Poolowanna Topographic Map at 1:250,000 Scale

Geoscience Australia's AUSTopo series provides 516 digital topographic maps covering the entire continent of Australia at a scale of 1:250,000. Each standard map sheet covers an area of approximately 1.5 degrees longitude by 1 degree latitude, representing the largest scale for full continental coverage. The series includes natural and constructed features such as infrastructure, vegetation, hydrography, and contours.

Use Cases

• Analyze road and rail infrastructure networks for transportation planning using the map's feature data.
• Model terrain and elevation for hydrological studies using the 50-meter contour intervals.
• Identify vegetation coverage and land use patterns for ecological assessments.
• Extract administrative boundaries and locality names for demographic or service area mapping.
• Combine map sheets for coastal studies where standard sheets are merged to maximize land area coverage.

Strengths

• Covers the entire Australian continent with 516 map sheets.
• Provides standardized data at a consistent 1:250,000 scale, the largest for full coverage.
• Includes approximately 50 special maps for non-standard areas to optimize data presentation.

Limitations

• Data is provided in static PDF format, limiting direct machine-readability and analysis.
• Specific row counts, file sizes, and detailed column schemas for underlying data are not provided.
• Map sheets may contain information from surrounding sheets, which could complicate precise boundary-based queries.
