NSW Joint Private Works Schemes-Private Water Trusts

The mapped boundaries of Private Water Trusts within the State of NSW and the parcels within them are described. \r\n\r\nIn the first half of 2024 the boundaries of the Private Water Trusts were mapped by NSW Public Works within a single spatial (GIS) dataset using a reference NSW cadastre from February 2024 and a datum of GDA2020. \r\n\r\nThe scheme boundaries were mapped using the following methods in descending order: \r\n1.\tGeoreferencing images of gazetted maps to the NSW Cadastre and matching boundaries. \r\n2.\tFollowing gazetted boundary descriptions. This would typically require georeferencing an image of a Parish Plan that was published at a similar date to the gazettal notice to provide context to the descriptions. NSW Spatial Services Aerial Imagery was traced when descriptions or maps referred to physical boundaries like creeks, rivers, and water channels. \r\n3.\tUsing a gazetted schedule of parcels. \r\n4.\tUsing Parish Plans when Private Water Trusts were mapped on them. \r\n\r\nThe list of Private Water Trusts and the references to gazettal notices was provided by the Water Group, Department of Climate Change, Energy, the Environment and Water, NSW Government.\r\n\r\n\r\n\r\n-----------------------------------\r\n\r\nNote: If you would like to ask a question, make any suggestions, or tell us how you are using this dataset, please visit the [NSW Water Hub which has an online forum](https://water-hub.seed.nsw.gov.au/thread/search) you can join.\r\n\r\n\r\n本数据集详述了新南威尔士州（NSW）境内私人水信托（Private Water Trusts）的测绘边界及其内部所辖地块。 2024年上半年，新南威尔士州公共工程部依托2024年2月的新南威尔士州地籍参考数据与GDA2020大地基准，将私人水信托的边界整合至单个空间地理信息系统（GIS）数据集并完成测绘。 该类边界的测绘工作按以下优先级从高到低依次开展： 1. 将官方公告地图的影像地理配准至新南威尔士州地籍系统，并匹配对应边界。 2. 依据官方公布的边界描述开展测绘。此类工作通常需将与官方公告发布日期相近的教区规划影像进行配准，以为边界描述提供上下文参考；当边界描述或地图提及溪流、河流及水道等实体边界时，将参考新南威尔士州空间服务局的航空影像进行边界描绘。 3. 采用官方公布的地块清单开展测绘。 4. 若私人水信托的边界已在教区规划中标注，则直接使用该规划数据完成测绘。 私人水信托清单及官方公告引用信息由新南威尔士州政府气候变化、能源、环境与水利部水利组提供。 ----------------------------------- 注意：若您有疑问、提出建议或希望分享该数据集的使用场景，请访问[新南威尔士州水利枢纽在线论坛](https://water-hub.seed.nsw.gov.au/thread/search)并加入交流。
