Summary

Abstract:
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). |

Quality
| Satellite radar altimetry was used to derive the geometry of the surface of the Antarctic continent. The method is particularly effective over ocean, shelf and flat inland ice. Data from ERS-1 and ERS-2 radar altimeters was processed to produce heights with accuracies of a few centimetres over the ocean areas and 1 - 2 decimetres for the flat ice sheets of Antarctica. Distances between sample points varies from 5km near the pole to 10 km at the northern extremes. The derivation process is described in a paper titled &A Digital Terrain Ice Model of Antarctica derived by ERS Radar Altimeter Data& by J. Ihde, J. Eck, U. Schirmer. |
