Holroyd Special SD54-11: Australian Topographic Map at 1:250,000 Scale

AUSTopo digital topographic map covering a non-standard area of Australia at a scale of 1:250,000. It is part of a series of 516 maps, with approximately 50 special maps like this one that combine areas to maximize land coverage. The map shows natural and constructed features including infrastructure, vegetation, hydrography, and 50-meter contours.

Use Cases

• Terrain analysis and visualization based on 50-meter contour intervals.
• Infrastructure planning based on road and rail network data.
• Environmental and land cover studies based on vegetation and hydrography features.
• Creating regional base maps for GIS projects based on standardized topographic symbology.

Strengths

• Part of a standardized national series covering the entire continent of Australia.
• Contains multiple feature classes including contours, infrastructure, vegetation, and hydrography.
• Uses modern geodetic datums (GDA94, GDA2020) and the UTM projection.

Limitations

• Data is provided in PDF format, which is not natively machine-readable for analysis.
• Description metadata is limited; actual data quality requires manual inspection after download.
• The map may contain information from surrounding sheets, which could affect precise boundary definitions.
