Larrimah SD53-13: 1:250,000 Scale Digital Topographic Map of Australia

Geoscience Australia Data provides the Larrimah SD53-13 map as part of the AUSTopo - Australian Digital Topographic Map Series. This series comprises 516 standard maps covering the entire continent at a 1:250,000 scale, 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 including roads, rail, vegetation, hydrography, and 50-meter contours.

Use Cases

• Plan infrastructure projects based on detailed road and rail network data.
• Model terrain and hydrology based on 50-meter contour intervals and hydrography.
• Analyze land cover and administrative boundaries for regional planning.
• Create base maps for field surveys or navigation in remote Australian areas.

Strengths

• Covers the entire Australian continent at its largest published topographic scale.
• Comprises 516 standard map sheets, each covering a consistent area of approximately 150 km east-west by 110 km north-south.
• Contains multiple feature types including infrastructure, vegetation, hydrography, and contours.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided as a PDF, which may require conversion for direct geospatial analysis.
• Freshness should be verified despite the listed last update date of 2026-03-25.
