Broome SE51-06: 1:250,000 Scale Digital Topographic Map of Australia

AUSTopo - Australian Digital Topographic Map Series provides 516 maps covering the entire continent of Australia at a scale of 1:250,000. Each standard map covers an area of approximately 1.5 degrees longitude by 1 degree latitude, showing natural and constructed features like roads, 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 1:250,000 scale coverage.

Strengths

• Covers the entire continent of Australia with 516 map sheets.
• Represents the largest scale (1:250,000) for published topographic maps covering the entire continent.
• Each standard map covers a defined area of approximately 150 km east-west by at least 110 km north-south.

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.
• The description metadata is limited; actual data quality and completeness require manual inspection.
