Australian State Boundaries With GDA2020 Datum

Geoscape Australia's NT State Boundary dataset provides official digital boundaries for Australian states and territories, derived from authoritative state and territory cadastre data. The dataset is part of the broader Geoscape Administrative Boundaries collection, which includes seven themes such as ABS boundaries and local government areas. As of November 2019, data is available in both the GDA94 and newer GDA2020 geodetic datums.

Use Cases

• Mapping state-level administrative regions using the official boundary polygons for thematic mapping.
• Spatial analysis of phenomena constrained by state borders, utilizing the GDA2020 or GDA94 coordinate reference systems.
• Joining state boundary features with other datasets using the legal identifiers provided for each state and territory.
• Creating base maps for electoral or local government area analysis as part of the seven-theme Administrative Boundaries collection.

Strengths

• Data is derived from authoritative government cadastre sources from each state and territory jurisdiction.
• Offers a choice between two geodetic datums (GDA94 and GDA2020) for coordinate referencing.
• Part of a larger collection containing boundaries across seven administrative themes.

Limitations

• Specific row counts, column details, and dataset size are unknown.
• The description references a specific update from November 2019, suggesting the core data may be temporally stale for recent boundary changes.
