NSW Land Parcel Property Theme multiCRS

Export DataAccess APINSW Land Parcel and Property Theme multiCRSMultiCRS service - supporting requests in multiple Coordinate Reference Systems -Information SheetA new series of ‘multiCRS’ web services have been published to support GDA2020.  These new ‘multiCRS’ services:·have a spatial reference of GDA2020·support alignment with GDA2020, GDA94 or [WGS 84-aligned-to-GDA2020] GIS environments,using built-in server-side transformations:oGDA94 < NTv2-CPD > GDA2020oGDA94 < NTv2-CPD > WGS 84 aligned to GDA94oGDA2020 < NULL > WGS 84 aligned to GDA94     Note: ESRI software will automatically align by transforming from the sourceSpatialReference (GDA94).               Other software may need to set client-side transformations from the SpatialReference (GDA2020).     Note: Client-side transformation(s) can be used to over-ride these default transformations.The original [WGS 84-aligned-to-GDA94] is still available, without the ‘multiCRS’ suffix. In due course, and allowing time for user feedback and testing, it is intended that the original service name will adopt this new 'multiCRS' functionality.Metadata Portal Metadata InformationContent TitleNSW Land Parcel Property Theme MultiCRSContent TypeHosted Feature LayerDescriptionNSW Land Parcel Property Theme MultiCRS is a polygon dataset that represents areas of land with defined boundaries, under unique ownership for specific property rights or interests. This service supports requests in multiple coordinate reference systems.A land parcel is an area of land with defined boundaries, under unique ownership for specific property rights or interests.A property is something that is capable of being owned, in the form of real property (land). The interest can involve physical aspects, such as the use of land, or conceptual rights, such as a right to use the land in the future.The NSW cadastre is an up-to-date parcel-based land information system which contains a unique identifier which can be linked of interests in land (i.e. rights, restrictions and responsibilities). The cadastre includes a geometric definition of land parcels linked to other records, such as land titles, describing the nature of the interests, the ownership or control of those interests, and often the value of the parcel and its improvements.A cadastral product or service visualises the boundaries of land parcels, often buildings on land, the parcel identifier, and basic topographic features.The land parcel and property theme provide the foundation fabric of land ownership.  It consists of the digital cadastral database and associated parcel and property information.Datasets that make up the Land Parcel and Property Theme include:Cadastral Fabric Lot - depicts a parcel of land created on a survey plan. Each lot may be represented by standard lots, standard part lots, strata or stratum. Each lot has a lot number, section number, plan lot area, plan number, plan label, ITS title status, and stratum label.Road - represents dedicated public roads which are open ways for the passage of vehicles, persons or animals on land. The road dataset includes public roads in use. Each road type has a section number, plan number, plan label, ITS title status, road type, road width or Crown/Council width, lot number, and stratum label.Unidentified - represents a parcel of land that cannot be identified. Crown land, vested, dedicated and severed land may be included in this category as well as Old System lots for which lot/DP identification cannot be found. This dataset also identifies the locations of 100ft wide reserves, ACT regions, closed roads, crossings, surveyed areas, and un-surveyed areas.Water feature - represents tidal, non-tidal and ocean waters which form a cadastral boundary.Cadastral Features Easement (including Carriageway) - depicts a right, attached to land (the dominant tenement), to use other land (the servient tenement) for a specified non-exclusive purpose known to the law, e.g. right of carriageway, easement to drain water etc. – however the law also recognises an easement in favour of a statutory authority without a dominant tenement, described as an ‘easement in gross’.Road Corridor - represents the spatial extent of the legal road networkRoad Centreline - represents a line that forms the centreline of cadastral road corridors.Railway Corridor - represents a part of the Land Parcel and Property Theme covering railway land that is not defined by a lot.Water feature Corridor - represents the extent of a water feature or the delineation between water features of a different type or status. The dataset contains high water mark, low water mark, the limit of tidal influence and bay closing lines.Watermark - represents the spatial extent of tidal, non-tidal and ocean waters which form a cadastral boundary.Authority Reference: depicts the changes to an area definition that has occurred through a gazettal, act or government file action.Property - Property data is a polygon feature class that spatially represents an aspatial property description as provided by Property NSW in their Valnet database.Properties are divided into three categories:Property (complete)IncompleteOtherLand and property data underpins the economic, social and fabric environment of Australia and is used, amongst other things, to:secure tenure for access to capitaldefine allowable use of landmanage native title, nature conservation, heritage protection, defence, and disaster managementimprove infrastructure and property development planningwater and carbon accounting programs.The Spatial Services digital cadastral data maintenance program captures all changes to the statewide cadastral fabric from new survey plans and a variety of other sources.The cadastral data upgrade program is improving the spatial accuracy of the cadastral fabric by using survey dimensions and improved survey control. Upgrades are carried out together with the relevant Local Government Authority and are further facilitated through the incorporation of data provided by Local Government Authorities, Hunter Water and Sydney Water.Upgrade positional accuracy varies across the state and generally ranges from less than 5m from true position in rural areas to less than 0.2m from true position in urban areas, dependent on the survey control available.Data quality in both Cadastral Maintenance and Cadastral Upgrade is assured through specification compliance and datatopology rules.Spatial Services is currently undertaking a cadastral supply chain digital transformation initiative thorough the Cadastre NSW Program.Spatial Services continuously updates this theme with information sourced from relevant stakeholders and custodians. Most updates to the datasets in this theme originate from subdivision, registration and gazettal activity.Spatial Services works with Local and State Government to upgrade the accuracy of Spatial Services Defined Administrative Data Sets.Initial Publication Date05/02/2020Data Currency01/01/3000Data Update FrequencyDailyContent SourceData provider files

导出DataAccess API新南威尔士州（NSW）土地地块与产权主题多CRS（multiCRS）服务——支持多坐标参考系统请求——信息表

新一批多CRS（multiCRS）网络服务已发布，以支持GDA2020。这些全新的多CRS服务具备以下特性：
· 空间参考为GDA2020
· 支持与GDA2020、GDA94或[与GDA2020对齐的WGS 84]地理信息系统（Geographic Information System, GIS）环境适配，通过内置的服务器端坐标转换实现：
o GDA94 < NTv2-CPD > GDA2020
o GDA94 < NTv2-CPD > 与GDA94对齐的WGS 84
o GDA2020 < NULL > 与GDA94对齐的WGS 84

注意：ESRI软件将自动通过源空间参考（GDA94）进行转换以完成对齐。其他软件则可能需要从空间参考（GDA2020）设置客户端坐标转换。
注意：客户端坐标转换可用于覆盖上述默认转换规则。

原[与GDA94对齐的WGS 84]服务仍可使用，无需添加"multiCRS"后缀。在收集用户反馈与开展测试的过渡期后，计划将原服务名称升级为该全新的多CRS功能版本。

内容类型：托管要素图层（Hosted Feature Layer）
描述：NSW土地地块与产权主题多CRS服务是一类多边形数据集，用于表征具备明确边界、归属于唯一所有者且对应特定产权或权益的土地范围。本服务支持多坐标参考系统请求。

土地地块指具备明确边界、归属于唯一所有者且对应特定产权或权益的土地范围。
产权指可被所有的对象，以不动产（土地）形式存在。该权益可涉及实体层面（如土地使用）或概念性权利（如未来土地使用权）。

新南威尔士州地籍系统是一套基于最新地块的土地信息系统，包含唯一标识符，可关联土地相关权益（即权利、限制与责任）。地籍系统包含与各类记录关联的土地地块几何定义，例如土地权属证书，用于描述权益性质、该权益的所有权或管控情况，通常还包含地块价值及其改良情况。

地籍产品或服务可可视化展示土地地块边界、地块上的建构筑物、地块标识符及基础地形要素。

土地地块与产权主题构成了土地权属的基础架构，由数字地籍数据库及关联的地块与产权信息组成。

构成土地地块与产权主题的数据集包括：
1. 地籍架构宗地（Cadastral Fabric Lot）：描绘基于勘测规划生成的土地地块。每宗地可通过标准宗地、标准部分宗地、分层地块表示。每宗地包含宗地号、区域编号、规划地块面积、规划编号、规划标签、ITS权属状态及分层标签。
2. 道路（Road）：表征专门用于车辆、人员或牲畜通行的公共专用道路。本道路数据集包含在用公共道路。每条道路包含区域编号、规划编号、规划标签、ITS权属状态、道路类型、道路宽度或王室/市政宽度、宗地号及分层标签。
3. 未识别地块（Unidentified）：表征无法识别的土地地块。王室土地、已授予、已专用及已分割土地均可归入此类，同时包含无法找到宗地/备案计划编号的旧系统宗地。本数据集还标注了100英尺宽储备地、ACT区域、封闭道路、道口、勘测区域及未勘测区域的位置。
4. 水体要素（Water feature）：表征构成地籍边界的潮汐水域、非潮汐水域及海洋水域。
5. 地籍要素 地役权（含行车道）（Cadastral Features Easement (including Carriageway)）：描绘附属于某宗土地（需役地）的权利，用于为特定法律认可的非排他性目的使用其他土地（供役地），例如行车道权、排水地役权等——不过法律也认可无需需役地的法定权利人地役权，即"总地役权"。
6. 道路廊道（Road Corridor）：表征合法道路网络的空间范围。
7. 道路中心线（Road Centreline）：表征构成地籍道路廊道中心线的线状要素。
8. 铁路廊道（Railway Corridor）：表征土地地块与产权主题中未通过宗地定义的铁路用地范围。
9. 水体要素廊道（Water feature Corridor）：表征水体要素的范围，或不同类型/状态水体要素之间的分界线。本数据集包含高水位线、低水位线、潮汐影响范围边界及海湾闭合线。
10. 水域范围（Watermark）：表征构成地籍边界的潮汐水域、非潮汐水域及海洋水域的空间范围。
11. 权限参考（Authority Reference）：描绘通过公告、法案或政府文件操作产生的区域定义变更。
12. 产权（Property）：产权数据是一类多边形要素类，用于在空间上表示新南威尔士州产权厅（Property NSW）在其Valnet数据库中提供的非空间产权描述。
产权分为三类：
- 完整产权（Property (complete)）
- 未完成产权（Incomplete）
- 其他产权（Other）

土地与产权数据是澳大利亚经济、社会与环境架构的基础，其应用场景包括但不限于：
- 保障获取资本的权属
- 界定土地的合法使用用途
- 管理原生土地权、自然保护、遗产保护、国防及灾害管理
- 优化基础设施与物业开发规划
- 开展水资源与碳核算项目。

空间服务局（Spatial Services）的数字地籍数据维护项目会从新勘测规划及其他各类来源捕获全州范围内地籍架构的所有变更。
地籍数据升级项目通过使用勘测尺寸与优化的勘测控制基准，提升地籍架构的空间精度。升级工作由相关地方政府当局协同开展，并通过整合地方政府当局、亨特水务（Hunter Water）及悉尼水务（Sydney Water）提供的数据进一步推进。
全州范围内的升级位置精度存在差异，通常在农村地区与真实位置的偏差小于5米，在城市地区则小于0.2米，具体取决于可用的勘测控制基准。
地籍维护与地籍升级的数据质量均通过规范合规性与数据拓扑规则进行保障。

空间服务局目前正通过新南威尔士州地籍计划（Cadastre NSW Program）推进地籍供应链数字化转型项目。
空间服务局持续从相关利益相关方与托管方获取信息，以更新本主题数据集。本主题数据集的大多数更新源自地块细分、权属登记及公告活动。
空间服务局与地方及州政府合作，提升空间服务局定义的管理数据集的精度。
