Publisher: U.S. Environmental Protection Agency Online_Linkage: For BASINS model and hydrographic data http://www.epa.gov/waterscience/basins/ Description: Abstract: This data set provides the location of populated places as represented on USGS topographic maps. It includes a collection of populated place names derived from USGS Geographic Names Information System II (GNISII) Topographic Names data. For distribution with BASINS v.2.0, the data layer was prepared in Arcview shape file format. Purpose: This data set was created to provide the location of populated places in the United States in order to establish their proximity to surface waters. The relationship between populations potentially affected by water quality problems can then be established. It will also aid in the determination of the sources of water quality problems. Supplemental_Information: Intended_Use_Of_Data: This data set was prepared to support the U.S. EPA BASINS (Better Assessment Science Integrating Point and Nonpoint Sources) System.

"Geographic Names Information System" http://geonames.usgs.gov/domestic/ Limitations_of_Data: None Procedures: The source data were obtained as State ASCII files on 9-track tape from the USGS. The ASCII files were first converted into ARC/INFO point coverages with an ARC/INFO AML program. The AML program assigned a spatial accuracy code to each point depending upon the degree of its geographical coordinate agreement with USGS 7.5" quadrangle, county and state coverages. The data were checked for spatial accuracy to 7.5" USGS quad level, except for Alaska, Hawaii (a 7.5" USGS quad boundary coverage for these areas) and Colorado (GNIS II data did not contain quadrangle names). The majority of the names were compiled from 1:24,000 scale, 7.5-minute topographic maps. When there were no published 7.5 minute maps or advance copies with names available, 15 minute maps were used; when there was no coverage by either series maps, 1:250,000-scale maps were used. After Phase I data compilation, the geographic names in each State file were edited by comparing computer files with the accumulated records of the U.S. Board on Geographic names (BGN) on a one-to-one basis. When the initial edit of the geographic names in the state file was completed, the corrections were made, and other information such as variant names and BGN data were added. The quality assurance of the enhanced data consisted of checking accuracy codes equal to 1, 3 and 9. An accuracy code with a value of 1 means that the 7.5" quadrangle boundaries that the point's geographic coordinates fell within matched the points associated 7.5" quadrangle name. An accuracy code value is equal to 9 if the point's coordinates are outside the United State borders. Anything on the border of the U.S. and touching the correct county was reassigned an accuracy of 4. An accuracy code value is equal to 3 if the point is outside the associated state border but still inside the U.S. borders. Anything on the point's associated state boundary and touching the correct county was also given an accuracy of 4. The state coverages were also checked against each other to ensure data format consistency throughout the country. For distribution with BASINS v2.0, the ARC/INFO coverages in BASINS v1.0 that included the spatial extent of each of the ten U.S. EPA Regions, plus the 8-digit hydrologic units that crossed region boundaries were reprojected from Albers to Geographic projection and converted to ARCVIEW shapefiles.

Completeness_Report: See Supplemental_Information Lineage: Process_Step: Process_Description: The BASINS v.1.0 data in Arc/Info coverage format and Albers Conic Equal Area projection with datum NAD27 was converted to geographic decimal degrees projection with datum NAD83 using Arc/Info. The coverages were then converted to Arcview shape files using the Arc/Info ARCSHAPE command. For distribution with BASINS 2.0, the DWS data layer were divided by EPA regions (i.e. distribution by CD). Other form of data distribution (e.g. by cataloging unit) is available through the web (http://www.epa.gov/waterscience/basins/).
