Why was the data set created?

These data are intended for geographic display and analysis at the national level, and for large regional areas. 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.

How was the data set created?

1. From what previous works were the data drawn?

   AWUDS (source 1 of 1)

   U.S. Geological Survey, Water Resources of the United States, 2004, AWUDS database.

   Online Links:

   • <http://water.usgs.gov/watuse/data/2000/index.html>

   Type_of_Source_Media: Electronic mail

   Source_Contribution: Spatial and attribute information

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

   Date: Jul-2005 (process 1 of 1)

   The AWUDS data were received as an Excel spreadsheet with data for public supply, industrial, irrigation, livestock, mining, thermoelectric power, and totals for various sources. Minor edits were made and the file was saved as a dBASE IV table.

   Data sources used in this process:

   • AWUDS

3. What similar or related data should the user be aware of?

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

1. How well have the observations been checked?

   AWUDS quality control checks were performed to check for outliers and other data discrepancies. Extensive manual checks were made to check for unexplained trends or data values, and corrections were made as necessary.

2. How accurate are the geographic locations?

3. How accurate are the heights or depths?

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

   This map layer contains information on the estimated use of ground water, surface water, fresh water, saline water and total water use, for public supply, industrial, irrigation, mining, livestock, and thermoelectric power. Statistics are included for the 50 United States, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands.

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

   No tests for logical consistency were performed on this map layer.

How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?

Access_Constraints: None

Use_Constraints:

None. Acknowledgment of the U.S. Geological Survey and (or) the National Atlas of the United States of America would be appreciated in products derived from these data.
