National Base Map: Greyscale Topographic Mapping for Australia

Geoscience Australia provides seamless greyscale topographic mapping for the whole of Australia and its external territories. The service combines Geoscience Australia data at smaller scales with OpenStreetMap data at larger scales. It was last updated on 2026-05-14.

Use Cases

• Create basemap visualizations for web applications based on the seamless national coverage.
• Perform geospatial analysis using integrated topographic data from multiple sources.
• Support cartographic design and planning with greyscale mapping for the whole of Australia.

Strengths

• Covers the whole of Australia, including external territories like Cocos (Keeling) Islands and Christmas Island.
• Integrates data from authoritative (Geoscience Australia) and community (OpenStreetMap) sources.
• Last updated date is provided (2026-05-14).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic or source bias inherent to the contributing platforms.
