Hydrographic Stream Network of New South Wales with Strahler Order Classification

New South Wales stream network features, both natural and artificial, classified using the Strahler Stream Order method in 2013. The dataset is a legacy, unmaintained product based on a static 2012 copy of hydrographic data from NSW Spatial Services. Processing was conducted using the RivEX tool and ESRI ArcMap, with workflows designed to ensure continuity across state borders with Queensland and Victoria.

Use Cases

• Modeling hydrological connectivity based on the classified stream network.
• Analyzing stream hierarchy and flow patterns using the Strahler order classification.
• Integrating foundational hydrographic data for regional environmental planning across NSW.
• Conducting cross-border hydrological assessments using data from Queensland and Victoria.

Strengths

• Classification performed using the specialized RivEX tool combined with ESRI ArcMap.
• Processing considered cross-border continuity with data from Queensland and Victoria.
• Dataset is licensed under CC-BY-4.0 for open use.

Limitations

• Dataset is described as a legacy, unmaintained, and best-endeavors product.
• Based on a static 2012 data snapshot, limiting temporal relevance.
• Column-level documentation and sample data are unavailable, requiring manual inspection.
