NSW Land Parcel and Property Theme – Authority Reference

Please Note
WGS 84 = GDA94 service

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 Authority Reference are made up of the following data:

· Authority Reference: depicts the changes to an area definition that has occurred through a gazettal, act or government file action.

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.

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 Spatial 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 the Department of Trade and Investment.

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.
