Torrens Topographic Map at 1:250,000 Scale for Australia

2026-updated digital topographic map covering a standard area of approximately 150 km east-west by 110 km north-south. It is part of a 516-map series representing the largest-scale topographic coverage of the entire Australian continent, showing natural and constructed features including infrastructure, vegetation, and hydrography.

Use Cases

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

Strengths

• Part of a standardized series of 516 maps providing continent-wide coverage.
• Map scale of 1:250,000 offers detailed representation of terrain and features.
• Includes multiple coordinate datums (GDA94, GDA2020) and AHD for vertical reference.

Limitations

• Data is provided only in PDF format, requiring extraction for structured geospatial analysis.
• Map may contain information from surrounding sheets, potentially complicating precise boundary definition.
• Sample data and structured column metadata are unavailable for automated processing.
