A grid system used by the Parks and Wildlife Service, Tasmania, for Macquarie Island, 1974 to June 2001

This metadata record describes a grid system for Macquarie Island formerly used by the Parks and Wildlife Service, Tasmania.The grid was first adopted by Irynej Skira in 1974 and was based on the 1:50000 scale map of the island published by Australia's Division of National Mapping in 1971. Data was continually recorded on this system up to June 2001 when the Universal Transverse Mercator (UTM) grid was adopted. The dataset available for download from this metadata record includes a map with the grid system and a document compiled by Geoff Copson with details about converting from the Parks and Wildlife grid to the UTM grid. Geoff states in the document "The 1971 map was particularly inaccurate in the centre two quarters of the island. The grid for the Parks and Wildlife Service system was hand drawn and fairly variable. Conversion values are averaged out on coastal points around the island."

本元数据记录描述了塔斯马尼亚州公园与野生动物服务局（Parks and Wildlife Service, Tasmania）此前用于麦夸里岛（Macquarie Island）的网格系统。该网格系统于1974年由伊雷内·斯基拉（Irynej Skira）首次采用，其基准为澳大利亚国家测绘局（Australia's Division of National Mapping）1971年发布的该岛1:50000比例尺地图。依托该系统的数据采集工作持续至2001年6月，此后通用横轴墨卡托（Universal Transverse Mercator, UTM）网格被正式启用。
本元数据记录可下载的数据集包含该网格系统地图，以及由杰夫·科普森（Geoff Copson）编制的转换文档，其中详细记载了从公园与野生动物服务局网格系统转换至UTM网格系统的方法。杰夫在文档中指出："1971年发布的地图在该岛中部的两个区域误差尤为显著。公园与野生动物服务局的网格系统为手绘完成，精度存在一定波动。本次转换参数均以环岛沿海点位的平均值计算得出。"
