Bremer Bay SI50-12: Topographic Map of Australia at 1:250,000 Scale

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 roads, vegetation, hydrography, and contours. The data is produced by Geoscience Australia and was last updated in March 2026.

Use Cases

• Perform terrain analysis based on 50-meter contour intervals mentioned in the description.
• Map transportation networks based on road and rail infrastructure features.
• Analyze land cover and hydrology based on vegetation and hydrography data.
• Support regional planning based on administrative boundaries and localities.

Strengths

• Covers the entire continent of Australia with 516 maps.
• Provides topographic detail at a scale of 1:250,000, the largest scale covering the entire continent.
• Includes multiple coordinate datums (GDA94, GDA2020, AHD) and uses the Universal Transverse Mercator projection.

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.
