收藏资源简介:
Metadata Content Title NSW Basemap Light GreyContent Type Web MapDescription The NSW Basemap Light Grey theme includes minimal key data for localities, roads, hydrology, and landform with a light neutral background.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. 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 \n\n
元数据 内容标题:新南威尔士州(New South Wales,NSW)浅灰色底图 内容类型:Web地图(Web Map) 描述:本新南威尔士州浅灰色底图主题包含极简核心数据,涵盖居民地、道路、水文及地貌要素,搭配浅中性色调背景。 首次发布日期:2022年7月14日 数据现势性:2024年5月15日 数据更新频率:其他 内容来源:其他 文件类型:地图要素服务(Map Feature Service) 署名信息:无 数据主题、分类及与其他数据集的关联关系:无 精度:本数据集通过数字化多种比例尺与精度等级的最优地籍测绘数据采集而成,比例尺范围涵盖1:500至1:250000,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地图比例尺下不超过0.5mm,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。目前正开展位置精度提升项目。 数据集空间参考系:澳大利亚大地基准1994(Geocentric Datum of Australia 1994,GDA94) Web服务空间参考系:EPSG:4326 与WGS84等效:GDA94 空间范围:无 内容溯源:无 数据密级:非密 数据访问政策:开放 数据质量:无 条款与条件:知识共享(Creative Commons) 标准与规范:无 数据保管方:空间服务部 | 新南威尔士州顾客服务厅(NSW Department of Customer Service) 联系人:DCS空间服务客户中心(DCS Spatial Services Customer Hub) 数据聚合方:DCS空间服务部(DCS Spatial Services) 数据分发方:DCS空间服务部(DCS Spatial Services) 附加辅助信息:新南威尔士州底图为矢量瓦片(Vector Tile)Web可访问地图,可为用户提供更快的加载速度,并在所有缩放级别下实现高分辨率显示。矢量瓦片图层可适配特定显示设备的分辨率,还可重新样式化以适配多种使用场景。 Web服务用途与适用性:本Web地图服务可使用户轻松将新南威尔士州底图集成至空间平台与应用程序中,并提供新南威尔士州基础空间数据的组合视图。本服务符合开放地理空间联盟(Open Geospatial Consortium,OGC)标准,适配常见GIS平台调用。该Web地图会定期更新,可展示由DCS空间服务部采集或获取的最新信息。本服务所使用的所有数据集均为权威基础空间数据。 底图图例: TRIM编号:
