Walhallow SE53-07: AUSTopo 1:250,000 Scale Digital Map of Australia

Geoscience Australia Data provides the Walhallow SE53-07 map, part of the AUSTopo - Australian Digital Topographic Map Series. The series comprises 516 standard 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 covers an area of approximately 1.5 degrees longitude by 1 degree latitude, showing natural and constructed features like infrastructure, vegetation, hydrography, and contours.

Use Cases

• Terrain analysis and elevation modeling based on 50m contour intervals.
• Infrastructure planning and routing based on road and rail network data.
• Environmental and land-use studies based on vegetation and hydrography features.
• Creating composite regional maps based on information from surrounding map sheets mentioned in the description.

Strengths

• Covers the entire continent of Australia with 516 standard maps, the largest scale for full coverage.
• Each map covers a standardized area of ~1.5° longitude by 1° latitude (~150 km east-west by 110 km north-south).
• Contains multiple coordinate datums (GDA94, GDA2020, AHD) and uses the Universal Traverse Mercator projection.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided in PDF format, which is not natively machine-readable for analysis.
• Row count is unknown, which may limit suitability assessment for computational tasks.
