Illogwa Creek 1:250,000 Topographic Map of Australia

AUSTopo 1:250,000 digital map series provides continent-wide coverage of Australia with 516 standard map sheets. Each standard sheet covers approximately 1.5 degrees longitude by 1 degree latitude, depicting natural and constructed features like hydrography, contours, and road infrastructure. The series is produced by Geoscience Australia and includes about 50 special maps for non-standard areas.

Use Cases

• Extract hydrography and contour data for watershed modeling and flood risk assessment in the Illogwa Creek region.
• Analyze road and rail infrastructure networks for transportation planning and connectivity studies.
• Identify vegetation coverage and administrative boundaries for land-use classification and environmental management.
• Combine map sheet data for coastal regions where standard sheets are largely ocean to create continuous land coverage.

Strengths

• Covers the entire continent of Australia with 516 standard map sheets.
• Provides topographic detail at a scale of 1:250,000, the largest scale for full continental coverage.
• Includes about 50 special maps for non-standard geographic areas to maximize data utility.

Limitations

• Data is provided only in PDF format, requiring extraction for geospatial analysis.
• Map sheets may contain information from surrounding sheets, which could complicate precise boundary analysis.
• The contour interval is 50 meters, which may lack detail for fine-scale elevation modeling.
