Camden Railway 3D May 2024

Access APIMetadata Portal Metadata InformationContent Title Camden 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.

准确性：该数据集与地块和房产数字数据集保持位置关系及对齐。地块和房产数据是通过数字化最佳可用地籍图获取的，其比例尺和精度各异，根据澳大利亚国家制图委员会《地图精度标准》（1975年），范围从1:500到1:250000。因此，90%的明确定义点的特征实例位置在地图比例尺下误差不超过0.5毫米，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。目前正在进行位置升级（精度提升）计划。特征高度源自激光雷达（LiDAR）高程数据源，包括1米和2米数字高程模型（Digital Elevation Model，DEM）。用于创建DEM的数据具有0.3米（95%置信区间）的垂直精度和0.8米（95%置信区间）的水平精度。特征的垂直精度也取决于其视野范围。
