Boulia Topographic Map at 1:250,000 Scale Covering Australia

516 digital maps cover the entire continent of Australia at a scale of 1:250,000, where 1 cm represents 2.5 km. Each standard map sheet covers an area of approximately 1.5 degrees longitude by 1 degree latitude, showing natural and constructed features. The series is produced by Geoscience Australia and includes about 50 special maps covering non-standard areas.

Use Cases

• Analyze road and rail infrastructure density and connectivity across the mapped region.
• Extract hydrography and contour data with a 50m interval for terrain and watershed modeling.
• Identify vegetation cover and administrative boundary information for land-use planning.
• Combine map sheets where standard sheets are largely ocean to maximize spatial data coverage.

Strengths

• Covers the entire continent of Australia with 516 map sheets, providing complete national coverage.
• Operates at a scale of 1:250,000, the largest scale for published topographic maps covering Australia.
• Includes approximately 50 special maps designed for non-standard areas to optimize data presentation.

Limitations

• Data is provided in PDF format only, which is not natively structured for direct geospatial analysis.
• Map sheets may contain information from surrounding sheets, which could complicate precise boundary-based queries.
