National Base Map: Greyscale Topographic Imagery for Australia and Territories

Australia and its external territories are covered by this seamless greyscale topographic mapping service. The service was produced for the National Map project, combining Geoscience Australia data at smaller scales with OpenStreetMap data at larger scales. It was last updated on 2026-04-16 09:18:50.001077.

Use Cases

• Create basemaps for thematic overlays based on the seamless topographic greyscale mapping.
• Perform spatial analysis at varying scales based on the layer scale dependencies.
• Develop web mapping applications for Australia using the WMTS service format.

Strengths

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