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 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.

Refer to the documentation included with the data.
Note there is a group of pixels with positive elevation, but less than 1 metre, to the south-west of Heard Island at about 53 degrees 6'53"S 73 degrees 15'1"E.
These are likely to be artefacts in the DEM.
These data are only available for projects conducted in conjunction with the Australian Antarctic Division.
