Port Augusta Topographic Map at 1:250,000 Scale

516 maps cover the entire continent of Australia at a scale where 1 centimeter represents 2.5 kilometers on the ground. Geoscience Australia produced this series, which includes natural and constructed features like infrastructure, vegetation, and contours. The data was last updated in March 2026.

Use Cases

• Analyzing road and rail infrastructure density across a 1.5 by 1 degree map area for transportation planning.
• Studying vegetation coverage and hydrography features for ecological or watershed management models.
• Using 50-meter interval contours for terrain analysis and slope calculations in geospatial applications.
• Identifying localities and administrative boundaries for demographic or jurisdictional mapping exercises.
• Combining non-standard special map sheets, typically where standard sheets are largely ocean, for coastal region studies.

Strengths

• 516 maps provide complete coverage of the Australian continent.
• Standard maps cover an area of approximately 150 kilometers east-west and 110 kilometers north-south.
• Contains about 50 special maps covering non-standard areas to maximize land feature representation.

Limitations

• The primary format is PDF, which is not inherently structured for direct geospatial analysis without conversion.
• Sample data and specific column definitions are unavailable, limiting understanding of the underlying data model.
• The scale of 1:250,000 may not provide sufficient detail for very localized, high-resolution studies.
