Yarraloola SF50-06: 1:250,000 Scale Digital Topographic Map of Australia

516 maps comprise the AUSTopo series, the largest-scale published 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 infrastructure, vegetation, and contours. The data is provided by Geoscience Australia in digital PDF format with coordinates in GDA94, GDA2020, and AHD datums.

Use Cases

• Plan infrastructure projects based on detailed road, rail, and hydrography information.
• Conduct terrain analysis for environmental studies using 50-meter contour intervals.
• Create regional base maps for land management based on combined vegetation and administrative boundary data.
• Perform spatial analysis for emergency response planning using the standardized 1:250,000 scale map series.

Strengths

• Covers the entire Australian continent at a consistent 1:250,000 scale, the largest scale for full coverage.
• Comprises 516 individual map sheets, with each standard sheet covering approximately 150 km east-west by 110 km north-south.
• 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 without conversion.
• Column-level documentation is absent; field semantics must be inferred after download.
• The map may contain information from surrounding sheets, which could affect precise boundary definitions.
