AUSTopo provides 516 digital topographic maps covering the entire continent of Australia at a 1:250,000 scale. 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. The data is produced by Geoscience Australia and was last updated in 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 regional base maps for other data overlays based on standardized sheet coverage.
Strengths
- Covers the entire Australian continent with 516 map sheets.
- Provides the largest scale (1:250,000) topographic coverage for the entire continent.
- Includes multiple coordinate datums (GDA94, GDA2020) and projections (UTM).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Data is provided as PDF files, which may limit direct machine-readability for analysis.
