AUSTopo's 1:250,000 scale digital map series covers the entire continent of Australia across 516 standard sheets. Each standard sheet covers an area of approximately 1.5 degrees longitude by 1 degree latitude, showing natural and constructed features including roads, rail, vegetation, hydrography, and 50-meter contours. The data is provided by Geoscience Australia in PDF format with coordinates in GDA94/GDA2020 datum and UTM projection.
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 GIS projects based on standardized sheet coverage.
Strengths
- Covers the entire continent of Australia at its largest published topographic scale.
- Series comprises 516 standard map sheets with consistent coverage area.
- Includes multiple feature types such as infrastructure, vegetation, hydrography, and contours.
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.
- Row count is unknown, which may limit suitability assessment.
