Vegetation width is measured perpendicular to the stream direction using the ISC2010_CHANNEL_TRANSECTS as seed vector up to a distance of 200m from the stream bed. There is a Vegetation Width measurement every 25m. 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. elevation imagery base maps earth cover inland waters transportation ISC2010VEGETATIONWIDTH DWG documentDigital DWG ISC2010VEGETATIONWIDTH DXF documentDigital DXF ISC2010VEGETATIONWIDTH GDB documentDigital GDB ISC2010VEGETATIONWIDTH SHP documentDigital SHP ISC2010VEGETATIONWIDTH MIF documentDigital MIF ISC2010VEGETATIONWIDTH TAB documentDigital TAB ISC2010VEGETATIONWIDTH Extended TAB documentDigital Extended TAB ISC2010_VEGETATION_WIDTH WMS documentDigital WMS ISC2010_VEGETATION_WIDTH WFS documentDigital WFS
