Yanrey Special SF50-09: 1:250,000 Scale Australian Topographic Map

516 maps comprise the AUSTopo series, which covers the entire continent of Australia at a scale of 1:250,000. This special map, Yanrey SF50-09, is one of about 50 non-standard sheets in the series, produced by Geoscience Australia. It contains natural and constructed features including infrastructure, vegetation, hydrography, and 50-meter contour intervals.

Use Cases

• Terrain analysis based on 50-meter contour intervals mentioned in the description
• Infrastructure planning based on road and rail network data
• Environmental and hydrological studies based on hydrography and vegetation features

Strengths

• Covers the entire continent of Australia at its largest published topographic scale (1:250,000)
• Comprises 516 standard maps and about 50 special maps for non-standard areas
• Includes multiple coordinate datums (GDA94, GDA2020, AHD) and UTM projection

Limitations

• Data is provided as a PDF, which is not a machine-readable geospatial format for direct analysis
• Row count and file size are unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
