High resolution vector polylines of the Antarctic coastline - VERSION 7.7

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. 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 v7.7 include updates Brunt Ice Shelf, ice fronts on the east side of the Antarctic Peninsula, Pine Island and Thwaites Glaciers and the ice fronts and coastline around Charcot Island. Data quality checks were also performed to ensure existing features were categorised correctly around Getz 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.

本数据集为依托多类测绘与遥感数据源制作的南极海岸线数据集，涵盖以下海岸类型：冰海岸线（ice coastline）、岩质海岸线（rock coastline）、接地线（grounding line）、冰架及其前缘（ice shelf and front）、冰皱丘（ice rumple），以及与冰架毗邻的岩岸（rock against ice shelf）。数据集覆盖南纬60°以南的全部陆地与冰架，可用于地形测绘与相关分析工作。其ADD数据的高分辨率版本适用于比例尺大于1:100万的制图作业，且最大适用比例尺可因区域差异有所调整。7.7版本的更新内容包括：布伦特冰架（Brunt Ice Shelf）、南极半岛（Antarctic Peninsula）东侧的冰架前缘、派恩岛冰川（Pine Island Glacier）与斯韦茨冰川（Thwaites Glacier），以及夏科岛（Charcot Island）周边的冰架前缘与海岸线的修订。本次更新还针对盖茨冰架（Getz Ice Shelf）周边区域开展了数据质量核查，以确保现有地貌要素的分类准确无误。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）进行编制、管理与分发。
