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

<p>The datasets contain vector layers (topographic and glacier outlines) and Digital Elevation Model (DEM) covering the north western part of S&oslash;rkapp Land peninsula, Svalbard, for the year 1961. The first shapefile &bdquo;<em>glacier_1961_northwestern_Sorkappland.shp&rdquo;</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 &bdquo;<em>contour_1961_northwestern_Sorkappland.shp</em>&rdquo; 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 &bdquo;<em>peak_1961_northwestern_Sorkappland.shp</em>&rdquo; contains elevation points &ndash; topographic and triangulation &ndash; used in the process of vector data registration.&nbsp;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 &bdquo;<em>dem_1961_5m_northwestern_Sorkappland.tif</em>&rdquo; contains Digital Elevation Model (DEM) with 5 m resolution generated from corrected contour lines.</p>
