Sir Samuel SG51-13: AUSTopo 1:250,000 Scale Digital Topographic Map of Australia

516 maps cover the entire continent of Australia at a 1:250,000 scale, the largest scale for full continental coverage. Geoscience Australia Data produced this series, which includes natural and constructed features like roads, vegetation, hydrography, and 50-meter contours. The map may contain information from surrounding sheets to maximize space utilization.

Use Cases

• Terrain analysis and elevation modeling based on 50-meter contour intervals.
• Infrastructure planning and routing based on road and rail network data.
• Land cover and vegetation studies based on mapped natural features.
• Administrative boundary verification based on included boundary information.

Strengths

• Covers the entire continent of Australia with 516 standard map sheets.
• Provides the largest scale (1:250,000) for published topographic maps covering the entire continent.
• Includes multiple datums (GDA94, GDA2020, AHD) and a UTM projection for coordinate accuracy.

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.
