Hunter bioregion boundary definition sources

## **Abstract** \n\nThe dataset was derived by the Bioregional Assessment Programme. This dataset was derived from multiple datasets. You can find a link to the parent datasets in the Lineage Field in this metadata statement. The History Field in this metadata statement describes how this dataset was derived.\n\n\n\nA line shapefile of the Hunter subregion boundary with line segments attributed with the biophysical feature/dataset that defines that section of the boundary. This dataset is derived from the Bioregional Assessment areas and links to the source datasets are in the lineage field of this metadata statement.\n\n## **Purpose** \n\nTo identify the underlying source used to define the boundary. Mostly the Bioregion boundary was used but some sections are defined by geology and CMA boundaries.For report map purposes.\n\n## **Dataset History** \n\nA polygon shapefile of the Hunter subregion was converted to a line shapefile. The subregion boundary was then compared with the datasets that the subregion metadata listed as boundary sources (see lineage).\n\n\n\nThe subregion boundary line was split (ArcGIS Editor Split tool) into sections that coincided with the source boundary layers and attributed accordingly.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2014) Hunter bioregion boundary definition sources.

## **摘要**

本数据集由生物区域评估计划（Bioregional Assessment Programme）衍生而来，其构建基于多源数据集。元数据声明中的**谱系字段（Lineage Field）**提供了父数据集的链接，而元数据声明中的**历史字段（History Field）**则详细说明了本数据集的衍生流程。

本数据集为亨特次区域边界的线要素shapefile，其各线段均关联了定义该段边界的生物物理特征/数据源。本数据集衍生自生物区域评估区域，其源数据集的链接可在本元数据声明的谱系字段中获取。

## **用途**

本数据集旨在识别用于定义边界的原始数据源。该次区域边界主要采用生物区域边界进行划定，但部分区段由地质要素与流域管理局（Catchment Management Authority, CMA）边界定义。本数据集适用于报告制图场景。

## **数据集历史**

首先将亨特次区域的面要素shapefile转换为线要素shapefile。随后将该次区域边界与元数据中列为边界来源的数据集进行比对（详见谱系字段）。

使用ArcGIS编辑器分割工具（ArcGIS Editor Split tool）将次区域边界线分割为与各源边界图层匹配的区段，并为各分割后的线段添加对应属性。
