ISC2010 Bare Ground: River Condition Metric Summary for Victoria, 100m Sections

River condition in Victoria is assessed every 5 years using the Index of Stream Condition. The Department of Environment and Primary Industries developed this 2010-13 state-wide mapping project using 15cm aerial photography and LiDAR to derive bare ground metrics. This table provides statistical summaries for the bare ground metric at 100-meter river sections, designed to join with river centerline data.

Use Cases

• Assessing riparian vegetation loss based on bare ground metric summaries.
• Joining statistical summaries to river centerline features for spatial analysis.
• Monitoring changes in river physical form over time using the 5-year assessment cycle.
• Calibrating remote sensing models for vegetation cover using derived LiDAR and aerial photography data.

Strengths

• Derived from high-resolution 15cm true color and infrared aerial photography.
• Uses four-return multi-pulse LiDAR data for terrain and vegetation modeling.
• Part of a state-wide mapping project with a documented methodology in the 'Aerial Remote Sensing for Physical Channel Form and Riparian Vegetation Mapping' report.

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 other sources.
