Geoscience Australia Data provides the Burra SI54-05 map from the AUSTopo - Australian Digital Topographic Map Series. This series comprises 516 maps covering the entire continent at a scale of 1:250,000, where 1 cm represents 2.5 km on the ground. Each standard map sheet covers approximately 1.5 degrees longitude by 1 degree latitude, depicting natural and constructed features like roads, vegetation, hydrography, and 50-meter contours.
Use Cases
- Terrain analysis and elevation modeling based on contour data with a 50-meter interval.
- Infrastructure planning and routing based on depicted road and rail networks.
- Environmental and land cover studies based on vegetation and hydrography features.
- Creating regional base maps for other data overlays based on standardized geographic coverage.
Strengths
- Covers the entire Australian continent with 516 map sheets, providing national consistency.
- Represents the largest scale topographic map series published for the entire continent.
- Contains multiple coordinate datums (GDA94, GDA2020) and uses the Universal Transverse Mercator projection.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Data is provided in PDF format, which may require conversion for direct geospatial analysis.
- Row count is unknown, which may limit suitability assessment for bulk processing.
