HUN SW Modelling Reaches and HRV lookup 20170106 v01

## **Abstract** \n\nThe dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.\n\n\n\nContains a line shapefile and an excel spreadsheet lookup table. The line shapefile derived from the Geofabric Surface Water Network streams (source data) and spatially represents the reaches described in the accompanying lookup table so that surface water modelling based Hydrological Response Variables (HRVs) can be applied spatially along stream lengths. The interpolation is also applied to the Geofabric Cartographic Streams for mapping purposes.\n\n\n\nv02 of this dataset supersedes this dataset\n\n## **Dataset History** \n\nLine segments from the Geofabric Network Streams and Cartographic Streams source dataset were grouped into reach sections based on descriptions in the accompanying lookup table (supplied by Surface Water Modelling team) using the surface water node locations and described river junctions and other defined locations as spatial reference. Reaches were given a unique ID and dissolved into a multpart lines. There is also a Network version which further breaks the reaches into their Riverine Landscape classes.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2017) HUN SW Modelling Reaches and HRV lookup 20170106 v01.

## **摘要**

本数据集由生物区域评估计划（Bioregional Assessment Programme）基于多份源数据集衍生生成。本元数据声明中的**谱系（Lineage）**字段已标注所用源数据集，而生成该衍生数据集的具体流程则见于元数据声明中的**历史（History）**字段。

本数据集包含矢量线shapefile文件与Excel电子表格查找表。该矢量线shapefile文件源自水文地理构造（Geofabric）地表水网络河道（源数据），在空间上对配套查找表中记载的河段进行可视化呈现，以便将基于地表水建模的水文响应变量（Hydrological Response Variables, HRVs）沿河道长度方向进行空间化应用。此外，为满足制图需求，本数据集还对水文地理构造制图河道进行了插值处理。

本数据集的v02版本已替代当前版本。

## **数据集历史**

本数据集的制作流程为：以地表水建模团队提供的配套查找表中的描述为依据，以地表水节点位置、已标注的河道交汇点及其他预设点位作为空间参考，将水文地理构造网络河道与制图河道源数据中的线段分组为河段单元；为各河段分配唯一标识符，并将其合并为多部分线要素类文件。此外，本数据集还提供网络版本，该版本可将河段进一步按河岸景观类别进行细分。
