Alberga SG53-09 Topographic Map At 1:250,000 Scale

Australia's AUSTopo series provides digital topographic map coverage for the entire continent at a 1:250,000 scale, comprising 516 individual map sheets. Each standard map sheet covers an area of approximately 1.5 degrees longitude by 1 degree latitude, depicting natural and constructed features. The series is produced by Geoscience Australia and includes both standard and approximately 50 special maps for non-standard areas.

Use Cases

• Extract road and rail infrastructure features for transportation network analysis and routing models.
• Analyze hydrography and 50-meter contour intervals for hydrological modeling and terrain assessment.
• Identify vegetation coverage and administrative boundaries for land use classification and planning studies.
• Utilize geographical coordinates in GDA94/GDA2020 datum and UTM projection for precise geospatial alignment in GIS applications.

Strengths

• Covers the entire continent of Australia with 516 map sheets, the largest scale for complete national coverage.
• Each map integrates multiple feature types including infrastructure, vegetation, hydrography, and contours.
• Provides coordinates in modern datums (GDA94, GDA2020) and AHD, with UTM projection for accuracy.

Limitations

• Data is provided in static PDF format, requiring extraction or digitization for quantitative geospatial analysis.
• Map sheets may contain information from surrounding sheets, which could complicate precise feature boundary identification.
• The series includes approximately 50 non-standard special maps, which may have inconsistent spatial extents compared to standard sheets.
