This dataset has a spatial reference of [WGS 84 = GDA94] and can NOT be easily consumed into GDA2020 environments. A similar service with a ‘multiCRS’ suffix is available which can support GDA2020, GDA94 and WGS84 = GDA2020 environments. In due course, and allowing time for user feedback and testing, it is intended that these original services will adopt the new multiCRS functionally.

NSW Land Parcel and Property Theme Unidentified is a polygon feature that represents a parcel of land that is unidentified. Parcel polygons are defined by a series of boundary lines that store recorded dimensions as attributes in the lines table. It visualises these boundaries of land parcels, often buildings on land, the parcel identifier, and basic topographic features.

NSW 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.

NSW Land Parcel and Property Theme Unidentified is made up of the following features within the NSW Land Parcel and Property Theme.

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.

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

· Manage native title, nature conservation, heritage, protection, defence, and disaster management

Spatial Services continuously updates the Land Parcel and Property 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.

The data is up to date to within 10 working days from when a plan is lodged at NSW Land Registry Services. Data is also sourced from Crown Lands, the Office of Environment and Heritage, the Aboriginal Land Council, Local Land Services, the Electoral Commission and NSW Trade and Investment.

The Cadastral upgrade program commenced in 2007 and is ongoing, improving the spatial accuracy of different feature classes. Upgrades are carried out in consultation with the relevant Local Government Authority and are further facilitated through the incorporation of data provided by external agencies. 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 for both Cadastral Maintenance and Cadastral Upgrade activities are assured through specification compliance and data topology rules. The client delivery database is automatically updated each evening with the changes that occurred that day in the maintenance environment.

Relationship to Themes and Datasets	Land Parcel and 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.
