Hamilton Special Topographic Map of Australia at 1:250,000 Scale

Hamilton Special SJ54-07 is a digital topographic map from the AUSTopo series covering Australia at a 1:250,000 scale. The series comprises 516 standard maps and about 50 special maps, with this sheet containing natural and constructed features like roads, vegetation, and contours. It is produced by Geoscience Australia with coordinates in GDA94/GDA2020 datum and UTM projection.

Use Cases

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

Strengths

• Part of a continent-wide series of 516 topographic maps at Australia's largest published scale.
• Contains multiple feature layers including infrastructure, vegetation, hydrography, and contours.
• Provides coordinates in modern datums (GDA94, GDA2020) and AHD for accurate geospatial reference.

Limitations

• Data is provided as a static PDF, requiring extraction and conversion for analytical or GIS use.
• Map may contain information from surrounding sheets, potentially complicating precise area-based analysis.
• The special map covers a non-standard area, which may not align with typical administrative or research boundaries.
