Carnarvon Special SG49-04: Australian Topographic Map at 1:250,000 Scale

Australia is covered by this digital topographic map series at a scale of 1:250,000, comprising 516 standard and approximately 50 special map sheets. Each standard sheet covers about 1.5 degrees longitude by 1 degree latitude, showing natural and constructed features like roads, vegetation, hydrography, and 50m contours. The data is provided by Geoscience Australia in PDF format, with coordinates in GDA94/GDA2020 datum and UTM projection.

Use Cases

• Perform terrain analysis based on 50m contour intervals mentioned in the description
• Map infrastructure networks based on road and rail data contained in the map
• Analyze land cover and hydrology based on vegetation and hydrography features
• Support regional planning based on administrative boundaries and localities shown

Strengths

• Covers the entire continent of Australia at its largest published topographic scale
• Comprises 516 map sheets providing systematic coverage
• Includes both natural and constructed features like contours, roads, and vegetation

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Data is provided in PDF format, which may require conversion for geospatial analysis
• Row count is unknown, which may limit suitability assessment
