Hodgson Downs Topographic Map at 1:250,000 Scale

516 maps constitute the AUSTopo series, the largest-scale topographic coverage for the entire continent of Australia. Each standard map covers an area of approximately 1.5 degrees longitude by 1 degree latitude, depicting natural and constructed features. Geoscience Australia publishes this series, with the data updated in March 2026.

Use Cases

• Analyze road and rail infrastructure density across a 150 km by 110 km map sheet.
• Model terrain using 50-meter interval contour lines for elevation studies.
• Map vegetation coverage and hydrography (water features) for ecological assessments.
• Identify localities and administrative boundaries for regional planning.

Strengths

• Covers the entire continent of Australia with 516 map sheets.
• Provides standardized data at a consistent 1:250,000 scale.
• Includes multiple coordinate datums (GDA94, GDA2020, AHD) and UTM projection.

Limitations

• Data is delivered as PDF files, which are not inherently structured for automated analysis.
• The map may contain information from surrounding sheets, potentially complicating precise area extraction.
• Specific row counts, column structures, and file sizes for the digital data are unknown.
