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

Geoscience Australia Data provides the Pinnaroo SI54-14 digital topographic map from the AUSTopo series. It is one of 516 maps covering the entire continent at a 1:250,000 scale, where 1 cm represents 2.5 km on the ground. Each standard map sheet depicts an area of approximately 1.5 degrees longitude by 1 degree latitude.

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 GDA94/GDA2020 coordinates and UTM projection for GIS integration.

Strengths

• Part of a 516-map series providing complete topographic coverage of Australia at its largest published scale.
• Contains detailed natural and constructed features including infrastructure, vegetation, hydrography, and contours.
• Provides coordinates in modern datums (GDA94, GDA2020) and uses the Universal Transverse Mercator projection.

Limitations

• Data is provided as a static PDF, requiring feature extraction for analytical use rather than being a structured tabular dataset.
• Map may contain information from surrounding sheets for layout purposes, which could complicate precise spatial queries.
• The series includes about 50 non-standard area maps, introducing inconsistency in sheet boundaries and coverage.
