NSW Administrative Boundaries Theme - Federal Electoral Division

Access APIAdministrative Boundaries Theme -\nFederal Electoral DivisionPlease 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 ‘multiCRS’\nsuffix is available which can support GDA2020, GDA94 and WGS 84 ≈ GDA2020\nenvironments.\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 - Federal Electoral DivisionContent TypeHosted Feature LayerDescriptionNSW Federal Electoral Division is a feature class which represents a gazetted area of a federal electoral division that has been defined by redistribution.NSW Federal Electoral Division is a feature class within the administrative boundaries theme. It represents a gazetted area of a federal electoral division that has been defined by redistribution. Australian Electoral Commission is responsible for this dataset. Any changes that occur to the dataset should have a reference in the authority of reference feature class in the administrative boundaries.Features are typically positioned in alignment within the extents of the cadastral polygons and NSW Lot and Property data changes impact this dataset. This dataset is current as per last redistribution.Initial Publication Date05/02/2020Data Currency01/01/3000Data Update FrequencyOtherContent SourceData provider filesFile TypeESRI File Geodatabase (*.gdb)Attribution© State of New South Wales (Spatial Services, a business unit of the Department of Customer Service NSW). For current information go to spatial.nsw.gov.auData Theme, Classification or Relationship to other DatasetsNSW Administrative Boundaries Theme of the Foundation Spatial Data Framework (FSDF)AccuracyThe dataset maintains a positional relationship to, and alignment with, the Lot and Property digital datasets. This dataset was captured by digitising the best available cadastral mapping at a variety of scales and accuracies, ranging from 1:500 to 1:250 000 according to the National Mapping Council of Australia, Standards of Map Accuracy (1975). Therefore, the position of the feature instance will be within 0.5mm at map scale for 90% of the well-defined points. That is, 1:500 = 0.25m, 1:2000 = 1m, 1:4000 = 2m, 1:25000 = 12.5m, 1:50000 = 25m and 1:100000 = 50m. A program to upgrade the spatial location and accuracy of data is ongoing.Spatial Reference System (dataset)GDA94Spatial Reference System (web service)EPSG:4326WGS84 Equivalent ToGDA94Spatial ExtentFull StateContent LineageFor additional information, please contact us via the Spatial Services Customer HubData ClassificationUnclassifiedData Access PolicyOpenData QualityFor additional information, please contact us via the Spatial Services Customer HubTerms and ConditionsCreative CommonsStandard and SpecificationOpen Geospatial Consortium (OGC) implemented and compatible for consumption by common GIS platforms. Available as either cache or non-cache, depending on client use or requirement.Information about the Feature Class and Domain Name descriptions for the NSW Administrative Boundaries Theme can be found in the NSW Cadastral Data Dictionary.Some of Spatial Services Datasets are designed to work together for example NSW Address Point and NSW Address String (table), NSW Property (Polygon) and NSW Property Lot (table) and NSW Lot (polygons). To do this you need to add a Spatial Join.A Spatial Join is a GIS operation that affixes data from one feature layer’s attribute table to another from a spatial perspective.To see how NSW Address, Property, Lot Geometry data and tables can be spatially joined, download the Data Model Document. Data CustodianDCS Spatial Services346 Panorama AveBathurst NSW 2795Point of ContactPlease contact us via the Spatial Services Customer HubData AggregatorDCS Spatial Services346 Panorama AveBathurst NSW 2795Data DistributorDCS Spatial Services346 Panorama AveBathurst NSW 2795Additional Supporting InformationData DictionariesData Model Document. TRIM Number

访问API行政边界主题 - 联邦选举区
请注意
本服务基于世界大地测量系统1984（WGS 84）构建，已对齐至澳大利亚大地测量基准1994（GDA94）。
本数据集的空间参考为「WGS 84 ≈ GDA94」，在澳大利亚大地测量基准2020（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。
后续将预留用户反馈与测试周期，计划为原服务新增multiCRS功能。

内容标题：新南威尔士州行政边界主题 - 联邦选举区
内容类型：托管要素图层（Hosted Feature Layer）
描述：新南威尔士州联邦选举区是一个要素类，代表经官方公告划定的联邦选举区范围，该范围由选区重划程序确定。本要素类隶属于行政边界主题，其对应区域均为经澳大利亚选举委员会（Australian Electoral Commission）公告划定的选区范围。数据集的任何变更均需参考行政边界主题中的权威要素类进行溯源。
要素通常与地籍多边形范围保持对齐，新南威尔士州地块与房产数据的变更会对本数据集产生影响。本数据集的最新版本基于最近一次选区重划结果。
