Access APINSW Base Map Web Service GDA2020GDA2020 Cached Map Tile service - See GDA2020\nWeb Services Information Sheet and GDA2020\nRaster FAQ This Cached Map Tile service is published with a spatial reference\nof WGS 84-aligned-to-GDA2020). For users who require a [WGS\n84-aligned-to-GDA94] service the original NSW Base Map Web Serviceis still available.Disclaimer: This Cached Map Tile service is created directly from the GDA94\nCached Map Tile service by simply shifting pixels by a distance equivalent to\nthe GDA94 > NTv2-CPD > GDA2020 transformation. This shift must be a whole\nnumber of pixels. As a result, where raster tiles are provided at\nlow-resolution, the display location may differ from true GDA2020 location. For\nexample, a tile at ‘zoom level 18’, with 60 cm pixel resolution, may appear\noffset from GDA2020 by ~30cm.Metadata Portal Metadata InformationContent TitleNSW Base MapContent TypeBasemapDescriptionThe NSW Base Map web service depicts a map of NSW using layers from the Digital Topographic Database, the Geocoded Urban and Rural Addressing System database and the Digital Cadastral Database.This includes:roadspoints of interestlocalitieslandformdrainagecultural dataparks and forestsproperty boundariesstreet address numbers.Web service uses/fitness for purpose This web service allows users to easily integrate a NSW base map into Open Geospatial Consortium (OGC) compliant spatial platforms and applications. This web service provides an ideal base map depicting a combined view of NSW Foundation Spatial Information for use within spatial applications and systems. Current State This web service is current and complete. Update frequency As required. Future development This web service is updated when new information has been captured or sourced by DFSI Spatial Services. Standards and specifications OGC compliant and suitable for consumption by common GIS platforms. This dataset is compliant with the NSW Foundation Spatial Data Framework and its specifications.Information Sheet (FSDS)Initial Publication Date31/07/2019Data Currency01/01/3000Data Update FrequencyOtherContent SourceOtherFile TypeMap Feature ServiceAttribution© State of New South Wales (Spatial Services, a business unit of the Department of Customer Service NSW). For current information go to spatial.nsw.gov.auData Theme, Classification or Relationship to other DatasetsThe NSW Base Map is made up from elements from NSW Administrative Boundaries, Land Parcel Property, Water, Transport and Geocoded Address Themes as well as Features of Interest and Physiography Categories of the Foundation Spatial Data Framework (FSDF) Boundaries.AccuracyThe dataset maintains a positional relationship to, and alignment with, a range of themes from the NSW FSDF including, transport, imagery, positioning, water and land cover. 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 to upgrade the spatial location and accuracy of data is ongoing.Spatial Reference System (dataset)GDA94Spatial Reference System (web service)EPSG:3857WGS84 Equivalent ToGDA2020Spatial ExtentFull StateContent LineageFor additional information, please contact us via the Spatial Services Customer HubData ClassificationUnclassifiedData Access PolicyOpenData QualityFor additional information, please contact us via the Spatial Services Customer HubTerms and ConditionsCreative CommonsStandard and SpecificationOpen Geospatial Consortium (OGC) implemented and compatible for consumption by common GIS platforms.

访问APINSW基础地图Web服务(APINSW Base Map Web Service)GDA2020(澳大利亚大地基准2020,Geocentric Datum of Australia 2020)缓存地图瓦片服务——详见《GDA2020 Web服务信息表》(GDA2020 Web Services Information Sheet)及《GDA2020栅格常见问题》(GDA2020 Raster FAQ)。本缓存地图瓦片服务采用与WGS 84对齐的GDA2020空间参考系发布。若用户需要采用WGS 84对齐GDA94(澳大利亚大地基准1994,Geocentric Datum of Australia 1994)的服务,原始NSW基础地图Web服务仍可使用。 免责声明:本缓存地图瓦片服务直接由GDA94缓存地图瓦片服务生成,仅通过像素偏移实现等效于GDA94 > NTv2-CPD > GDA2020的坐标转换,且偏移量必须为整像素数。因此,当提供低分辨率栅格瓦片时,其显示位置可能与真实GDA2020坐标存在偏差。例如,缩放级别18、像素分辨率为60厘米的瓦片,其显示位置可能偏离GDA2020坐标约30厘米。 元数据门户元数据信息 内容标题:新南威尔士州(NSW)基础地图(NSW Base Map) 内容类型:底图(Basemap) 内容描述:NSW基础地图Web服务依托数字地形数据库、地理编码城乡寻址系统数据库及数字地籍数据库的图层,绘制新南威尔士州地图。包含以下要素:道路、兴趣点、居民区、地貌、水系、人文数据、公园与林区、宗地边界、街道门牌号。 Web服务用途与适用场景:本Web服务可使用户轻松将NSW基础地图集成至符合开放地理空间联盟(Open Geospatial Consortium, OGC)标准的空间平台与应用中,为空间应用与系统提供融合了NSW基础空间信息的理想底图。 当前状态:本Web服务处于完整可用状态。 更新频率:按需更新。 未来发展规划:当DFS空间服务部(DFS Spatial Services)获取到新数据后,将对本Web服务进行更新。 标准与规范:符合OGC标准,可兼容通用地理信息系统(Geographic Information System, GIS)平台调用。本数据集符合NSW基础空间数据框架(NSW Foundation Spatial Data Framework, FSDF)及其规范要求。 信息表(FSDS) 首次发布日期:2019年7月31日 数据现势性:3000年1月1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) 署名声明:© 新南威尔士州政府(新南威尔士州客户服务部下属业务单元空间服务部)。最新信息请访问spatial.nsw.gov.au 数据主题、分类及与其他数据集的关联:NSW基础地图由NSW行政边界、宗地产权、水系、交通、地理编码地址主题,以及基础空间数据框架(FSDF)的兴趣点与地貌类别要素组合而成。 精度:本数据集与NSW FSDF的多个主题(包括交通、影像、定位、水系与土地覆盖)保持空间位置关联与对齐。本数据集依据澳大利亚国家测绘委员会1975年《地图精度标准》,通过数字化多种比例尺(1:500至1:250000)的现有最佳地籍测绘成果采集。因此,90%的明确要素点在对应比例尺地图上的位置误差不超过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。当前正在实施一项数据空间位置与精度升级计划。 空间参考系(数据集):GDA94 空间参考系(Web服务):EPSG:3857 等效基准:GDA2020 空间范围:全州范围 数据谱系:如需更多信息,请通过空间服务客户中心(Spatial Services Customer Hub)联系我们。 数据分类:非机密 数据访问政策:开放访问 数据质量:如需更多信息,请通过空间服务客户中心联系我们。 条款与条件:知识共享(Creative Commons)标准 标准与规范:符合开放地理空间联盟(OGC)标准,兼容通用GIS平台调用。可根据客户使用需求,以缓存或非缓存模式提供服务。 数据保管方:DCS空间服务部(DCS Spatial Services) 地址:澳大利亚新南威尔士州巴瑟斯特市Panorama大道346号,邮编2795 联络方式:请通过空间服务客户中心联系我们。 数据聚合方:DCS空间服务部,地址同上 数据分发方:DCS空间服务部,地址同上 附加支持信息:数据字典、信息表(FSDS)、TRIM编号
