Content TitleLot BoundariesContent TypeHosted Feature LayerDescriptionNSW Land Parcel and Property Theme MultiCRS - Lot is a polygon feature that defines a parcel of land created on a survey plan. 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 Lot is made up of the following features within the NSW Land Parcel and Property Theme.Cadastral Fabric – LotLot - 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, Integrated Titling System (ITS) title status, and stratum label.Land and property data underpins the economic, social and environmental fabric of NSW 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 planningInform water and carbon accounting programsSpatial 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.Initial Publication Date05/02/2020Data Currency01/01/3000Data Update FrequencyDailyContent SourceData provider filesFile TypeESRI File Geodatabase (*.gdb)Attribution© State of New South Wales (Spatial Services, a business unit of the Department of Customer Service NSW).

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. A program to upgrade the spatial location and accuracy of data is ongoing.Spatial Reference
