NSW Administrative Boundaries Theme – 2021 Gazetted Redistributed State Electoral District

Export DataAccess APINSW Administrative Boundaries Theme – 2021 Gazetted Redistributed State Electoral DistrictPlease Note\nWGS 84 service aligned to GDA94\nThis dataset has spatial reference [WGS 84 ≈ GDA94] which may result in\nmisalignments when viewed in GDA2020 environments. A similar service with a\n‘multiCRS’ suffix is available which can support GDA2020, GDA94 and WGS 84 ≈\nGDA2020 environments.\nIn due course, and allowing time for user feedback and testing, it is intended\nthat the original service name will adopt the new multiCRS functionality.Metadata Portal Metadata InformationContent TitleNSW Administrative Boundaries Theme – 2021 Gazetted Redistributed State Electoral DistrictContent TypeHosted Feature LayerDescriptionNSW 2021 Gazetted Redistribution State Electoral District is a dataset that shows the official NSW electoral boundaries which were formalised in the 2020/21 NSW electoral redistribution and will be enacted in the NSW state election scheduled in 2023. The Electoral District boundary aligns to, or is relevant to, the cadastral line data or topographic data features which form, by definition, the boundaries between adjoining electorates.Spatial Services maintain this dataset relative to the NSW Digital Cadastral Dataset. That is, if cadastral boundaries are upgraded to better align to property boundaries shown on original survey plans (at the time of the 2020/21 electoral redistribution), State Electoral Districts are also moved to reflect this improved spatial accuracy.Initial Publication Date01/01/2020Data Currency01/01/3000Data Update FrequencyOtherContent SourceData provider filesFile TypeESRI File Geodatabase (*.gdb)Attribution© State\n of New South Wales (Spatial Services, a business unit of the Department\n of Customer Service NSW).

Therefore, the position of the feature instance will \nbe within 0.5mm at map scale for 90% of the well-defined points. That \nis, 1:500 = 0.25m, 1:2000 = 1m, 1:4000 = 2m, 1:25000 = 12.5m, 1:50000 = \n25m and 1:100000 = 50m.

请注意
WGS 84服务适配GDA94
本数据集的空间参考为[WGS 84 ≈ GDA94]，在GDA2020环境中查看时可能出现对齐偏差。另有带"multiCRS"后缀的同类服务，可支持GDA2020、GDA94及WGS 84 ≈ GDA2020环境。
后续将在收集用户反馈并完成测试后，为原服务新增multiCRS功能。

描述
新南威尔士州2021年正式公布重划的州选区数据集，展示了2020/2021年度新南威尔士州选区重划工作中敲定的官方选举边界，将在2023年新南威尔士州州级选举中正式启用。选区边界与构成相邻选举区间边界的地籍线数据或地形数据要素对齐或相关联。
本数据集由新南威尔士州空间服务部门（NSW Spatial Services）基于新南威尔士州数字地籍数据集进行维护。即若地籍边界因需与原始勘测图中的物业边界（2020/2021年度选区重划时）对齐而升级，州选区边界也将同步调整以体现空间精度的提升。

精度说明
本数据集采用澳大利亚国家测绘委员会1975年《地图精度标准》中规定的多种比例尺及精度范围进行采集，比例尺覆盖1:500至1:250000。因此，90%的明确定位点的要素实例位置误差在对应比例尺下的0.5mm范围内，即：1:500对应0.25米，1:2000对应1米，1:4000对应2米，1:25000对应12.5米，1:50000对应25米，1:100000对应50米。目前仍有一项持续进行的项目，用于升级数据的空间位置与精度。

有关NSW行政边界专题的要素类及域名描述，可查阅《新南威尔士州地籍数据字典》。
部分空间服务部门的数据集可协同使用，例如新南威尔士州地址点与新南威尔士州地址字符串（表）、新南威尔士州物业（面要素）与新南威尔士州物业地块（表）以及新南威尔士州地块（面要素）。如需实现协同，需执行空间连接操作。
空间连接是一种GIS操作，可将一个要素图层属性表中的数据从空间维度关联至另一要素图层。
