Bathurst Railway 3D May 2024

Access APIMetadata Portal Metadata InformationContent TitleBathurst Railway 3D May 2024Content TypeScene Layer/Scene Layer PackageDescriptionNSW Transport Theme Railway represents a permanent way of having one or more rail lines which provide tracks for vehicles. A railway can be heavy rails, light rail, monorail and heavy rail siding, for example a railway, tramway or monorail.Initial Publication Date01/05/2024Data Currency01/05/2024Data Update FrequencyOtherContent SourceData provider filesFile TypeScene Layer Package (*.slpk)AttributionData Theme, Classification or Relationship to other DatasetsTransport Theme of the NSW Foundation Spatial Data FrameworkAccuracyThe dataset maintains a positional relationship to, and alignment with, the Lot and Property digital datasets. The Lot and Property data 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 the 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 1:00000 = 50m. A program of positional upgrade (accuracy improvement) is currently underway. Feature heights have been derived from LiDAR elevation sources including 1m and 2m DEMS. The data used to create the DEMs have an accuracy of 0.3m (95% Confidence Interval) vertical and 0.8m (95% Confidence Interval) horizontal. The features vertical accuracy is also a function of its horizon.Spatial Reference System (dataset)WGS84Spatial Reference System (web service)EPSG:4326WGS84 Equivalent ToGDA2020Spatial ExtentContent LineageData ClassificationUnclassifiedData Access PolicyOpenData QualityTerms and ConditionsCreative CommonsStandard and SpecificationData CustodianSpatial Services | Department of Customer ServicesPoint of [e-mail] AggregatorSpatial Services | Department of Customer ServicesData DistributorSpatial Services | Department of Customer ServicesAdditional Supporting InformationOpen Geospatial Consortium (OGC) implemented and compatible for the consumption by common GIS platforms.

精度：本数据集与地块及房产数字数据集（Lot and Property digital datasets）保持位置关联及对齐。地块及房产数据通过对地籍测绘（cadastral mapping）成果数字化获取，所采用的地籍测绘成果为不同比例尺及精度的最佳可用数据，比例尺范围从1:500至1:250000，符合澳大利亚国家测绘委员会《地图精度标准》（1975年）。因此，对于90%的明确定义点，要素实例的位置在地图比例尺下误差不超过0.5毫米。即1:500比例尺对应0.25米误差，1:2000对应1米误差，1:4000对应2米误差，1:25000对应12.5米误差，1:50000对应25米误差，1:100000对应50米误差。目前正在开展位置精度升级（准确性提升）项目。要素高度源自激光雷达（LiDAR）高程数据源，包括1米及2米分辨率的数字高程模型（Digital Elevation Models，DEMs）。用于创建数字高程模型的数据具有0.3米（95%置信区间，Confidence Interval）的垂直精度及0.8米（95%置信区间）的水平精度。要素的垂直精度亦与其水平范围相关。
