Nabberu SG51-05: 1:250,000 Scale Digital Topographic Map of Australia

516 maps comprise the AUSTopo series, which covers the entire continent of Australia at a scale of 1:250,000. Each standard map 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 digital PDF format with coordinates in GDA94, GDA2020, and AHD datums.

Use Cases

• Perform terrain analysis based on 50-meter contour intervals mentioned in the description.
• Map transportation networks based on road and rail infrastructure features.
• Conduct hydrological studies based on hydrography and water feature data.
• Analyze land cover and vegetation patterns across different regions of Australia.
• Create custom base maps for field surveys or regional planning based on standardized topographic features.

Strengths

• Covers the entire Australian continent with 516 map sheets.
• Represents the largest scale (1:250,000) for published topographic maps covering the whole continent.
• Contains multiple feature types including infrastructure, vegetation, hydrography, and contours.

Limitations

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