Duchess Topographic Map at 1:250,000 Scale for Australia

AUSTopo digital topographic map sheet covering the Duchess area of Australia at a 1:250,000 scale. The national series comprises 516 standard maps, each covering approximately 1.5 degrees longitude by 1 degree latitude. It is produced by Geoscience Australia and contains features like infrastructure, vegetation, hydrography, and 50-meter contours.

Use Cases

• Extract road and rail infrastructure features for regional transportation network analysis.
• Analyze hydrography and 50-meter contour intervals for watershed and terrain modeling.
• Identify vegetation coverage and administrative boundaries for land-use planning studies.
• Georeference map features using GDA94/GDA2020 datum and UTM projection for spatial integration.

Strengths

• Part of a standardized national series of 516 topographic maps covering the entire continent.
• Contains multiple natural and constructed feature layers including infrastructure, vegetation, and hydrography.
• Provides coordinate data in modern datums (GDA94, GDA2020) and UTM projection.

Limitations

• Data is provided only in PDF format, requiring extraction for geospatial analysis.
• Map may contain information from surrounding sheets, potentially complicating precise area-of-interest isolation.
• The series includes about 50 non-standard area maps, which may differ in coverage from the standard sheets.
