Full description

ESRI formatted raster grid of the Antarctic continental terrain, derived from ERS radar altimeter data.
The data is in a Polar Stereographic projection with true scale at 71 degrees South.
The grid has 'no data' cells 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.

Progress Code: completed
Statement: This grid was interpolated from a triangulated irregular network that was generated from slope corrected orthometric heights of Antarctica (refer to metadata record ERS_DTM_TIN_ANT). The grid cells are 5000 x 5000 metres in size and there are 1081 columns and 964 rows. The ArcGIS Spatial Analyst extension was used to derive the grid from the triangulated irregular network file . Areas of invalid height in the reliability data set (refer to metadata record ERS_REL_ANT) were used to mask out (assign no data values) to corresponding cells in the grid.
