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. This dataset has been generalised from the high resolution vector polyline. Medium resolution versions of ADD data are suitable for scales smaller than 1:1,000,000, although certain regions will appear more detailed than others due to variable data availability and coastline characteristics. Changes in v7.12 include updates to the ice shelves around Alexander Island, such as Wilkins, George VI and Bach Ice Shelves; the coastline around Thwaites and Pine Island Glaciers, Bryan Coast and Abbot Ice Shelf, and changes to the coast at Vaughan Inlet. 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. Generalised Antarctic coastline south of 60°S, consisting of ice coastline, rock coastline, grounding line, ice shelf and front, ice rumple, and 'rock against ice shelf' line features.

The dataset was created using ArcGIS and QGIS GIS software programmes and has been checked for basic topography and geometry errors, but does not contain strict topology. Quality varies across the dataset, certain areas where high resolution source data were available are suitable for large scale maps, whereas other areas are only suitable for smaller scales. Each line has attributes detailing the source, which can give the user further indications of its suitability for specific uses. Attributes also give information, including `surface` (e.g. grounding line, ice coastline, ice shelf front) and revision date (`revdate`), accompanied by `revprec` - date precision, either day, month, or year. Compiled from sources ranging in time from the 1990s to 2026 - individual lines contain exact source dates in the `sourcedate` field with the corresponding `sourceprec` field. This medium resolution version has been generalised from the high resolution version. All areas <0.1km² not intersecting anything else were deleted, and the *simplify* tool was used in ArcGIS with the *retain critical points* algorithm and a smoothing tolerance of 50m. unrestricted Open Access (Anonymous) license This information is licensed under the Creative Commons Attribution-NoDerivatives 4.0 International Licence (CC BY-ND 4.0).
