Coastline for Antarctica created from various mapping and remote sensing sources, consisting of the following coast types: 'ice coastline', 'rock coastline', 'grounding line', 'ice shelf and front', 'ice rumple', and 'rock against ice shelf', provided as a surface attribute. Covering all land and ice shelves south of 60°S. Suitable for topographic mapping and analysis. High resolution versions of ADD data are suitable for scales larger than 1:1,000,000. The largest suitable scale is changeable and dependent on the region.

Changes in v7.11 include updates to the coastline of Adelaide Island and surrounding islands, the grounding line of Alexander Island and the surrounding region, and the ice shelf front of the Brunt Ice Shelf. In addition, sourcedate and revdate attributes were updated to a consistent YYYY-MM-DD format. To indicate limited date precision for earlier records, sourceprec and revprec attributes were introduced.

Data compiled, managed and distributed by the Mapping and Geographic Information Centre and the UK Polar Data Centre, British Antarctic Survey on behalf of the Scientific Committee on Antarctic Research.
