2010 Index of Stream Condition - Bank Condition 100m Section Summary Table

The ISC2010_BANK_CONDITION_S table is the Statistical Summary table for the Bank Condition Metric at the 100m Section level. The Bank Condition Metric is an assessment of the proportion of the bank face that is eroding above expected rates.\n\nThe ISC2010_BANK_CONDITION_S table is designed to JOIN to the ISC2010_RIVER_CENTRELINES_S feature class.\n\nRiver 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. \n\nA 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.\n\nThe 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. \n\nRemote 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.\nThe 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.

ISC2010_BANK_CONDITION_S表是面向100米河段级别的河岸状况指标统计汇总表。河岸状况指标是对河岸坡面以超出预期速率发生侵蚀的比例进行的评估。

ISC2010_BANK_CONDITION_S表设计用于与ISC2010_RIVER_CENTRELINES_S要素类（feature class）进行关联。

维多利亚州的河流状况每5年通过河流状况指数（Index of Stream Condition, ISC）进行评估。环境与初级产业部（Department of Environment and Primary Industries, DEPI）开发了一套方法，采用遥感数据，具体包括激光雷达（LiDAR）与航空摄影，来评估ISC的物理形态与河岸植被组分。

2010-2013年实施了一项全州制图项目，以精准绘制ISC的物理形态与河岸植被指标。本项目未对其余ISC指标进行评估，相关数据源自其他渠道。

物理形态与河岸植被指标产品是矢量（Vector）与栅格（Raster）制图数据，以及制图要素的表格汇总统计数据的集合。在本项目语境中，“指标”一词同时指代制图要素与汇总统计数据。

所用遥感数据包括15厘米分辨率真彩色与红外航空摄影，以及四回波多脉冲激光雷达（multi-pulse LiDAR）数据。基于该源数据，衍生出多种栅格数据集，包括数字地形模型（Digital Terrain Models, DTM）、坡度、植被高度与植被覆盖度。其中数字地形与坡度栅格被用于绘制包括河床、岸顶与河流中心线在内的物理形态指标，而植被高度与覆盖度栅格则被用于绘制河岸植被指标。

项目报告"Aerial Remote Sensing for Physical Channel Form and Riparian Vegetation Mapping"详细阐述了用于构建本数据集的遥感与制图技术路径。
