New South Wales Cadastral Land Parcel Boundaries

Lot polygons define parcels of land created on survey plans, visualizing boundaries, parcel identifiers, and basic topographic features. This dataset provides the foundation fabric of land ownership in NSW, consisting of the digital cadastral database and associated parcel and property information. It is maintained by Spatial Services (DCS) and was last updated in April 2026.

Use Cases

• Analyze plan lot area and lot number for property valuation and development feasibility studies.
• Map stratum labels and ITS title status to manage strata or stratum property ownership records.
• Use parcel boundary lines with recorded dimensions for cadastral survey validation and dispute resolution.
• Filter by section number and plan label for historical land use research and heritage conservation planning.
• Integrate lot polygons with topographic features for disaster management and flood risk modeling.

Strengths

• Provides the foundational digital cadastral database for the state of New South Wales.
• Includes attributes for lot number, plan number, plan lot area, and title status per parcel.
• Offers both a REST API and data export options for access.

Limitations

• The specific GDA94 service is scheduled for retirement, requiring users to transition to a new GDA2020 service.
• The spatial reference (GDA94) cannot be easily consumed into GDA2020 environments.
• Row count, column details, and precise temporal coverage are unknown.
