U.S. National Atlas Water Feature Areas provides the water feature areas for geographic display and analysis at regional and national levels.
Attribute and geospatial data
This file was originally digitized by the National Mapping Division based on the sectional maps contained in 'The National Atlas of the United States of America' published by the USGS in 1970. The 1:2,000,000-scale Digital Line Graph (DLG) data were merged into a single national hydrography coverage. Where necessary to effect the merge, alignment changes were made. The names were taken from the USGS Topographic 1:100,000-scale maps. For Alaska, the names were taken from the USGS Topographic 1:250,000-scale maps. State lines across water bodies were removed from the national coverage. State attributes were assigned to the features. Some spatial features were added and corrected. Some name attributes were added or corrected. All occurrences of St. were changed to Saint. Extra spaces were removed from the attributes. Hydrographic features for Puerto Rico and the U.S. Virgin Islands were added. A minor adjustment was made to the shoreline in Galveston Bay, Texas.
The following steps were performed by ESRI: Downloaded the ArcView Shapefile version of the data, hydrogp020.tar.gz, from http://www.nationalatlas.gov/atlasftp.html and extracted it. Removed unneeded attributes. Removed null records. Reduced the width of attributes. Created ArcGIS™ layer file (.lyr). Created ArcView legend file (.avl). Created projection file (.prj). Ran ArcView Avenue request ExportClean, and created spatial indices.
Metadata imported.
The geospatial part of this data set was originally extracted from the individual 1:2,000,000-scale State boundary Digital Line Graph (DLG) files produced by the U.S. Geological Survey which have a positional accuracy of 1,720 meters. It was updated several times using various sources whose horizontal positional accuracies are unknown.
After processing, the data set is checked for drawing display and number of records and file sizes compared with source materials. Data completeness generally reflects the content of the original Digital Line Graph (DLG) files. Covers only Puerto Rico, the Virgin Islands, the south central, and the eastern half of the US. NBII-SAIN (ed.) created this file by clipping from from ESRI 2002 hydroply.shp. NBII-SAIN website: (http://sain.nbii.gov/).
No duplicate features are present. The shapefile is exported using Avenue request ExportClean. This request verifies and enforces the correctness of shapes.
