Norseman SI51-02: 1:250,000 Topographic Map of Australia

516 maps comprise the AUSTopo series, the largest-scale topographic map series covering the entire Australian continent. Each standard map sheet covers an area of approximately 1.5 degrees longitude by 1 degree latitude, showing natural and constructed features like roads, rail, vegetation, hydrography, and 50-meter contours. Geoscience Australia produces this series, 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 1:250,000 scale coverage.

Strengths

• Covers the entire Australian continent at a consistent 1:250,000 scale.
• Contains approximately 516 map sheets, with each standard sheet covering about 150 km east-west by 110 km north-south.
• Includes multiple geographic datums (GDA94, GDA2020, AHD) and UTM projection for accuracy.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided in PDF format, which is not natively machine-readable for analysis.
• Row count is unknown, which may limit suitability assessment for digital processing.
