Ninghan SH50-07: AUSTopo 1:250,000 Digital Topographic Map

516 maps covering the entire continent of Australia 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. The data is provided by Geoscience Australia and was last updated in March 2026.

Use Cases

• Plan infrastructure projects based on detailed road, rail, and hydrography information.
• Conduct terrain analysis using 50-meter contour intervals for elevation modeling.
• Perform regional land-use studies based on mapped vegetation and administrative boundaries.
• Create composite maps for coastal areas using special sheets that combine land and ocean data.

Strengths

• Covers the entire continent of Australia with 516 maps, providing national coverage.
• Largest scale (1:250,000) at which published topographic maps cover the entire continent.
• Contains multiple coordinate datums (GDA94, GDA2020, AHD) and uses the UTM 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 large-scale computational tasks.
