Abstract:
Coastline for Antarctica created from various mapping and remote sensing sources, provided as polygons with "land", "ice shelf", "ice tongue" or "rumple" attribute. Covering all land and ice shelves south of 60 degS. 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 v7.9 include updates to the South Orkney Islands, sections of the Filchner, West, Wilkins and George VI ice shelves, and ice fronts in eastern Dronning Maud Land and west of Law Dome.
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.

| Parent Dataset: | N/A |
| Lineage: | Dataset compiled from a variety of Antarctic map and satellite image sources. The dataset was created using ArcGIS and QGIS GIS software programmes and has been checked for basic topography and geometry checks, but does not contain strict topology. Quality varies across the dataset and 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 polygon contains a 'surface' attribute with either 'land', 'ice shelf', 'ice tongue' or 'rumple'. Details of when and how each line was created can be found in the attributes of the high resolution polyline coastline dataset. Data sources range in time from 1990s-2024 - individual lines contain exact source dates. | |
