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.
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.
