map (1936 to ~2010) at 20 and 50 m resolution. Higher-resolution (5 m) DEMs and orthophotos also are available, but the data are separated into 8 regions due to file size constraints. The dataset also contains a shapefile inventory of the 1936/1938 glacier extents and an .xlsx spreadsheet with glacier-by-glacier mass balance statistics and climate parameters. See README.txt for a complete description of the files. The data are associated with the following article: Geyman, E.C., van Pelt, W., Maloof, A.C., Faste Aas, H., and Kohler, J., 2021.
