Australian Topographic Maps at 1:250,000 Scale

516 maps cover the entire continent of Australia at a scale where 1cm represents 2.5km. Each standard map depicts an area of approximately 1.5 degrees longitude by 1 degree latitude, showing natural and constructed features. The series is produced by Geoscience Australia.

Use Cases

• Extract road and rail infrastructure features from map PDFs for transportation network analysis.
• Analyze hydrography and contour data with a 50m interval for hydrological or terrain modeling.
• Combine vegetation and locality information from multiple map sheets for regional land-use studies.
• Use geographical coordinates and UTM projection data for geospatial alignment with other datasets.

Strengths

• 516 maps provide complete coverage of the Australian continent.
• Standard map sheets cover a consistent area of about 150 km east-west and 110 km north-south.
• Features include multiple data types: infrastructure, vegetation, hydrography, contours, and administrative boundaries.

Limitations

• Data is provided only in PDF format, requiring extraction for computational analysis.
• The map series includes about 50 special maps covering non-standard areas, complicating systematic processing.
• Map sheets may contain information from surrounding sheets, potentially creating overlap or boundary inconsistencies.
