St Arnaud 1:250,000 Topographic Map of Australia

AUSTopo 1:250,000 digital map sheet covers a standard area of approximately 1.5 degrees longitude by 1 degree latitude. The series comprises 516 maps, providing the largest-scale topographic coverage of the entire Australian continent. It contains natural and constructed features including infrastructure, vegetation, hydrography, and 50-meter contours.

Use Cases

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

Strengths

• Part of a series of 516 maps covering the entire continent of Australia.
• Provides topographic data at the standard 1:250,000 scale, the largest scale for full continental coverage.
• Includes multiple coordinate datums (GDA94, GDA2020, AHD) and UTM projection for geospatial accuracy.

Limitations

• Data is delivered in PDF format, requiring feature extraction or conversion for analytical use.
• Map sheets may contain information from surrounding sheets, potentially complicating precise area-based analysis.
