Orford Bay Topographic Map at 1:250,000 Scale

A digital topographic map sheet from the AUSTopo series covering the Orford Bay area of Australia. It is part of a 516-map series providing the largest-scale topographic coverage of the entire continent. The map features natural and constructed details including infrastructure, vegetation, hydrography, and 50-meter contour intervals.

Use Cases

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

Strengths

• Part of a standardized 516-map series covering all of Australia.
• Provides topographic data at the continent's largest published scale of 1:250,000.
• Contains multiple feature types including infrastructure, vegetation, hydrography, and contours.

Limitations

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