Full description

Data generated from slope corrected orthometric heights derived from ERS radar altimetry as described in the paper 'A Digital Terrain Ice Model of Antarctica derived by ERS Radar Altimeter Data' by J. Ihde, J. Eck, U. Schirmer.

The data products (and their metadata records): the original point data as a shapefile (GRI_ORT_SLC_FIN); a shapefile showing data and no data areas for the original point data (ERS_REL_ANT); a triangulated irregular network (TIN) generated from the point data (ERS_DTM_TIN_ANT); 500 m interval contours interpolated from the TIN (ERS_CONT_500_ANT); a raster grid with 5 km cell size interpolated from the TIN (ERS_DTM_GRID_ANT); a contour shapefile for the Amery Region map published by the Australian Antarctic Data Centre in November 2002 - contours sourced from ERS radar altimetry, the Antarctic Digital Database Version 2 and Russian space photography (ERS_CONT_MERGED_AMERY); a shapefile used for the contour source diagram for the Amery Region map (ERS_CONT_SOURCE_AMERY).

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.
