Medium resolution vector polygons of the Antarctic coastline - VERSION 7.11

Coastline for Antarctica created from various mapping and remote sensing sources, provided as polygons with surface values for 'land', 'ice shelf', 'ice tongue', or 'rumple'. 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 polygons. 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.
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.
