Geoscience Australia Data publishes the AUSTopo - Australian Digital Topographic Map Series, covering the entire continent at a 1:250,000 scale with 516 maps. The Geraldton Special SH50-01 map is one of approximately 50 special maps in the series, covering a non-standard area and containing natural and constructed features like infrastructure, vegetation, hydrography, and 50m contours. The map is available as a digital PDF download with coordinates in GDA94, GDA2020, and AHD datums using a UTM projection.
Use Cases
- Terrain analysis and elevation modeling based on 50-meter contour intervals
- Infrastructure planning and routing based on road and rail network data
- Environmental and land cover studies based on vegetation and hydrography features
- Geographic reference and boundary verification based on localities and administrative boundaries
Strengths
- Covers the entire Australian continent at the largest published topographic scale (1:250,000)
- Series comprises 516 standard maps and approximately 50 special maps for non-standard areas
- Contains multiple natural and constructed feature layers including contours, infrastructure, and vegetation
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
