Australian Topographic Map at 1:250,000 Scale

Geoscience Australia's AUSTopo series provides 516 digital topographic maps covering the entire continent at a scale of 1:250,000. Each standard map sheet depicts an area of approximately 1.5 degrees longitude by 1 degree latitude, containing natural and constructed features. The series represents the largest scale at which published topographic maps cover all of Australia.

Use Cases

• Extract road and rail infrastructure features for transportation network analysis.
• Analyze hydrography and 50-meter interval contours for hydrological and elevation modeling.
• Identify vegetation coverage and administrative boundaries for land-use planning.
• Georeference map sheets using GDA94/GDA2020 coordinates and UTM projection for spatial integration.

Strengths

• Covers the entire Australian continent with 516 map sheets.
• Provides the largest scale (1:250,000) topographic coverage for the continent.
• Includes both natural and constructed features like infrastructure, vegetation, and contours.

Limitations

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