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

516 maps comprise the AUSTopo series, the largest-scale topographic map collection covering the entire Australian continent. Each standard map sheet covers approximately 150 by 110 kilometers, depicting road and rail infrastructure, vegetation, hydrography, and 50-meter contours. Geoscience Australia produces these digital PDF maps using 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.
• Combine map sheets where standard sheets are largely ocean to create continuous coastal coverage.

Strengths

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

Limitations

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