Contour source data for the Amery Region map dated November 2002.

This polygon shapefile was used in the contour source diagram on the Amery Region Map published by the Australian Antarctic Data Centre in November 2002 (see link).The contours used in the map were derived from a number of different data sources:1 - Russian Space Photography, ERS-1 Radar Altimeter data and digitised from 1:1 million scale maps produced by National Mapping Australia;2 - Antarctic Digital Database Version 2;3 - ERS-1 and ERS-2 Radar Altimeter data (BKG, Germany).This shapefile shows in which part of the map each source was used.本多边形形状文件（shapefile）曾用于2002年11月由澳大利亚南极数据中心（Australian Antarctic Data Centre）发布的埃默里地区地图的等值线源图中（详见链接）。该地图所使用的等值线源自多个不同数据源：1. 俄罗斯航天摄影数据、ERS-1雷达高度计数据，以及源自澳大利亚国家测绘局（National Mapping Australia）制作的1:100万比例尺地图的数字化成果；2. 南极数字数据库（Antarctic Digital Database）第2版；3. 德国BKG的ERS-1与ERS-2雷达高度计数据。本形状文件标注了各数据源在地图中的具体应用区域。
