Title: 2010 Index of Stream Condition - Toe of Bank line features
Anzlic ID: ANZVI0803005113
Custodian:
Abstract:
The ISC2010_TOE_OF_BANK line features represent the left and right stream bed lines of the river channel for each River Reach.

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.

Purpose:
The ISC2010_TOE_OF_BANK is captured for the purpose of generating the ISC2010_STREAMBED_WIDTH polygon feature. Toe of Bank lines are captured on each side and then closed at the Reach ends to form the Stream Bed Width polygon.

Beginning to Ending Date: 2010-06-01 - 2012-12-01
Maintainence and Update Frequency: Not planned
Stored Data Format:
Available Format(s) Types: DIGITAL
Positional Accuracy:
+/- 1-2m
Attribute Accuracy:
The UniqueID that describes the Basin and Reach Number is complete for every Reach.
Logical Consistency:
Toe of Bank has been mapped the same way across the entire ISC2010 network. However, the mapping process was by visual interpretation and minor variations in interpreted location of Toe lines may exist.
Data Source:
Dataset Source: The Toe of Bank lines have been mapped from LiDAR derived raster products including Slope and DTM with additional reference to aerial photography. The mapping was a visual interpretation and manual digitisation process.
