Western Australia State Border from Spatial Cadastral Database

Landgate provides the official State Border of Western Australia, separating it from South Australia and the Northern Territory along the 129 degrees East meridian. The layer is derived from the Spatial Cadastral Database and based on the GDA 2020 datum, superseding the previous LGATE-194 version.

Use Cases

• Perform spatial joins with other administrative boundary layers using the precise geometry for jurisdictional analysis.
• Integrate the border geometry into mapping services for visualizing state-level administrative divisions.
• Use the GDA 2020 datum-aligned geometry as a foundational reference layer for regional GIS projects.

Strengths

• Authoritative source from the Western Australian Land Information Authority (Landgate).
• Geodetic data is aligned to the modern GDA 2020 datum.
• Available in multiple standard geospatial formats including GeoJSON, SHP, and Geopackage.

Limitations

• No row or column count, sample data, or file size information is provided.
• The dataset's specific attributes and feature properties are unknown.
