2010 Index of Stream Condition - River Centre Lines at the 100 Section Level

dataset: ISC2010_RIVER_CENTRELINES_S
The ISC2010_RIVER_CENTRELINE_S line features represent the set of river reaches that are assessed in the 2010 ISC. This data set is a version of the ISC2010_RIVER_CENTRELINE_R data set where each Reach is divided into 100m Sections. Each 100m Section has Metric Statistics assessed and recorded in Section Summary (_S) Tabes. The ISC2010_RIVER_CENTRELINE_S is designed to JOIN to all ISC2010_<METRIC>_S tables. 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
Metric statistics are collected at 100m section intervals and these can joined to the ISC2010_RIVER_CENTRELINE_SECTION by the "UniqueID" attribute that is defined by a combination of the Basin, Reach and Section number. The ISC2010_RIVER_CENTRELINE_SECTION acts as the spatial key to which all other Physical Form and Riparian Vegetation section metric statistics can be linked.

Quality

Conceptual Consistency
River Centrelines have been mapped the same way across the entire ISC2010 network. The ISC2010_RIVER_CENTRELINE_S is designed to JOIN to all ISC2010_<METRIC>_S tables. 
Missing Data
River Centrelines have been mapped for the entire ISC2010 network. River centrelines have been connected at reach ends and flow direction has been enforced. 
Attribute Quality
The UniqueID that describes the Basin, Reach and Section Number for each Section is complete for every Section. The UniqueID will facilitate a join with any 2010 ISC Section Metric Summary Table. 
Positional Accuracy
+/- 1m 
 

Lineage

Statement
Dataset Source: The Section centre line has been automatically generated from the Reach centre line which in turn has been derived as the mid point of the ISC2010_Stream_Bed_Width polygon feature. The source data for Stream Bed Width is LiDAR derived raster products including Slope and DTM. Dataset Originality: Derived
