Orroroo Topographic Map At 1:250,000 Scale

516 maps cover the entire continent of Australia at a scale of 1:250,000, the largest scale for full continental coverage. Each standard map sheet covers an area of approximately 1.5 degrees longitude by 1 degree latitude, depicting natural and constructed features including infrastructure, vegetation, and contours.

Use Cases

• Extract road and rail infrastructure features for network analysis and routing applications.
• Analyze hydrography and 50-meter interval contours for watershed modeling and terrain analysis.
• Identify vegetation coverage and administrative boundaries for land use planning studies.
• Georeference map sheets using GDA94/GDA2020 coordinates and UTM projection for integration with other spatial datasets.

Strengths

• Covers the entire continent of Australia with 516 map sheets.
• Provides a standardized scale of 1:250,000 for consistent continental analysis.
• Includes multiple coordinate datums (GDA94, GDA2020) and UTM projection.

Limitations

• Data is provided in static PDF format, requiring extraction for vector or raster analysis.
• Map sheets may contain information from surrounding sheets, potentially complicating precise area-based queries.
• Approximately 50 maps cover non-standard areas, introducing variability in sheet boundaries.
