Roper River SD53-11: AUSTopo 1:250,000 Digital Topographic Map

AUSTopo is a digital topographic map series covering the entire continent of Australia 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 infrastructure, vegetation, hydrography, and 50m contours. The data is provided by Geoscience Australia and was last updated in March 2026.

Use Cases

• Terrain analysis and elevation modeling based on 50-meter contour intervals.
• Infrastructure planning and routing based on depicted road and rail networks.
• Landscape and vegetation studies based on featured natural and constructed land cover.
• Geographic reference and boundary checking based on administrative boundaries and localities.

Strengths

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

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The primary file format is PDF, which may require conversion for direct geospatial analysis.
• Data may reflect geographic bias inherent to data_gov_au as a single national source.
