Ouyen SI54-15: AUSTopo 1:250,000 Scale Digital Topographic Map of Australia

AUSTopo - Australian Digital Topographic Map Series provides coverage of the entire continent at a scale of 1:250,000, comprising 516 standard maps. Each standard map covers an area of approximately 1.5 degrees longitude by 1 degree latitude, showing natural and constructed features including infrastructure, vegetation, hydrography, and contours. The data is provided by Geoscience Australia and was last updated in March 2026.

Use Cases

• Regional planning and infrastructure development based on road, rail, and administrative boundary information.
• Environmental analysis and land use studies based on vegetation and hydrography features.
• Creating base maps for navigation and fieldwork based on contours and locality data.
• Combining map sheets for coastal or special area studies based on the description of non-standard sheet combinations.

Strengths

• Covers the entire continent of Australia at its largest published topographic scale (1:250,000).
• Comprises 516 standard maps, each covering a defined area of approximately 150 km by 110 km.
• Contains multiple feature types including infrastructure, vegetation, hydrography, and 50-meter interval contours.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for quantitative analysis.
• Data is provided in PDF format, which may require conversion for direct use in GIS software.
