Wiluna SG51-09: Australian Topographic Map at 1:250,000 Scale

A digital topographic map from the AUSTopo series covering the Wiluna region of Australia at a 1:250,000 scale. The series comprises 516 standard maps covering the entire continent, each sheet covering approximately 1.5 degrees longitude by 1 degree latitude. It is produced by Geoscience Australia and contains natural and constructed features including roads, rail, vegetation, hydrography, and 50-meter contours.

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-use studies based on vegetation and hydrography features.
• Geographic reference and base mapping for regional studies based on standardized sheet coverage.

Strengths

• Covers the entire continent of Australia through a standardized series of 516 maps.
• Represents the 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 in PDF format, which may require conversion for direct geospatial analysis.
