Bega Topographic Map at 1:250,000 Scale Covering Australia

AUSTopo's Bega SJ55-04 is a digital topographic map from the Australian Digital Topographic Map Series. The series comprises 516 maps covering the entire continent at a scale of 1:250,000, where 1 cm represents 2.5 km on the ground. Each standard map sheet covers an area of approximately 1.5 degrees longitude by 1 degree latitude.

Use Cases

• Extract road and rail infrastructure features for regional transportation network analysis.
• Analyze hydrography and 50m interval contours for watershed modeling and terrain assessment.
• Identify vegetation coverage and administrative boundaries for land-use planning studies.
• Georeference map features using GDA94/GDA2020 coordinates and UTM projection for GIS integration.

Strengths

• Covers the entire continent of Australia with 516 maps in the complete series.
• Provides topographic detail at a standardized 1:250,000 scale, the largest scale for full continental coverage.
• Contains multiple feature types including infrastructure, hydrography, vegetation, and contours.

Limitations

• Data is provided in PDF format, requiring extraction and conversion for programmatic geospatial analysis.
• Map sheets may contain information from surrounding sheets, potentially complicating precise feature boundary identification.
• Sample data and specific column/attribute schemas are unavailable for review prior to download.
