AUSTopo's 1:250,000 scale digital map series covers the entire continent of Australia with 516 standard and 50 special map sheets. Each standard sheet covers an area of approximately 1.5 degrees longitude by 1 degree latitude, showing natural and constructed features like roads, vegetation, hydrography, and 50m 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-use studies based on vegetation and hydrography features.
- Geographic reference and boundary checking based on administrative boundaries and localities.
Strengths
- Covers the entire Australian continent at its largest published topographic scale.
- Comprises 516 map sheets, providing systematic coverage.
- Includes multiple coordinate datums (GDA94, GDA2020) and a standard UTM projection.
Limitations
- Data is provided in PDF format, which may require conversion for geospatial analysis.
- Column-level documentation and sample data are unavailable, requiring manual inspection after download.
- The description notes map sheets may contain information from surrounding sheets, which could affect boundary precision.
