The data set does not in general include the grounding zone at the inland margin of the ice shelves or glaciers.\r\n\r\nThe margin was defined by interpretation of an image mosaic generated from Synthetic Aperture Radar data.  The image mosaic was built using navigation data accompanying the SAR images to transform the images to a map projection. The image navigation data were adjusted so that overlapping images were registered to one another, the indivual images merged into a mosaic, and the overall process adjusted so that the mosaic was tied to the few ground control points available in this large sector.  Two separate mosaics were used to span the whole sector.\r\n\r\nThe majority of the SAR data were acquired by the ERS-SAR instruments in August 1996, some ERS data were acquired in August 1993, and one Radarsat scene was acquired in September 1997.  The data were pre-processed to produce a mosaic with a 100 m pixel size, and adjusted so that the majority of the coastline positions refer to the August 1996 epoch.\r\n\r\nThe location data are internally consistent, and extracted at nominally 200 m intervals.  The external position accuracy is generally better than 600 m. The coverage is complete over the whole sector.  The coordinate set includes some island/ice rise features.  Two very large grounded icebergs are included.\r\n\r\nData are in an ascii arc/info export file format as geographic coordinates on the ITRF1996 system and contains attribute information.\r\n\r\nERS-SAR data, copyright ESA, 1993, 1996\r\n\r\nRadarsat data, copyright Canadian Space Agency, Agence spatiale canadienne, 1997.\r\n\r\nThis work was completed as part of ASAC projects 454, 1125 and 2224 (ASAC_454, ASAC_1125 and ASAC_2224).", "num_resources": 6, "num_tags": 12, "organization": {"id": "3e666ea1-f7c8-4382-a342-0e0bbc88ce9a", "name": "australianantarcticdivision", "title": "Australian Antarctic Division", "type": "organization", "description": "The Australian Antarctic Data Centre (AADC) was established in 1996 to provide long-term management of Australia's Antarctic data, thereby improving the value and impact of our scientific activities.

We work collaboratively with national and international centres, networks, and scientists, providing data management and analysis services as well as actively engaging in scientific research.
