ArcHydro global datasets for Idaho StreamStats

This dataset consists of a personal geodatabase containing several vector datasets. This database contains the information needed to link the HUCs together so a watershed may be delineated that spans more than one 8-digit HUC. These datasets may be used with the ArcHydro Tools, developed by ESRI in partnership with the U.S. Geological Survey, StreamStats Development Team. The datasets, together with the ArcHydro Tools and the ArcHydro 8-digit HUC datasets for an area of interest, allow users to delineate watersheds and compute several watershed characteristics.本数据集包含一个个人地理数据库（personal geodatabase），其内集成多份矢量数据集。该数据库存储了关联各水文单元代码（HUC）所需的信息，可用于勾勒跨越多个8位HUC的流域范围。上述数据集可与ArcHydro工具（ArcHydro Tools）配合使用，该工具由ESRI与美国地质调查局、StreamStats开发团队联合开发。将本数据集与目标研究区域对应的ArcHydro工具及ArcHydro 8位HUC数据集相结合，用户即可开展流域勾勒工作，并计算多项流域特征参数。
