Data generated from slope corrected orthometric heights of Antarctica derived from ERS Radar Altimetry

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.
