A Digital Elevation Model of Heard Island derived from TerraSAR satellite imagery

This dataset is a Digital Elevation Model (DEM) of Heard Island derived from TerraSAR_X imagery using radargrammetric methods. At least one pair of ascending images and one pair of descending images were used at each location. The TerraSAR_X stereo pairs were acquired between 31 October 2009 and 14...

Description
Summary:This dataset is a Digital Elevation Model (DEM) of Heard Island derived from TerraSAR_X imagery using radargrammetric methods. At least one pair of ascending images and one pair of descending images were used at each location. The TerraSAR_X stereo pairs were acquired between 31 October 2009 and 14 November 2009. The DEM was created by a contractor for the Australian Antarctic Data Centre. It is in geotiff format stored in a UTM zone 43 projection, horizontal datum WGS84. The cell size is 10 metres. Included with the DEM are some auxiliary files and documentation. This includes: 1 an xml file with metadata; 2 a shapefile detailing the images used for each part of the DEM; 3 a geotiff showing the correlation between the images used at each point in the DEM; 4 a spreadsheet with an accuracy assessment of the DEM using ground control points provided by the Australian Antarctic Data Centre.
