Avon Downs Topographic Map at 1:250,000 Scale

516 maps comprise the AUSTopo series, the largest-scale topographic map series covering the entire continent of Australia. Each standard map sheet covers an area of approximately 1.5 degrees longitude by 1 degree latitude, showing natural and constructed features including infrastructure, vegetation, and 50-meter contours. The data uses GDA94/GDA2020 datum and UTM projection.

Use Cases

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

Strengths

• Covers the entire continent of Australia with 516 map sheets.
• Provides the largest scale (1:250,000) for published topographic maps of Australia.
• Contains multiple feature types including infrastructure, vegetation, hydrography, and contours.

Limitations

• Data is provided only in PDF format, requiring extraction for structured geospatial analysis.
• Map sheets may contain information from surrounding sheets, potentially complicating precise boundary analysis.
• Approximately 50 maps cover non-standard areas, introducing inconsistency in sheet dimensions.
