The ESRI ArcGIS 3D analyst extension was used to generate this TIN using only the valid points in the shapefile. The Antarctic coastline, from the Antarctic Digital Database version 3, was used as a breakline in the TIN generation. There is a large hole in the polar region of the radar altimetry data so the TIN is unreliable in this area. This is also the case in large areas of invalid heights. Refer to metadata record ERS_REL_ANT for information about a shapefile that gives an indication of areas of invalid heights. Generally the TIN is unreliable in latitudes south of 82 degrees south and steep areas of the continent, particularly along the coast.These data are publicly available for download from the provided URL.This data set conforms to the CCBY Attribution License (http://creativecommons.org/licenses/by/4.0/).

The data is in a Polar Stereographic projection with true scale at 71 degrees South. The TIN is unreliable in latitudes south of 82 degrees South and steep areas of the continent, particularly along the coast.
ESA's two European Remote Sensing (ERS) satellites, ERS-1 and 2, were launched into the same orbit in 1991 and 1995 respectively. Their payloads included a synthetic aperture imaging radar, radar altimeter and instruments to measure ocean surface temperature and wind fields.
ERS-2 added an additional sensor for atmospheric ozone monitoring. The two satellites acquired a combined data set extending over two decades.
The ERS-1 mission ended on 10 March 2000 and ERS-2 was retired on 05 September 2011.VIEW RELATED INFORMATIONhttp://data.aad.gov.au/aadc/metadata/citation.cfm?entry_id=ERS_DTM_TIN_ANTCitation reference for this metadata record and datasetGET DATAhttps://data.aad.gov.au/eds/4723/downloadDownload the datasetERS_DTMNot providedScience AssociatedAMD/AUCEOSAMDCEOS IDN DIFVERSION 10.22003-02-112019-04-051970-01-01T00:00:001970-01-01T00:00:00Not provided
