BA SYD selected GA TOPO 250K data plus added map features
收藏资源简介：
## **Abstract** \n\nThis dataset is derived from GA TOPO 250K Series 3 features clipped to the BA_SYD and environs extent for the purpose of providing geographic context in BA_SYD report map images. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.\n\n\n\nSelected features currently include:\n\nLakes\n\nPlaceNames\\*\n\nPopulatedPlaces\n\nRailways\n\nRoads\n\nWatercourseLines\n\n\n\nadditional features may be included as required (relevant feature classes asterisked). \n\n\n\nCurrently the only addition has been to PlaceNames with the addition of Census Spring (see Lineage).\n\n## **Purpose** \n\nproviding geographic context in BA_SYD report map images.\n\n## **Dataset History** \n\nA rectangular mask polygon feature was manually drawn around the BA_SYD (ie NSB+SSB) boundary extending approximately 100km beyond the BA_SYD extent. This mask is included in the dataset (SYD_clip).\n\n\n\nSelected features from the national GEODATA TOPO 250K series 3 were overlaid with the mask and intersecting features extracted.\n\n\n\nExtracted feature classes have the same names as the source features.\n\n\n\nThe additional feature of "Census Spring" was added to place names. It's approximate location was sourced from \n\nFig 4, p172 of the document :\n\n\n\nDuralie Coal (2013) Duralie Coal Mine - Water Management Plan (Document No. WAMP-R02-D) Appendix 3 - Groundwater Management Plan .

## **摘要** 本数据集源自GA TOPO 250K系列3（GA TOPO 250K Series 3）要素，经裁剪至BA_SYD及其周边范围，用于为BA_SYD报告的地图图像提供地理背景支撑。本元数据声明的"谱系"字段已注明源数据集信息，制作该衍生数据集的具体流程详见本元数据声明的"历史"字段。 目前已选取的要素包括： 湖泊（Lakes） 地名（PlaceNames*） 居民地（PopulatedPlaces） 铁路（Railways） 道路（Roads） 水系线（WatercourseLines） 可根据需求添加其他要素（带星号的为相关要素类）。 目前仅针对地名要素类添加了"普查泉（Census Spring）"（详见谱系字段）。 ## **用途** 为BA_SYD报告的地图图像提供地理背景支撑。 ## **数据集历史** 围绕BA_SYD（即NSB+SSB）边界手动绘制了一个矩形掩膜面要素，其范围超出BA_SYD边界约100公里。该掩膜已包含在本数据集（SYD_clip）中。 从国家GEODATA TOPO 250K系列3中选取的要素与该掩膜叠加，并提取相交要素。 提取的要素类与源要素名称保持一致。 此外，针对地名要素类添加了"普查泉（Census Spring）"，其近似位置源自该文档图4，第172页： Duralie Coal（2013）《杜拉利煤矿水资源管理计划》（文件编号：WAMP-R02-D）附录3——地下水管理计划，2013年9月，文件编号：GWMP-R02-C（00519574），图4，第13页。 文档链接：http://www.gloucestercoal.com.au/documents/community_environment/duralie/Duralie_Coal_Mine_Water_Management_Plan.pdf ## **数据集引用** 生物区域评估项目（2014）《BA_SYD选取的GA TOPO 250K数据及新增地图要素》，生物区域评估衍生数据集，2019年3月13日查阅，http://data.bioregionalassessments.gov.au/dataset/ba5feac2-b35a-4611-82da-5b6213777069。 ## **数据集溯源** * **衍生自** [GEODATA TOPO 250K系列3（GEODATA TOPO 250K Series 3）](https://data.gov.au/data/dataset/a0650f18-518a-4b99-a553-44f82f28bb5f)
