The datasets contain vector layers (topographic and glacier outlines) and Digital Elevation Model (DEM) covering western part of Sørkapp Land peninsula, Svalbard, for the year 1961. The first shape file „glacier_1961_western_Sorkappland.shp” 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 shape file „contour_1961_western_Sorkappland.shp” contains contour lines with intervals of 10 m based on digitized historical maps edited in 1987 by Institute of Geophysics of Polish Academy of Sciences and registered using cartographic grid and elevation points. Shape file „peak_1961_western_Sorkappland.shp” contains elevation points – topographic and triangulation – used in the process of vector data registration. Shape file „rock_1961_western_Sorkappland.shp” delineates areas very steep presented on the source maps as a rock cliff symbols. This file also indicates areas where highest elevation errors in the generated Digital Elevation Model are plausible. All shape files were produced in the UTM projection system (northern hemisphere, zone 33) based on WGS84 ellipsoid (datum D_WGS_1984). The raster file „dem_1961_20m_western_Sorkappland.tif” contains Digital Elevation Model (DEM) with 20 m resolution generated from corrected contour lines.
