Australian Topographic Map at 1:250,000 Scale

516 digital topographic maps cover the entire continent of Australia at a scale of 1:250,000. Each standard map depicts an area of approximately 1.5 degrees longitude by 1 degree latitude. The series is produced by Geoscience Australia and includes natural and constructed features.

Use Cases

• Analyze road and rail infrastructure networks across the continent using the map's transportation features.
• Model terrain and elevation using the 50-meter interval contour lines provided on the maps.
• Assess vegetation coverage and hydrography for environmental studies based on the natural feature data.
• Identify localities and administrative boundaries for regional planning and demographic analysis.
• Combine map sheets for coastal studies where standard sheets are merged with landward neighbors to minimize ocean coverage.

Strengths

• 516 maps provide complete coverage of the Australian continent.
• Standard map sheets cover an area of about 150 km east-west and 110 km north-south.
• The 1:250,000 scale is the largest scale for published topographic maps covering the entire continent.

Limitations

• Data is provided in PDF format, which is not directly machine-readable for analysis.
• The exact number of rows, columns, and sample data for underlying vector data is unknown.
• Map sheets may contain information from surrounding sheets, which could complicate precise boundary analysis.
