Australian National Topographic Base Map Without Labels

A seamless topographic colour map service covering all of Australia, its external territories, and the Australian Antarctic Territory. The map integrates data from Geoscience Australia, the Australian Antarctic Division, and OpenStreetMap, with specific island data sourced from NATMAP datasets at 1:30,000 and 1:25,000 scales. The underlying SRTM elevation data was acquired by NASA in February 2000 and processed by Geoscience Australia.

Use Cases

• Creating custom thematic maps based on the detailed topographic features.
• Performing spatial analysis using the integrated cultural, hydrography, and transport themes.
• Overlaying proprietary or custom data layers onto a standardized national basemap.
• Visualizing terrain and relief using the processed SRTM-derived elevation data.

Strengths

• Covers the entire Australian continent, its external territories, and the Australian Antarctic Territory.
• Integrates data from multiple authoritative sources including Geoscience Australia and OpenStreetMap.
• Includes high-resolution (1:25,000 and 1:30,000 scale) mapping data for Christmas Island and Cocos (Keeling) Islands.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Topographic information was last checked in 2008-2009, and limited field checking was undertaken, so some information may not be accurate.
• Column-level documentation is absent; field semantics must be inferred after download.
