Aerial photography (Linhof) of penguin colonies was acquired over the Vestfold Hills (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.

本次采集的企鹅群落航空摄影数据由埃里克·韦勒（Eric Woehler）使用林哈夫（Linhof）相机，在韦斯特福尔丘陵（Vestfold Hills）上空完成拍摄。随后由约翰·考克斯（John Cox）对企鹅群落轮廓进行勾勒并完成数字化处理，最终保存为DXF格式文件。之后由汤姆·维尔特休伊斯（Tom Velthuis）使用ArcView的扩展模块"配准与变换（Register and Transform）"，将上述DXF文件导入地理信息系统（GIS），并校正匹配至对应的岛屿范围。
