Metadata Content Title NSW Basemap NavigationContent Type Web MapDescription The NSW Basemap Navigation theme provides detailed road and street data symbolised with a minimal style over the NSW imagery layer.Initial Publication Date 14/07/2022Data Currency 15/05/2024Data Update Frequency Other Content Source OtherFile Type Map Feature Service Attribution Data Theme, Classification or Relationship to other Datasets Accuracy 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 of positional upgrade (accuracy improvement) is currently underway.Spatial Reference System (dataset) GDA94 Spatial Reference System (web service) EPSG:4326 WGS84 Equivalent To GDA94 Spatial Extent Content Lineage Data Classification UnclassifiedData Access Policy OpenData Quality Terms and Conditions Creative CommonsStandard and Specification Data Custodian Spatial Services | NSW Department of Customer ServicePoint of Contact DCS Spatial Services Customer HubData Aggregator DCS Spatial ServicesData Distributor DCS Spatial ServicesAdditional Supporting Information NSW Basemaps are vector tile, web accessible maps that enable faster\nloading times for users and high-resolution display at all zoom levels. Vector\ntile layers can adapt to the resolution of a particular display device and can\nbe restyled for multiple uses. The NSW Basemap Navigation theme provides\ndetailed road and street data symbolised with a custom minimal style over the\nNSW imagery layer. Web service uses/ fitness for purpose:This web map service allows users to easily integrate the NSW Basemap into spatial platforms and applications and provides a combined view of NSW Foundation Spatial Data. It is Open Geospatial Consortium (OGC) compliant and suitable for consumption by common GIS platforms. The web map is regularly updated and will show new information captured or sourced by DCS Spatial Services. All datasets used in this service are authoritative foundational spatial data.Basemap legendTRIM Number

精度说明:本数据集通过数字化多种比例尺与精度的现有最佳地籍测绘数据制作而成,比例尺范围覆盖1:500至1:250 000,符合澳大利亚国家测绘委员会1975年发布的《地图精度标准》。据此,90%的明确特征点的位置误差在对应比例尺下的0.5毫米范围内。具体换算如下: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。
