Minigwal SH51-07: 1:250,000 Scale Digital Topographic Map of Australia

516 maps comprise the AUSTopo series, the largest-scale topographic map series covering the entire Australian continent. Each standard map sheet covers an area of approximately 1.5 degrees longitude by 1 degree latitude, showing natural and constructed features like infrastructure, vegetation, and 50-meter contours. Geoscience Australia produces these maps, which use GDA94/GDA2020 datum and UTM projection, with the last update recorded for 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 other data layers based on standardized geographic coverage.

Strengths

• Covers the entire Australian continent at a consistent 1:250,000 scale.
• Comprises 516 map sheets, with each standard sheet covering approximately 150 km east-west by 110 km north-south.
• Includes multiple geographic datums (GDA94, GDA2020) and a standard projection (UTM).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The map may contain information from surrounding sheets, which could affect precise boundary analysis.
