Rason SH51-03: 1:250,000 Scale Digital Topographic Map of Australia

516 maps cover the entire Australian continent at a scale of 1:250,000, the largest scale for full coverage. Each standard map sheet covers an area of approximately 1.5 degrees longitude by 1 degree latitude, showing natural and constructed features. Geoscience Australia Data produced this series, which 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 GIS applications based on standardized sheet lines and coordinate systems.

Strengths

• Covers the entire Australian continent with 516 map sheets.
• Standard map sheets cover a consistent area of ~1.5° longitude by 1° latitude.
• 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 in PDF format, which may require conversion for direct geospatial analysis.
