Mount Isa 1:250 000 Scale Digital Topographic Map

516 maps form the largest-scale topographic series covering the entire continent of Australia. Geoscience Australia produced this digital series, which provides coverage of approximately 150 km east-west and 110 km north-south per standard map sheet. The data was last updated in March 2026.

Use Cases

• Analyzing road and rail infrastructure networks across the Mount Isa region for transportation planning.
• Mapping vegetation coverage and hydrography features like rivers and contours for environmental impact studies.
• Identifying localities and administrative boundaries for demographic or land-use research.
• Combining map sheets with landward neighbors to create seamless coastal area maps for maritime studies.

Strengths

• 516 map sheets provide continent-wide coverage at a consistent 1:250,000 scale.
• Each standard map covers a defined area of 1.5 degrees longitude by 1 degree latitude.
• Contours are provided at a 50-meter interval for elevation analysis.

Limitations

• The dataset is delivered as PDF files, which are not directly machine-readable for automated analysis.
• Specific row counts, column structures, and data file sizes are not disclosed.
• Map sheets may contain information from surrounding sheets, potentially complicating precise boundary extraction.
