Balfour Downs SF51-09: 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 like infrastructure, vegetation, hydrography, and 50-meter contours. The data is provided by Geoscience Australia in PDF format with coordinates in GDA94/GDA2020 datum and UTM projection.

Use Cases

• Terrain analysis and elevation modeling based on 50-meter contour intervals mentioned in the description
• Infrastructure and land-use planning based on depicted road, rail, and administrative boundaries
• Environmental and hydrological studies based on mapped vegetation and hydrography features
• Creating custom map overlays and basemaps based on the standardized 1:250,000 scale topographic data

Strengths

• Covers the entire continent of Australia with 516 map sheets, providing national consistency
• Largest scale (1:250,000) at which published topographic maps cover the entire continent
• Contains multiple feature types including infrastructure, vegetation, hydrography, and contours

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Data is provided only in PDF format, which may limit direct machine-readability and analysis
• The description metadata is limited; actual data quality and completeness require manual inspection after download
