Gilgandra 1:250,000 Topographic Map of Australia

Australia's Gilgandra region is covered by this 1:250,000 scale digital topographic map from the national AUSTopo series. The series comprises 516 standard maps covering the entire continent at its largest published scale, with each sheet depicting approximately 150 by 110 kilometers. It contains natural and constructed features including infrastructure, vegetation, hydrography, and 50-meter contours.

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 features using provided GDA94/GDA2020 coordinates and UTM projection for GIS integration.

Strengths

• Part of a national series of 516 maps providing complete coverage of Australia.
• Standard map scale of 1:250,000, the largest scale covering the entire continent.
• Contains multiple feature layers including infrastructure, vegetation, hydrography, and contours.

Limitations

• Data is provided only in PDF format, requiring extraction for structured geospatial analysis.
• Map may contain information from surrounding sheets, potentially complicating precise boundary analysis.
• Sample data and specific row/column counts for feature attributes are unavailable.
