Wollongong Railway 3D May 2024

Access APIMetadata Portal Metadata InformationContent Title Wollongong 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 CommonStandard 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.

精度说明：本数据集与地块与房产数字数据集保持位置关联与对齐。地块与房产数据通过数字化多比例尺、多精度的现有最佳地籍测绘数据获取，精度范围遵循澳大利亚国家测绘委员会1975年《地图精度标准》，覆盖1:500至1:250000。据此，90%的明确定义点位的位置误差在对应地图比例尺下的0.5毫米范围内：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。当前正实施位置精度提升项目。要素高度源自激光雷达（LiDAR）高程数据源，包括1米与2米分辨率的数字高程模型（DEM，Digital Elevation Model）。制作DEM所用数据的垂直精度为0.3米（95%置信区间），水平精度为0.8米（95%置信区间）。要素的垂直精度同时受其所处地平线条件影响。
