Medium resolution vector polylines of the Antarctic coastline - VERSION 7.11
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 60degS. 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 v7.11 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.

Methodology:
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 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 2025 - 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.
