Busselton Special SI50-05: 1:250,000 Scale Topographic Map of Australia

AUSTopo's 1:250,000 digital map series covers the entire continent of Australia across 516 standard and approximately 50 special map sheets. This special map, Busselton SI50-05, is part of the series produced by Geoscience Australia and contains natural and constructed features including roads, rail, vegetation, hydrography, and 50-meter contours. The data uses GDA94/GDA2020 datum, AHD height datum, and UTM projection, and was last updated on 2026-03 25.

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.
• Create regional base maps for planning based on administrative boundaries and localities.

Strengths

• Covers the entire continent of Australia at its largest published topographic scale (1:250,000).
• Comprises 516 maps providing systematic coverage, with approximately 50 special sheets for non-standard areas.
• Contains multiple feature types including infrastructure, vegetation, hydrography, and contours.

Limitations

• Description metadata is limited; actual data quality and feature completeness require manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred from the PDF file.
• The map may contain information from surrounding sheets, which could affect boundary consistency.
