Australia and its external territories of Cocos (Keeling) Islands, Christmas Island, Norfolk Island, and Lord Howe Island are covered by this seamless greyscale topographic mapping service. The service is produced for the National Map project, combining Geoscience Australia data at smaller scales with OpenStreetMap data at larger scales. It was last updated on 2026-04-10 and is provided by the Australian Ocean Data Network.
Use Cases
- Create basemaps for web applications based on the seamless topographic greyscale mapping.
- Perform spatial analysis for Australia and its external territories based on the geographic coverage.
- Integrate multi-scale topographic data based on the layer scale dependencies and combined Geoscience Australia/OpenStreetMap sources.
Strengths
- Covers the whole of Australia and four external territories.
- Combines authoritative Geoscience Australia data with community-sourced OpenStreetMap data.
- Provides seamless mapping with layer scale dependencies for multi-scale use.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic/source bias inherent to the contributing datasets.
