Streaky Bay Topographic Map at 1:250,000 Scale

516 maps cover the entire continent of Australia at a 1:250,000 scale, where 1 cm represents 2.5 km on the ground. Each standard map covers an area of approximately 1.5 degrees longitude by 1 degree latitude. The series is produced by Geoscience Australia and was last updated in March 2026.

Use Cases

• Analyze road and rail infrastructure features for transportation network planning.
• Study hydrography and 50m contour intervals for hydrological modeling and flood risk assessment.
• Identify vegetation coverage and administrative boundaries for land-use classification.
• Combine map sheets with landward neighbors for coastal zone management where standard sheets are largely ocean.

Strengths

• 516 maps provide complete coverage of the Australian continent.
• Standard maps cover a consistent area of approximately 150 km east-west and 110 km north-south.
• Contains multiple natural and constructed features including infrastructure, vegetation, and contours.

Limitations

• Data is provided only in PDF format, limiting direct geospatial analysis.
• Specific row counts, column details, and file sizes are unknown.
• The map may contain information from surrounding sheets, which could complicate precise boundary analysis.
