2010 Index of Stream Condition - Vegetation Width Reach Summary Table

dataset: ISC2010_VEGETATION_WIDTH_R
The VEGETATION_WIDTH_R table is the Statistical Summary table for the Vegetation Width Metric at the Reach level. The ISC2010_VEGETATION_WIDTH_R table is designed to JOIN to the ISC2010_RIVER_CENTRELINES_R feature class. 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 purpose of the Vegetation_Width_R table is to summarise the set of Vegetation Width attributes at the Reach level and to store a Vegetation Width Score for every Reach. Vegetation Width is assessed on the average Width of Vegetation. The Reach Summary Table is designed to facilitate a JOIN with the ISC2010_RIVER_CENTRELINES_R feature class.
