Yardea Topographic Map at 1:250,000 Scale Covering Australia

516 digital topographic maps provide coverage of the entire Australian continent at a scale of 1:250,000. Each standard map sheet covers approximately 1.5 degrees longitude by 1 degree latitude, depicting natural and constructed features. The series is produced by Geoscience Australia and includes both standard and approximately 50 special maps for non-standard areas.

Use Cases

• Extract road and rail infrastructure features for national transportation network analysis.
• Analyze hydrography and 50-meter contour intervals for watershed modeling and terrain studies.
• Identify vegetation coverage and administrative boundaries for land-use planning and environmental monitoring.
• Georeference map sheets using GDA94/GDA2020 coordinates and UTM projection for integration into GIS platforms.

Strengths

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

Limitations

• Data is provided in PDF format, requiring extraction for analytical use.
• Map sheets may contain information from surrounding sheets, potentially complicating precise area analysis.
• Approximately 50 maps cover non-standard areas, which may require special handling for tiling.
