Digital terrain model of Antarctica in ESRI Grid format, derived from ERS Radar Altimeter data.
Entry ID: ERS_DTM_GRID_ANT


Summary
Abstract: 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 ... View entire text

Quality 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.
