Windmill Islands penguin colonies digitised from 1990 Linhof aerial photography

Aerial photography (Linhof) of penguin colonies was acquired over the Windmill Islands (Eric Woehler).The penguin colonies were traced, then digitised (John Cox), and saved as DXF-files.Using the ArcView extension 'Register and Transform' (Tom Velthuis), The DXF-files were brought into a GIS and transformed to the appropriate islands. Data conforms to SCAR Feature Catalogue which can be searched (refer to link below).

采用林哈夫（Linhof）相机拍摄的企鹅群落航空影像，由埃里克·韦勒（Eric Woehler）在风车群岛（Windmill Islands）区域上空采集完成。企鹅群落的轮廓经约翰·考克斯（John Cox）勾勒描边并数字化后，保存为DXF文件。借助汤姆·韦尔特惠斯（Tom Velthuis）开发的ArcView扩展工具‘配准与转换（Register and Transform）’，上述DXF文件被导入地理信息系统（GIS），并转换至对应岛屿的地理坐标系中。本数据集符合南极研究科学委员会（SCAR）地物目录标准，可通过下方链接检索。
