资源简介：
This vector coverage of hydrography centerlines was derived from
the National Hydrography Dataset (NHD), and encompasses all of Ohio and portions of Indiana,
Michigan, Kentucky, West Virginia, Pennsylvania, and New York. This coverage is comprised of
105 Catalog Units (CUs) obtained from http://nhd.usgs.gov/. Each CU approximately represents
a single 8-digit Hydrologic Unit Code (HUC).
本水文中心线矢量数据集源自美国国家水文数据集（National Hydrography Dataset, NHD），覆盖俄亥俄州全域及印第安纳州、密歇根州、肯塔基州、西弗吉尼亚州、宾夕法尼亚州与纽约州部分区域。该数据集包含105个目录单元（Catalog Units, CUs），数据获取自http://nhd.usgs.gov/。每个目录单元大致对应一个8位水文单元代码（Hydrologic Unit Code, HUC）。
