Cobham Lake SH54-11: Australian Topographic Map at 1:250,000 Scale

516 maps comprise the AUSTopo series, the largest-scale topographic map series covering the entire Australian continent. Geoscience Australia produces these digital maps, which show natural and constructed features like roads, vegetation, and 50-meter contours. The Cobham Lake sheet was last updated in March 2026.

Use Cases

• Terrain analysis and elevation modeling based on 50-meter contour intervals.
• Infrastructure and land-use planning based on depicted road, rail, and administrative boundaries.
• Environmental and hydrological studies based on mapped vegetation and hydrography features.
• Creating regional base maps for other projects based on the standardized 1:250,000 scale coverage.

Strengths

• Covers the entire continent of Australia at a consistent 1:250,000 scale.
• Contains approximately 516 standard map sheets, providing extensive spatial coverage.
• Includes multiple coordinate datums (GDA94, GDA2020) and projections (UTM) for interoperability.

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.
