Montague Sound Special SD51-12: Australian Topographic Map at 1:250,000 Scale

516 maps comprise the AUSTopo series, the largest-scale topographic map series covering the entire Australian continent. This special map, SD51-12, is one of about 50 non-standard sheets, likely combining land and ocean areas for efficient space use. Produced by Geoscience Australia, it contains natural and constructed features including roads, rail, vegetation, hydrography, and 50-meter contours.

Use Cases

• Perform terrain analysis based on 50-meter contour intervals mentioned in the description
• Map transportation networks based on road and rail infrastructure features
• Analyze coastal and land boundaries based on the special sheet's likely combination of ocean and landward areas
• Conduct regional environmental studies based on vegetation and hydrography data

Strengths

• Covers the entire Australian continent at a consistent 1:250,000 scale
• Comprises 516 standard maps and about 50 special maps for non-standard areas
• Includes multiple geographic datums (GDA94, GDA2020) and projections (UTM)

Limitations

• Data is provided as a PDF, which is not a machine-readable geospatial format for direct analysis
• Row count and specific column-level documentation are unknown
• The description does not specify the exact temporal coverage of the map features
