Australian Digital Topographic Maps at 1:250,000 Scale

516 maps provide coverage of the entire continent of Australia at a scale where 1cm represents 2.5km. Each standard map covers an area of approximately 1.5 degrees longitude by 1 degree latitude, depicting road and rail infrastructure, vegetation, hydrography, and contours. The series is produced by Geoscience Australia.

Use Cases

• Analyze road and rail infrastructure density across different vegetation or hydrography zones.
• Extract contour lines at a 50m interval for terrain modeling and elevation analysis.
• Identify administrative boundaries and localities for regional planning and resource management.
• Combine map sheets for coastal areas where standard sheets are largely ocean with their landward neighbors.

Strengths

• 516 maps provide complete coverage of Australia at its largest published topographic scale.
• Each map contains natural and constructed features including hydrography, vegetation, and contours.
• Coordinates are provided in multiple datums (GDA94, GDA2020) and the Universal Traverse Mercator projection.

Limitations

• Data is provided in PDF format, which requires extraction for geospatial analysis.
• The map may contain information from surrounding sheets, potentially complicating precise area-based queries.
• Sample data and structural details like columns are unavailable for preview.
