Title: A Digital Elevation Model of Heard Island derived from TerraSAR satellite imagery
Description:
Abstract:
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.

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.
