Frew River 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 sheet depicts an area of approximately 1.5 degrees longitude by 1 degree latitude, containing features like road infrastructure, vegetation, hydrography, and 50-meter contours. The series is produced by Geoscience Australia.

Use Cases

• Extract road and rail infrastructure features for transportation network analysis.
• Analyze hydrography and 50-meter contour intervals for terrain and watershed modeling.
• Identify vegetation coverage and administrative boundaries for land-use planning.
• Combine map sheets for non-standard coastal areas to create continuous coastal zone maps.

Strengths

• Covers the entire continent of Australia with 516 map sheets.
• Provides the largest scale (1:250,000) topographic coverage for Australia.
• Includes multiple coordinate datums (GDA94, GDA2020) and UTM projection.

Limitations

• Data is provided only in PDF format, requiring extraction for geospatial analysis.
• Map sheets may contain information from surrounding sheets, complicating precise tile-based analysis.
• Sample data and structural metadata (like columns) are unavailable for review.
