Australian Topographic Base Map With Integrated Land Use And Transport Data

A seamless topographic color map covering all of Australia, its external territories, and the Australian Antarctic Territory. The service integrates data from Geoscience Australia, the Australian Antarctic Division, OpenStreetMap, and the Australian Bureau of Statistics. Topographic information was checked in 2008-2009, with suburbs data from 2018 and 2020.

Use Cases

• Analyze land use patterns using the aggregated ACLUMP vegetation layer for the Australian continent.
• Map transportation networks by integrating OpenStreetMap road data with Geoscience Australia's topographic features.
• Model terrain relief using SRTM DEM data processed for stripe removal, void filling, and vegetation offset removal.
• Create coastal and marine charts by combining bathymetry from Natural Earth with hydrographic and marine themes.
• Visualize suburban boundaries and demographics by overlaying ABS Suburb 2018 and 2020 data on the base map.

Strengths

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

Limitations

• Core topographic information was validated in 2008-2009 and may not reflect recent changes.
• Limited field checking was undertaken, so some feature accuracy is not guaranteed.
• Data composition changes based on zoom scale, switching between GEODATA TOPO 250K and OpenStreetMap sources.
