NSW Water Theme - Hydro Area

Export Data Access APINSW Water Theme – Hydro AreaPlease NoteWGS 84 service aligned to GDA94This\n dataset has spatial reference [WGS 84 ≈ GDA94] which may result in \nmisalignments when viewed in GDA2020 environments. A similar service \nwith a ‘multiCRS’ suffix is available which can support GDA2020, GDA94 \nand WGS 84 ≈ GDA2020 environments.In due course, and allowing time \nfor user feedback and testing, it is intended that the original service \nname will adopt the new 'multiCRS' functionality.Metadata Portal Metadata InformationContent TitleNSW Water Theme - Hydro AreaContent TypeHosted Feature LayerDescriptionNSW Hydro Area is a polygon feature class defining hydrographic feature types. This feature class is divided into waterbody area and water course. Features within a Hydro Area class include:Waterbody - is a standard body of inland water of which flow is minor. Waterbody may be natural waterbody or man-made waterbody.Watercourse - is a way or course through which water may pass.Hydro Area feature class is also classified as perennial, non- perennial or mainly dry.Water security is one of Australia’s major challenges.Key users of the hydrology data are NSW State and Local Government agencies as well as Federal Government agencies. These bodies use this data to better manage State and Local Government assets. This hydrology data provides the NSW component of the Australian Hydrological Geospatial Fabric which is a critical input to the Australian Water Resources Information System.More widespread use of the hydrology data is also found in emergency management response and recovery efforts, hazard mitigation or disaster risk reduction, climate change, natural resource assessment, environmental planning and monitoring, insurance, mining and agriculture.Spatial Services continuously updates this theme with information sourced from relevant stakeholders and custodians; by data verification from other internal and external databases; research and through Spatial Services’ regular cycle of updating from aerial imagery and elevation data.Initial Publication Date06/02/2020Data Currency01/01/3000Data Update FrequencyOtherContent SourceData provider filesFile TypeESRI File Geodatabase (*.gdb)Attribution©\n State of New South Wales (Spatial Services, a business unit of the \nDepartment of Customer Service NSW).

Therefore, the position of the feature instance will \nbe within 0.5mm at map scale for 90% of the well-defined points.

导出数据访问API 新南威尔士州水主题——水文区域
请注意：本服务采用世界大地测量系统1984（WGS 84）并对齐至澳大利亚大地测量基准1994（GDA94）。本数据集的空间参考为[WGS 84 ≈ GDA94]，在澳大利亚大地测量基准2020（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以及WGS 84 ≈ GDA2020环境。后续将在收集用户反馈并完成测试验证后，为原服务新增"multiCRS"功能。

内容标题：新南威尔士州水主题——水文区域
内容类型：托管要素图层（Hosted Feature Layer）
描述：新南威尔士州水文区域是用于定义水文要素类型的多边形要素类。该要素类分为水体区域与水道两类。水文区域类别的要素包括：
- 水体（Waterbody）：指水流平缓的标准内陆水体，可分为天然水体与人工水体两类。
- 水道（Watercourse）：指水体流经的通道。
此外，水文区域要素类还可按常年有水、间歇有水或基本干涸进行分类。
水资源安全是澳大利亚面临的重大挑战之一。
该水文数据的核心用户为新南威尔士州、地方政府机构以及联邦政府部门，此类主体依托本数据优化州级与地方政府资产管理。本水文数据构成了澳大利亚水文地理框架中新南威尔士州部分的数据内容，而该框架是澳大利亚水资源信息系统的关键输入数据源。
该水文数据还广泛应用于应急管理响应与恢复工作、灾害减缓、灾害风险降低、气候变化应对、自然资源评估、环境规划与监测、保险、矿业与农业等领域。
空间服务部门会持续更新本主题数据，数据来源包括相关利益方与管理方提供的信息、通过内部与外部数据库开展的数据核验、相关研究，以及空间服务部门基于航空影像与高程数据开展的常规更新工作。

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》中规定的多比例尺与精度等级进行采集，比例尺范围为1:500至1:250000。因此，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，即：1:500比例尺对应0.25米、1:2000比例尺对应1米、1:4000比例尺对应2米、1:25000比例尺对应12.5米、1:50000比例尺对应25米、1:100000比例尺对应50米。目前，针对数据空间位置与精度的升级工作正在推进中。
