High resolution vector polygons of the Antarctic coastline - VERSION 7.6

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 60S. 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 v7.6 include updates to the Amery Ice Shelf front, ice shelves and glaciers east of Law Dome, and sections of coast and ice shelf around Abbot Ice Shelf and Pine Island Glacier. 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.

本数据集为南极洲海岸线数据，依托多种测绘与遥感数据源制作，以多边形矢量格式提供，属性字段包含「陆地（land）」「冰架（ice shelf）」「冰舌（ice tongue）」与「褶皱冰（rumple）」。数据集覆盖南纬60°以南的全部陆地与冰架，适用于地形测绘与相关分析工作。
南极数字数据库（Antarctic Digital Database，简称ADD）的高分辨率版本适用于比例尺大于1:1,000,000的制图场景，其最大适用比例尺并非固定，会因区域差异而有所变动。
7.6版本的更新内容包括：埃默里冰架（Amery Ice Shelf）前缘、劳穹（Law Dome）东侧的冰架与冰川，以及阿博特冰架（Abbot Ice Shelf）与松岛冰川（Pine Island Glacier）周边的海岸与冰架区段。
本数据集由英国南极调查局（British Antarctic Survey）下属的测绘与地理信息中心与英国极地数据中心（UK Polar Data Centre），代表南极研究科学委员会（Scientific Committee on Antarctic Research）完成数据的编制、管理与分发工作。
