Alligator River 1:250,000 Topographic Map of Australia

Geoscience Australia Data provides the Alligator River SD53-01 map from the AUSTopo series. This digital PDF map covers a standard area of approximately 150 by 110 kilometers at a scale of 1:250,000, depicting natural and constructed features. The series comprises 516 maps, which is the largest scale topographic coverage for the entire Australian continent.

Use Cases

• Extract road and rail infrastructure features for regional transportation network analysis.
• Analyze hydrography and 50-meter contour intervals for watershed modeling and flood risk assessment.
• Identify vegetation coverage and administrative boundaries for land-use planning and conservation studies.

Strengths

• Covers the entire Australian continent through a series of 516 individual map sheets.
• Provides a standardized scale of 1:250,000, with each map covering approximately 150 by 110 kilometers.
• Contains multiple data layers 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 areas, potentially complicating precise boundary-based queries.
