Why was the data set created?

U.S. National Atlas Water Feature Areas provides the water feature areas for geographic display and analysis at regional and national levels.


How was the data set created?

  1. From what previous works were the data drawn?

    National Atlas (source 1 of 1)
    National Atlas of the United States and the United States Geological Survey, 19991109, nationalatlas.gov - - Water Features:, United States Geological Survey, Reston, Virginia, USA.

    Online Links:

    Type_of_Source_Media: online
    Source_Scale_Denominator: 2000000
    Source_Contribution: Attribute and geospatial data

  2. How were the data generated, processed, and modified?

    Date: 1999 (process 1 of 3)
    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.

    Data sources produced in this process:

    • National Atlas

    Date: 28-Aug-2000 (process 2 of 3)
    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.

    Data sources used in this process:

    • National Atlas

    Data sources produced in this process:

    • hydroply.dbf
    • hydroply.shp
    • hydroply.shx

    Date: 22-Feb-2002 (process 3 of 3)
    The ESRI urban shapefile was clipped to to the extent of the Gulf of Maine surficial sediment GIS project area.

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

  2. How accurate are the geographic locations?

    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.

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    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.

    This is a subset of the original dataset and has been clipped to the extent of the Gulf of Maine surficial sediment GIS project area.

  5. How consistent are the relationships among the observations, including topology?

    No duplicate features are present. The shapefile is exported using Avenue request ExportClean. This request verifies and enforces the correctness of shapes.
