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.

本数据集为南极海岸线数据，基于多种测绘与遥感数据源生成，以多边形要素形式提供，附带“陆地（land）”“冰架（ice shelf）”“冰舌（ice tongue）”与“褶皱冰（rumple）”四类属性。
数据集覆盖南纬60°以南的全部陆地与冰架区域，适用于地形测绘与相关分析工作。
ADD数据的高分辨率版本适用于比例尺大于1:1000000的制图场景，最大适用比例尺可变且取决于具体区域。
v7.6版本的更新内容包括：埃默里冰架（Amery Ice Shelf）前缘、劳穹山（Law Dome）东侧的冰架与冰川，以及阿博特冰架（Abbot Ice Shelf）与派恩岛冰川（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（Mapping and Geographic Information Centre）及英国极地数据中心（UK Polar Data Centre），代表南极研究科学委员会（Scientific Committee on Antarctic Research）负责编制、管理与分发。
