2010 Index of Stream Condition - Stream Bed Width 100m Section Summary Table

Abstract:
The ISC_STREAMBED_WIDTH_S table is the Statistical Summary table for the Streambed Width metric at the 100m Section level.
River condition in Victoria is assessed every 5 years using the Index of Stream Condition (ISC). The Department of Environment and Primary Industries (DEPI) developed a methodology to assess the Physical Form and Riparian Vegetation components of the ISC using remote sensing data, specifically LIDAR and aerial photography.
A State Wide mapping project was undertaken in 2010-13 to accurately map the Physical Form and Riparian Vegetation metrics of the ISC . Other ISC metrics were not assessed in the project and were derived from other sources.
The Physical Form and Riparian Vegetation Metric products are a combination of mapped Vector and Raster data as well as Tabular Summary Statistics about the mapped features. In the context of the project, the term Metrics is used to refer to both the mapped features and the summary statistics.
Remote sensing data used includes 15cm true colour and infra-red aerial photography and four return multi-pulse LiDAR data. This source data was used to derive a variety of Raster data sets including Digital Terrain Models, Slope, Vegetation Height and Vegetation Cover. The Digital Terrain and Slope rasters were used to map Physical Form metrics including Stream Bed, Top of Bank and River Centre Lines while the Vegetation Height and Cover rasters were used to map the Riparian Vegetation metrics.
The Project Report "Aerial Remote Sensing for Physical Channel Form and Riparian Vegetation Mapping" describes the remote sensing and mapping approach used to create this data set.

The purpose of the Streambed_Width_S table is to summarise the Streambed Width attributes at the 100m Section level.

Attribute Accuracy:
The UniqueID that describes the Basin, Reach and Section Number for each Section is complete for every Section. Every Section has been summarised.
Logical Consistency:
Every Section is represented in the table. The ISC_STREAMBED_WIDTH_S can be joined to the The ISC_RIVER_CENTRELINES_S feature class.
Data Source:
Dataset Source: The Streambed Width Summary table was programatically generated based on analysis of ISC2010_STREAMBED_WIDTH_R feature class and ISC2010_CHANNEL_TRANSECTS.
