516 maps comprise the AUSTopo series, the largest-scale topographic map collection covering the entire Australian continent. Each standard map sheet covers approximately 1.5 degrees longitude by 1 degree latitude, showing natural and constructed features like roads, vegetation, hydrography, and 50-meter contours. Geoscience Australia produces these maps, which use GDA94/GDA2020 datum and UTM projection, with the last update recorded for March 2026.
Use Cases
- Terrain analysis and elevation modeling based on 50-meter contour intervals
- Infrastructure planning and routing based on road and rail network data
- Environmental and land cover studies based on vegetation and hydrography features
- Creating base maps for regional GIS projects based on standardized sheet coverage
Strengths
- Covers the entire Australian continent at a consistent 1:250,000 scale
- Comprises 516 map sheets with standardized coverage areas
- Includes approximately 50 special maps for non-standard areas like coastal regions
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Data is provided in PDF format, which may require conversion for direct geospatial analysis
