Napperby 1:250,000 Topographic Map Of Australia

516 digital maps provide complete topographic coverage of Australia at a scale of 1:250,000. The series, produced by Geoscience Australia, depicts natural and constructed features like hydrography, infrastructure, and 50-meter contours. Each standard map sheet covers an area of approximately 1.5 degrees longitude by 1 degree latitude.

Use Cases

• Extract hydrography and contour features for watershed modeling and flood risk analysis.
• Analyze road and rail infrastructure networks for regional connectivity studies.
• Use the 50-meter contour interval data for terrain visualization and elevation profiling.
• Combine map sheets with administrative boundaries for land-use planning assessments.

Strengths

• Covers the entire continent of Australia with 516 map sheets.
• Provides data at the largest published scale (1:250,000) for full continental coverage.
• Includes both natural features (vegetation, hydrography) and constructed features (infrastructure).

Limitations

• Data is provided only in PDF format, requiring extraction for geospatial analysis.
• Map sheets may contain information from surrounding sheets, complicating precise boundary-based queries.
• Approximately 50 maps cover non-standard areas, which may require special handling for tiling.
