Digital Elevation Model of Vestfold Hills, Antarctica
A Digital Elevation Model (DEM) of the Vestfold Hills with cell size 10 metres was interpolated from input coastline, contour, spot height (point locations with an elevation attribute) and lake data from the dataset described by the metadata record 'Vestfold Hills 1:25000 Topographic GIS Datase...

The horizontal datum is WGS84. The vertical datum is Mean Sea Level. The DEM was initially created as a raster in an ESRI file geodatabase. The geodatabase also includes slope, aspect and hillshade rasters derived from the DEM using ArcGIS. Slope is in degrees. Azimuth 315 degrees and altitude 45 degrees were chosen for the hillshade.
