Derby SE51-07: AUSTopo 1:250,000 Scale Digital Topographic Map

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

• 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 topographic symbology.

Strengths

• Covers the entire continent of Australia with 516 map sheets.
• Represents the largest scale (1:250,000) at which published topographic maps cover all of Australia.
• Contains multiple feature classes including infrastructure, vegetation, hydrography, and contours.

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.
• Row count is unknown, which may limit suitability assessment.
