A spatial reference system for coastal ice-free land in East Antarctica

This dataset comprises a table and set of maps of all geographic sites of ice-free land along the East Antarctica coastline between longitudes 37°E and 160°E. Each geographic site comprises a discrete area of ice-free land and includes islands within 100 km of the coast and outcrops of ice free continental rock within 1 km of the coast. The geographic sites were identified in a geographic information system using polygons sourced from the AAT Coastline 2003 dataset produced by Geoscience Australia and the Australian Antarctic Division, and exposed rock polygons sourced from the Antarctic Digital Database version 4.0 produced for the Scientific Committee on Antarctic Research. The maps are grouped into sub-regions and regions, with multiple maps in most sub-regions. The maps were designed to be of a scale that could be used in the field to identify sites by their shape and location. This dataset has previously been used in the specific context of potential breeding habitat for Adelie penguins (doi:10.4225/15/5758F4EC91665) but has potential for broader use in a wide range of ecological and environmental studies.

本数据集包含东经37°至160°沿线南极东海岸线所有无冰陆地地理点位的表格与地图集。每一处地理点位均对应一片独立的无冰陆地区域，涵盖海岸100公里范围内的岛屿，以及海岸1公里范围内的裸露大陆岩石露头。
上述地理点位通过地理信息系统（Geographic Information System）识别获取，所用多边形要素分别源自澳大利亚地质调查局（Geoscience Australia）与澳大利亚南极司（Australian Antarctic Division）制作的《AAT海岸线2003》（AAT Coastline 2003）数据集，以及南极研究科学委员会（Scientific Committee on Antarctic Research）编制的《南极数字数据库4.0版》（Antarctic Digital Database version 4.0）中的裸露岩石多边形数据。
该图集按子区域与大区进行分组，多数子区域包含多幅地图，其比例尺设计适配野外作业场景，可通过形状与位置快速识别目标点位。本数据集此前曾被应用于阿德利企鹅潜在繁殖栖息地的专项研究（doi:10.4225/15/5758F4EC91665），同时具备在各类生态与环境研究中拓展应用的潜力。
