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 ContactSS-SDS@customerservice.nsw.gov.auData 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:本数据集与宗地与房产数字数据集保持位置关联与对齐。宗地与房产数据通过数字化各类比例尺与精度的现有地籍测绘成果采集,依据澳大利亚国家测绘委员会1975年《地图精度标准》,比例尺范围覆盖1:500至1:250000。据此,90%的明确特征点在对应地图比例尺下的位置误差不超过0.5毫米:即1:500比例尺对应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。当前正开展位置精度提升项目。特征点高程源自激光雷达(LiDAR)高程数据源,包括1米与2米分辨率的数字高程模型(DEM)。用于生成DEM的数据垂直精度为95%置信区间内0.3米,水平精度为95%置信区间内0.8米。特征点的垂直精度同时受其所在视野范围影响。
