Abminga 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, depicting features like road infrastructure, vegetation, hydrography, and 50-meter contour intervals. The data uses GDA94/GDA2020 datum and UTM projection.

Use Cases

• Extract road and rail infrastructure features from map sheets for transportation network analysis.
• Analyze hydrography and 50-meter contour interval data for watershed modeling and terrain assessment.
• Use vegetation and locality data from the 516-map series for regional environmental and land-use studies.

Strengths

• Covers the entire continent of Australia with 516 map sheets.
• Provides topographic detail at a standardized 1:250,000 scale, the largest scale for full continental coverage.
• Includes both natural and constructed features such as contours, hydrography, and infrastructure.

Limitations

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