Australia is covered by 516 topographic maps at a 1:250,000 scale, the largest scale providing continent-wide coverage. Each standard map covers approximately 1.5 degrees longitude by 1 degree latitude, showing natural and constructed features. The series is produced by Geoscience Australia and was last updated in March 2026.
Use Cases
- Plan infrastructure projects based on road and rail network data.
- Analyze terrain and elevation using 50-meter contour intervals.
- Conduct regional environmental studies based on vegetation and hydrography information.
- Perform geographic referencing and mapping using GDA94/GDA2020 datum and UTM projection.
Strengths
- Covers the entire continent of Australia with 516 maps.
- Provides the largest scale (1:250,000) for published topographic maps covering Australia.
- Includes multiple coordinate datums (GDA94, GDA2020, AHD) and a UTM projection.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Data is provided in PDF format, which may require conversion for direct geospatial analysis.
