National Base Map: Greyscale Topographic Tiles for Australia

A seamless greyscale topographic mapping service for the whole of Australia, including 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 2026-05-14.

Use Cases

• Create thematic overlays based on the seamless greyscale topographic base.
• Provide cartographic context for national-scale mapping projects based on the whole-of-Australia coverage.
• Develop web mapping applications using the WMTS service format mentioned in the description.

Strengths

• Covers the whole of Australia, including external territories like Cocos (Keeling) Islands and Christmas Island.
• Integrates data from two authoritative sources: Geoscience Australia and OpenStreetMap.

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.
