A seamless topographic greyscale mapping service for the whole of Australia and its external territories. 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 2026-04-18.

Use Cases

• Visualize topographic features across Australia based on the seamless greyscale mapping service.
• Integrate multi-scale map data for regional analysis based on the combination of Geoscience Australia and OpenStreetMap sources.
• Develop base layers for thematic web maps based on the service produced for the National Map project.

Strengths

• Covers the entire landmass of Australia and its external territories, including Cocos (Keeling) Islands, Christmas Island, Norfolk Island, and Lord Howe Island.
• Combines authoritative data from Geoscience Australia with crowd-sourced data from OpenStreetMap for multi-scale representation.

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.
