NSW Land Parcel Property Theme multiCRS

 Access 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:o    GDA94 < NTv2-CPD > GDA2020o    GDA94 < NTv2-CPD > WGS 84 aligned to GDA94o    GDA2020 < 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 functionally.NSW Land Parcel Property Theme is a polygon dataset that represents areas of land with defined boundaries, under unique ownership for specific property rights or interests.

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 provides 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 Carrigeway): 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 network

·     Road 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)·     Incomplete·     Other

Land and property data underpins the economic, social and fabric environmental of Australia and is used, amongst other things, to:

·     secure tenure for access to capital·     define allowable use of land·     manage native title, nature conservation, heritage protection, defence, and disaster management·     improve infrastructure and property development planning·     water 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. The majority of 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.

Relationship to Themes and Datasets  

NSW Land Parcel Property Theme of the Foundation Spatial Data Framework (FSDF)  

Accuracy 

The dataset maintains a positional relationship to, and alignment with, the Lot and Property digital datasets. 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 of positional upgrade (accuracy improvement) is currently underway.
