Culver SI51-04: Australian Topographic Map at 1:250,000 Scale

Geoscience Australia Data provides the Culver SI51-04 map, part of the AUSTopo - Australian Digital Topographic Map Series. This series comprises 516 standard maps covering the entire continent at a scale of 1:250,000, with each map covering approximately 150 by 110 kilometers. The maps contain natural and constructed features including infrastructure, vegetation, hydrography, and contours, last updated in March 2026.

Use Cases

• Terrain analysis and elevation modeling based on 50-meter contour intervals.
• Infrastructure planning and routing based on road and rail network data.
• Environmental and land cover studies based on vegetation and hydrography features.
• Creating regional base maps for GIS applications based on standardized topographic features.

Strengths

• Covers the entire continent of Australia with 516 standard maps.
• Represents the largest scale at which published topographic maps cover the entire continent.
• Each standard map covers a defined area of approximately 150 by 110 kilometers.
• Contains multiple coordinate datums (GDA94, GDA2020, AHD) and uses UTM projection.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to data_gov_au.
