Nyngan Region Topographic Map at 1:250,000 Scale

AUSTopo digital map series provides topographic coverage of Australia at a 1:250,000 scale, comprising 516 standard maps. Each map covers approximately 150 km east-west and 110 km north-south, depicting natural and constructed features. The series is produced by Geoscience Australia.

Use Cases

• Extract road and rail infrastructure features for regional transportation network analysis.
• Analyze hydrography and 50-meter contour intervals for hydrological modeling and terrain assessment.
• Identify vegetation coverage and localities for environmental and land-use planning studies.
• Combine map sheets with administrative boundaries for jurisdictional mapping and resource management.

Strengths

• Series comprises 516 standard maps covering the entire continent.
• Provides topographic data at the largest scale (1:250,000) published for all of Australia.
• Contains multiple feature types including infrastructure, vegetation, hydrography, and contours.

Limitations

• Data is delivered in PDF format, requiring extraction for quantitative geospatial analysis.
• Map sheets may contain information from surrounding sheets, complicating precise area-specific queries.
• Approximately 50 maps cover non-standard areas, potentially requiring special handling.
