**摘要**
本数据集由生物区域评估计划（Bioregional Assessment Programme）从HUN流域数据集（HUN Catchments dataset）衍生而来。本元数据（metadata）声明的"谱系（Lineage）"字段中已标注源数据集信息，而生成该衍生数据集所采用的处理流程则记录于本元数据声明的"历史（History）"字段中。
本数据集涵盖亨特次区域内主要河流及其主要支流的流域面积，并以平方千米为单位，定义了以下各流域的面积。
Hunter:
穆南溪（Moonan Brook）
斯图尔特溪（Stewarts Brook）
帕特森河（Paterson River）
威廉姆斯河（Williams River）
佩奇溪（Pages Creek）
佩奇河（Pages River）
古尔本河（Goulburn River）
沃洛姆比溪（Wollombi Brook）
Macquarie Tuggerah:
多拉溪（Dora Creek）
怀永河（Wyong River）
奥林巴溪（Ourimbah Creek）
## **数据集历史**
本数据集对应亨特次区域内主要河流及其主要支流的流域面积，相关面积已在背景说明的表格中列明，并通过投影形状文件（shapefile）Hunter_Major_Tributaries_Projected.shp计算得到。
该投影形状文件由亨特流域形状文件衍生而来，具体方式为汇总以下选定流域，再按照下述信息进行投影转换：
PROJCS["GDA_1994_Albers",GEOGCS["GCS_GDA_1994",DATUM["D_GDA_1994",SPHEROID["GRS_1980",6378137.0,298.257222101"]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Albers"],PARAMETER["False_Easting",0.0],PARAMETER["False_Northing",0.0],PARAMETER["Central_Meridian",132.0],PARAMETER["Standard_Parallel_1",-18.0],PARAMETER["Standard_Parallel_2",-36.0],PARAMETER["Latitude_Of_Origin",0.0],UNIT["Meter",1.0]]
以下为需汇总的选定流域：
Hunter
穆南溪（Moonan Brook）
斯图尔特溪（Stewarts Brook）
帕特森河（Paterson River）
威廉姆斯河（Williams River）
佩奇溪（Pages Creek）
佩奇河（Pages River）
古尔本河（Goulburn River）
沃洛姆比溪（Wollombi Brook）
Macquarie Tuggerah
多拉溪（Dora Creek）
怀永河（Wyong River）
奥林巴溪（Ourimbah Creek）
