Chowilla Topographic Map at 1:250,000 Scale

AUSTopo 1:250,000 digital map series provides topographic coverage for the entire continent of Australia. Geoscience Australia Data produced the series, which comprises 516 standard maps and about 50 special maps. The Chowilla sheet was last updated in March 2026.

Use Cases

• Analyze road and rail infrastructure networks across the Chowilla region.
• Model terrain elevation using contour lines at a 50-meter interval.
• Identify hydrography features like rivers and water bodies for hydrological studies.
• Assess vegetation cover types for ecological or land management applications.
• Map administrative boundaries and localities for regional planning.

Strengths

• Covers the entire continent of Australia at its largest published topographic scale.
• Series contains 516 standard maps, each covering approximately 150 km by 110 km.
• Includes natural and constructed features like infrastructure, vegetation, hydrography, and contours.

Limitations

• Data is provided only in PDF format, limiting direct computational analysis.
• Specific row count, column structure, and sample data for the Chowilla sheet are unknown.
• Map may contain information from surrounding sheets, potentially complicating precise boundary analysis.
