Topography of the north western Sørkapp Land (Svalbard) in the year 1961

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 „glacier_1961_northwestern_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 shapefile „contour_1961_northwestern_Sorkappland.shp” 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 „peak_1961_northwestern_Sorkappland.shp” 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).

The raster file „dem_1961_5m_northwestern_Sorkappland.tif” contains Digital Elevation Model (DEM) with 5 m resolution generated from corrected contour lines.
