ISC2010 Bare Ground Metric: River Reach Summary Statistics for Victoria

A statistical summary table for the Bare Ground metric at the river reach level, part of Victoria's 2010 Index of Stream Condition assessment. The Department of Environment and Primary Industries developed the data using remote sensing from 15cm aerial photography and multi-pulse LiDAR collected between 2010 and 2013. This table is designed to join to a river centerlines feature class for spatial analysis.

Use Cases

• Assessing riparian vegetation loss and erosion risk based on bare ground metrics.
• Joining summary statistics to spatial river networks for watershed-scale analysis.
• Benchmarking river condition changes over time using the 5-year ISC assessment cycle.
• Validating remote sensing methodologies for mapping physical stream form.

Strengths

• Derived from high-resolution source data including 15cm aerial photography and four-return multi-pulse LiDAR.
• Part of a state-wide mapping project with a documented methodology described in a project report.
• Data is structured for integration with a spatial river centerlines feature class.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Covers only the Physical Form and Riparian Vegetation metrics; other ISC metrics were derived from separate sources.
