Widgiemooltha SH51-14: 1:250,000 Scale Digital Topographic Map of Australia

AUSTopo digital topographic map covering the Widgiemooltha area at a scale of 1:250,000. The map series comprises 516 standard sheets covering the entire continent, with each sheet representing an area of approximately 1.5 degrees longitude by 1 degree latitude. It contains natural and constructed features including road and rail infrastructure, vegetation, hydrography, 50m contours, localities, and administrative boundaries.

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 topographic features.

Strengths

• Covers the entire continent of Australia with 516 standard map sheets.
• Provides topographic detail at a consistent scale of 1:250,000, the largest scale covering the whole continent.
• Includes 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 as a PDF, which may require conversion or digitization for direct geospatial analysis.
