Newdegate SI50-08: Australian Topographic Map at 1:250,000 Scale

AUSTopo's Newdegate SI50-08 is a digital topographic map from a series of 516 maps covering the entire continent of Australia at a scale of 1:250,000. Each standard map covers an area of approximately 1.5 degrees longitude by 1 degree latitude, showing natural and constructed features including infrastructure, vegetation, hydrography, and contours. The map is provided by Geoscience Australia Data in PDF format with coordinates in GDA94, GDA2020, and AHD datums.

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-use studies based on vegetation and hydrography features.
• Creating regional base maps for GIS projects based on standardized sheet coverage.

Strengths

• Covers the entire continent of Australia as part of a consistent series of 516 maps.
• Represents the largest scale (1:250,000) at which published topographic maps cover the entire continent.
• Contains multiple feature types including infrastructure, vegetation, hydrography, and administrative boundaries.

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.
