Lennard River Topographic Map at 1:250,000 Scale

516 maps provide full coverage of Australia at a 1:250,000 scale, where 1 cm represents 2.5 km on the ground. Each standard map sheet covers an area of approximately 1.5 degrees longitude by 1 degree latitude, depicting natural and constructed features like hydrography, infrastructure, and 50-meter contours.

Use Cases

• Extract hydrography and contour data for watershed modeling and flood risk analysis.
• Analyze road and rail infrastructure networks for regional connectivity studies.
• Identify vegetation coverage and administrative boundaries for land-use planning.
• Combine map sheets for coastal studies where standard sheets are largely ocean.

Strengths

• Full continental coverage across 516 map sheets.
• Standardized scale of 1:250,000, the largest scale covering all of Australia.
• Contains multiple feature types including infrastructure, vegetation, hydrography, and contours.

Limitations

• Data is provided in static PDF format, requiring extraction for geospatial analysis.
• Contains approximately 50 non-standard area maps, which may complicate seamless tiling.
• Map may contain information from surrounding sheets, potentially affecting feature accuracy at edges.
