Australian National Topographic Base Map with Multiple Data Sources

The National Base Map service provides seamless topographic colour mapping for the whole of Australia, including outer islands and external territories. The service consists of data sourced from Geoscience Australia, Australian Antarctic Division, OpenStreetMap, and other programs like ACLUMP. The topographic information was checked in 2008 using satellite imagery and supplemented in 2009.

Use Cases

• Create regional or national maps based on the seamless topographic colour mapping.
• Analyze land use and vegetation patterns based on the aggregated ACLUMP layer.
• Study transport networks based on OpenStreetMap-derived road data.
• Model terrain relief based on SRTM-derived elevation data.
• Map coastal and marine features based on bathymetry sourced from Natural Earth.

Strengths

• Covers the whole of Australia, including outer islands and external territories.
• Integrates data from multiple authoritative sources like Geoscience Australia and OpenStreetMap.
• Includes detailed graphic representations of cultural, hydrography, marine, transport, vegetation and relief themes.

Limitations

• Limited field checking has been undertaken; some information may not be accurate.
• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
