Tarcoola 1:250,000 Topographic Map Sheet For Australia

Australia is covered by 516 digital topographic maps at a 1:250,000 scale, the largest scale covering the entire continent. Each standard map sheet depicts an area of approximately 1.5 by 1 degrees, showing natural and constructed features including infrastructure, vegetation, and hydrography. The series is produced by Geoscience Australia.

Use Cases

• Extract road and rail infrastructure features for regional transportation network analysis.
• Analyze hydrography and 50-meter contour intervals for watershed and terrain modeling.
• Identify vegetation coverage and administrative boundaries for land-use planning studies.
• Georeference map sheet data using GDA94/GDA2020 coordinates and UTM projection for GIS integration.

Strengths

• Covers the entire continent of Australia with 516 map sheets.
• Provides standardized 1:250,000 scale mapping, the largest scale for full continental coverage.
• Includes multiple geographic datums (GDA94, GDA2020) and UTM projection for accuracy.

Limitations

• Data is delivered as PDF files, requiring extraction and conversion for analytical use.
• Map sheets may contain information from surrounding sheets, potentially complicating precise area analysis.
• Approximately 50 maps cover non-standard areas, introducing inconsistency in sheet boundaries.
