The data should be displayed and analyzed at scales appropriate for 1:2,000,000-scale data. No responsibility is assumed by the U.S. Geological Survey or the National Atlas of the United States in the use of these data. This map layer contains hydrologic unit boundaries and codes for the United States, Puerto Rico, and the U.S. Virgin Islands. It was revised for inclusion in the National Atlas of the United States of America, and updated to match the streams file created by the USGS National Mapping Division (NMD) for the National Atlas of the United States of America. This is a revised version of the November 2002 map layer. Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. Although this Federal Geographic Data Committee-compliant metadata file is intended to document the map layer in nonproprietary form, as well as in ArcInfo format, this metadata file may include some ArcInfo-specific terminology. Hydrologic Unit Code (HUC) areas in this file do not necessarily match those published in Water-Supply Paper 2294 (Seaber et al). The file has finer resolution than the maps used to determine areas published in the Water-Supply Paper. The ArcInfo version of this file contains two additional annotation layers. One layer is called anno.maplabel1, and contains the first six digits for each accounting unit. The labels for Accounting Regions 1 though 9 have a "0" in front of the number. The second layer is called anno.catnum, and contains the last two digits for each cataloging unit. All numbers were checked manually against a 1:2,000,000-scale plot of the data.
