Export Data Access APINSW Water ThemePlease NoteWGS 84 service aligned to GDA94This dataset has spatial reference [WGS 84 ≈ GDA94] which may result in misalignments when viewed in GDA2020 environments. A similar service with a ‘multiCRS’ suffix is available which can support GDA2020, GDA94 and WGS 84 ≈ GDA2020 environments.In due course, and allowing time for user feedback and testing, it is intended that the original service name will adopt the new 'multiCRS' functionality.Metadata Portal Metadata InformationContent TitleNSW Water ThemeContent TypeHosted Feature LayerDescriptionThe Water theme is based on hydrology which is the study of the movement, distribution and quality of water. This includes the hydrologic cycles, water resources and environmental watershed sustainability.Hydrology includes surface hydrology, hydrogeology, drainage basin management and water quality where water plays the central role.Water (surface water and groundwater) is concerned with information as aligned with the definitions under the Water Act 2007.This theme includes Hydrology elements which are described as:Surface Water - water in a watercourse, lake or wetland or any water flowing over or lying on land, either after having precipitated naturally after rain or having risen to the surface naturally from underground.Groundwater - water occurring at a place below ground that has been pumped, diverted or released to that place for the purpose of being stored there. Does not include water held in underground tanks, pipes or other works.Data in Water theme includesAncillary Hydro PointBoreLockRapidsSpringTidal Limit MarkerWaterfallDissipation pointRegulatorRiver GaugeBarriersSinkCoastlineMean High Water MarkMean Low Water MarkFuzzy Extent Water AreaBay-likeRiver-like AreaSea-likeFuzzy Extent Water LineRiver-likeHydro AreaWatercourse: Natural Waterbody, Canal-DrainWater body Area: Man-made Waterbody, Natural WaterbodyHydro LineNatural Watercourse AreaCanal DrainSpillwayRaceTunnel-SiphenConnectorHydro PointNatural Made WaterbodyMan Made WaterbodyNamed Water CourseNamed Water CourseWater security is one of Australia’s major challenges.

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 ToGDA94Spatial 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.

导出数据访问API:新南威尔士州(NSW)水主题数据集 请注意:适配GDA94(GDA94)的WGS 84(WGS 84)服务。本数据集的空间参考为[WGS 84 ≈ GDA94],在GDA2020环境中查看时可能出现坐标偏移。另有带“multiCRS”后缀的同类服务,可支持GDA2020、GDA94及WGS 84 ≈ GDA2020环境。待收集用户反馈并完成测试后,原服务将升级支持该多CRS功能。 元数据门户元数据信息 内容标题:新南威尔士州水主题数据集 内容类型:托管要素图层(Hosted Feature Layer) 数据集描述: 本水主题数据集基于水文学(hydrology)构建,水文学是研究水体运动、分布与水质的学科,涵盖水文循环、水资源与流域环境可持续性。水文学包含地表水文学、水文地质学、流域管理与以水为核心的水质研究范畴。本数据集的水体(地表水与地下水)信息符合《2007年水法》(Water Act 2007)中的定义。 本主题包含如下水文要素: - 地表水:指水道、湖泊或湿地中的水体,或自然降雨后径流或自然出露地表的地下水。 - 地下水:指地下储存并经抽取、导流或释放至该区域储存的水体,不包括地下储槽、管道或其他构筑物内留存的水体。 水主题数据集包含以下数据内容: 辅助水文测点(Ancillary Hydro Point)、水文钻孔(Bore)、船闸(Lock)、急滩(Rapids)、泉眼(Spring)、潮界标志(Tidal Limit Marker)、瀑布(Waterfall)、消力点(Dissipation point)、节制闸(Regulator)、水位站(River Gauge)、拦挡设施(Barriers)、汇水点(Sink)、海岸线(Coastline)、平均高潮线(Mean High Water Mark)、平均低潮线(Mean Low Water Mark)、模糊水域范围(Fuzzy Extent Water Area)、海湾型区域(Bay-like Area)、河道型区域(River-like Area)、海域型区域(Sea-like Area)、模糊水线范围(Fuzzy Extent Water Line)、河道型(River-like)、水文区域(Hydro Area)、水道:天然水体、渠沟(Watercourse: Natural Waterbody, Canal-Drain)、水体区域:人工水体、天然水体(Water body Area: Man-made Waterbody, Natural Waterbody)、水文线(Hydro Line)、天然水道区域(Natural Watercourse Area)、渠排水沟(Canal Drain)、溢洪道(Spillway)、引水渠(Race)、隧道-虹吸管(Tunnel-Siphen)、连接设施(Connector)、水文测点(Hydro Point)、天然水体(Natural Waterbody)、人工水体(Man Made Waterbody)、命名水道(Named Water Course)、命名水道(Named Water Course)。 水资源安全是澳大利亚面临的重大挑战之一。采用这套全国统一的数据产品,可助力开展数据分析、优化业务实践并辅助政策制定。 首次发布日期:2020年4月22日 数据时效性:3000年1月1日 数据更新频率:其他 数据来源:数据提供方文件 文件格式:ESRI文件地理数据库(*.gdb) 署名声明:© 新南威尔士州政府(空间服务部,新南威尔士州顾客服务部下属业务单元)。最新信息请访问 spatial.nsw.gov.au。 数据主题、分类或与其他数据集的关联:基础空间数据框架(Foundation Spatial Data Framework, FSDF)下的新南威尔士州水主题数据集。 精度说明:本数据集采用澳大利亚国家测绘委员会1975年《地图精度标准》中规定的多比例尺精度源数据制作,比例尺覆盖1:500至1:250000。据此,90%的明确点位的坐标误差在对应比例尺下的0.5mm图面误差范围内,即1:500比例尺对应实地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。当前正持续推进数据集空间位置与精度的升级工作。 数据集空间参考系统:GDA94(GDA94) Web服务空间参考系统:EPSG:3857,等效于GDA94(GDA94)的WGS 84(WGS 84) 空间覆盖范围:全州范围 数据溯源:如需更多信息,请通过空间服务客户中心联系我们。 数据分类:非保密 数据访问政策:开放获取 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:知识共享协议(Creative Commons) 标准与规范:遵循开放地理空间联盟(Open Geospatial Consortium, OGC)标准,可兼容主流GIS平台读取。根据客户端需求,可提供缓存或非缓存服务。 数据保管方:新南威尔士州顾客服务部空间服务部,地址:346 Panorama Avenue, Bathurst NSW 2795 联系人:如需联系,请通过空间服务客户中心办理。 数据聚合方:新南威尔士州顾客服务部空间服务部,地址:346 Panorama Avenue, Bathurst NSW 2795 数据分发方:新南威尔士州顾客服务部空间服务部,地址:346 Panorama Avenue, Bathurst NSW 2795 附加支持信息:数据字典:TRIM编号(TRIM Number)
