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）曾使用的麦夸里岛（Macquarie Island）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。直至2001年6月通用横轴墨卡托（Universal Transverse Mercator, UTM）网格系统被启用前，该系统始终被用于数据记录工作。 本元数据记录可下载的数据集包含标注有该网格系统的地图，以及一份由杰夫·科普森（Geoff Copson）编制的文档，其中详细记载了公园与野生动物服务局网格系统至UTM网格系统的转换方法。杰夫在文档中指出：“1971年发布的地图在该岛中部两个区块内的精度偏差尤为显著。公园与野生动物服务局的网格系统为手工绘制，精度波动较大。转换参数以全岛沿岸各点位的测量值取平均得到。”
