Average annual runoff in the United States, 1951-80

Gebert, W.A., Graczyk, D.J., and Krug, W.R. 1987 Average annual runoff in the United States, 1951-80 1.0 Series_Name HA Issue_Identification 710 Madison, WI U.S. Geological Survey http://water.usgs.gov/lookup/getspatial?runoff This is a line coverage of average annual runoff in the conterminous United States, 1951-1980. Surface runoff Average runoff Surface waters United States This coverage is intended as a thematic data layer representing average annual runoff, in inches per year, for the conterminous United States. Appropriate maps of the data can show the geographical distribution of runoff in tributary streams for the years 1951-80 and can describe the magnitudes and variations of runoff nationwide. The data was prepared to reflect the runoff of tributary streams rather than in major rivers in order to represent more accurately the local or small scale variation in runoff with precipitation and other geographical characteristics. Information contained in the runoff coverage has been used for several publications. The first is the 1985 National Water Summary (U.S. Geological Survey, 1986), which contained state by state maps (scales 1:3,000,000 to 1:7,500,000) as well as a national map of runoff. The second publication is HA-710 (Gebert and others, 1987). Procedures_Used: Data were compiled in 1985. Streamflow data were collected at over 12,000 gaging stations during 1951-80; 5,951 stations were selected for the analysis. See Gebert and others (1987) for a complete description of how the runoff was determined from the streamflow data. The compilation material was digitized from stable base frosted mylar, using Lambert projection (National Atlas sectionals, 1:2,000,000 scale). Digitizing was completed in March 1987. The digital material was projected to Albers using the following parameters: First parallel: 29 30 00 N Second parallel: 45 30 00 N Central meridian: -96 00 00 W Latitude of projection origin: 23 00 00 N False easting: 0.0 False northing: 0.0 Digitizer units (inches) were transformed to Albers units (meters). Revisions: Procession_Description: Revision 1 Original version of coverage. Process_Date 1987 Reviews_Applied_to_Data: The digital material was checked and corrected for smoothness and accuracy and for reliable uses at scales up to 1:5,000,000. The contours were reviewed during the preparation of the maps in the 1985 National Water Summary (U.S. Geological Survey, 1986) and the maps in HA-710 (Gebert and others, 1987).

Put "None" if there are no restrictions) The coverage should not be used to estimate the streamflow at a specific site. More detailed information can be obtained from streamflow data collected by USGS or other agencies. The digital data is more extensive than either publication (see above) portrays. Only contours with the following values are continuous (that is, no state line faults exist) and some of these contours were not printed if the data was too dense to fit at the publication scale: 1, 2, 5, 10, 15, 20, 25, 30, 40, 60, 80, 100, 120, 160 (Here you acknowledge the agencies and organizations that gave you money, resources, and encouragement to digitize the data and to enter all this wonderful metadata.)

Chain-node topology present. (Information in wordy narrative form describing omissions, selection criteria, generalization, definitions used, and other rules applied to derive the data set) (An explanation of the accuracy of the horizontal coordinate measurements and a description of tests used, if any, to determine horizontal positional accuracy. This is different from horizontal resolution as reported in the DOC file. Positional accuracy defines how correctly the digital features match real-world features and woiuld be related to the concept of the National Map Accuracy Standard -- xx% of well-defined point features fall within xx units of their true position. The resolution is the smallest unit of measure the GIS can reliably manage without truncation or rounding.) approx. 1000 m Resolution as reported (The same as above, but for vertical information that may be encoded with the 2-D features such as cell or contour estimates of a vertical dimension. A description of the contour interval of input data and its basis could be described here.)
