<abstract>This data set depicts land use and land cover from the 1970s and 1980s and has been previously published by the U.S. Geological Survey (USGS) in other file formats. This version has been reformatted to other file formats and includes minor edits applied by the U.S. Environmental Protection Agency (USEPA) and USGS scientists. This data set was developed to meet the needs of the USGS National Water-Quality Assessment (NAWQA) Program.</abstract>
<purpose>
Land-use and land-cover data collected by the U.S. Geological Survey are useful for environmental assessment of land-use patterns with respect to water-quality analysis, growth management, and other types of environmental impact assessment.
The data are meant to be normally used by quadrangle, or among adjacent quadrangles where temporally contiguous. The data can be used in any geographic application where intermediate scale land-use data are appropriate and the source land-cover map dates are representative of the time period of interest.
</purpose>
<supplinf>
This data set is released as part of an enhanced version of previously published USGS land-use and land-cover data, edited to perform attribute and geographic corrections, recast to the North American Horizontal Datum of 1983, and reformatted to the commonly used geospatial data file formats.
BACKGROUND
The following background information is extracted from:
U.S. Geological Survey, 1986, Land use and land cover digital data from 1:250,000- and 1:100,000-scale maps: Data User Guide 4, 25 p.
(This document is out of print, but was available online on July 1, 2005 at http://www.vterrain.org/Culture/LULC/Data_Users_Guide_4.html)

> shall have a minimum width of 92 m. For categories other than Urban or
> Built-up Land and Water, the 16-ha minimum size for delineation requires
> a minimum-width polygon of 400 m. Line weight for delineating Land Use

PROCESSING DETAILS
The U.S. Environmental Protection Agency (USEPA) received the USGS land-use and and land-cover data files from USGS in 9-track ASCII format, one file per quadrangle. Files were loaded onto the hard disk of the computer from tape. The data were then processed with the GIRASARC2 program written in Arc Macro Language (AML), which is part of the ArcInfo Geographic Information System (GIS) software. This program was developed by the USGS to process the data into a consistent ArcInfo format.
The GIRASARC2 AML <http://www.epa.gov/ngispgm3/spdata/EPAGIRAS/meta/girasarc2.aml> program does the following:
> -- Converts the USGS data files to polygon coverage format.
> -- Reconstructs topology, creating line and polygon features.
> -- Linearly scales the map coordinates to UTM using the registration points
> listed in the USGS data file, and then modifies the coordinates to
> Albers Equal Area projection.
> -- Generates a quadrangle boundary polygon based on the mathematically-determined
> corners of the map.
> -- Loads available documentation into a series of companion documentation
> files with each data set.
>
Another AML program (GIRASNEAT, <http://www.epa.gov/ngispgm3/spdata/EPAGIRAS/meta/girasneat.aml>) does the following:
> --clips the data to the neatline data set.
> --dissolves polygon boundaries between polygons with the same land use code.
> --snaps exterior arcs to the arcs of the neatline cover with a tolerance of
> 40 meters.
Data were reviewed visually by the user responsible for executing the GIRASARC2 program.
The GIRASARC2 and GIRASNEAT programs were executed in AML to create each quadrangle data set.
The processing described above was completed by the USEPA in the early 1990s. In 2001, the USGS National Water-Quality Assessment (NAWQA) Program needed a seamless data base of the conterminous United States, so data sets were further enhanced for use in the Program, as described below.
Additional land use and land cover data sets for Hawaii and one map sheet in Alaska were converted using the same AML programs and edited in a similar manner. The Hawaii data sets were joined together into a single data set as they all are documented with the same source date and are more easily handled as a single data file.
These data files were then further edited to correct land-use coding errors caused by the misplacement of labels have also been corrected by visual inspection, checking the codes against the original labels in the GIRAS data files and ancillary land-cover data sets. An AML menu-based application was used to assist in this process.
In addition to the processing describe above, the data were processed to fill in all gaps between quadrangles so that the data fits together seamlessly. The polygon data were then transformed so that the horizontal coordinate data reference the North American Datum of 1983. (The raw GIRAS-format data and the USEPA version of it is referenced to the North American Datum of 1927.) The geographic data files were also projected into geographic coordinates (decimal degrees of latitude and longitude). Additional polygon data sets that document the land-use and land-cover data sets in a geographic context were created from the USEPA quadrangle index coverages with further editing based on information in the USGS data files posted on the USGS FTP site at the USGS EROS Data Center at: ftp://edcftp.cr.usgs.gov/pub/data/LULC A summary of this effort was published as: Price, C., Naomi, N., Hitt, K., and Clawges, R., 2003, Mining GIRAS: Improving on a national treasure of land use data, _in_ Proceedings of the 2004 ESRI International User Conference, July 7-11, 2003, Environmental Systems Research Institute, Redlands Calif., 11p., available online at http://gis.esri.com/library/userconf/proc03/p0904.pdf
DATA FILE DESCRIPTIONS
Note that all data sets are referenced to the North American Datum of 1983.
1. tilepoly: Polygons representing each quadrangle tile.
2. src_poly: Polygons representing the extent of source files, with metadata about the source files used for each area. Some land-use files were merged from multiple GIRAS source files, some of which have different source dates.
3. gAABBB: Polygons for each 1:250,000 tile, where "AA" represents the latitude of the lower right corner and "BBB" represents the longitude of the lower right corner of the map tile. These tile names are referenced in the polygon attributes of the tilepoly and src_poly polygon data sets described above.
The polygon data sets above are distributed as a collection of related files that make up the publicly documented ESRI shapefile format:
> filename.shp ESRI shapefile geographic data file
> filename.shx ESRI shapefile index data file
> filename.dbf ESRI shapefile attribute file
> filename.prj "Well-Known-Text" (WTK) format projection file
> filename.shp..xml metadata file
The shapefiles use geographic (decimal degree) coordinate data referenced to the North American Datum of 1983.
4. girasX Raster-format data, stored in six image files,
in GeoTIFF format (with georeferencing included in the
internal image header file).
> IMAGE XMIN YMIN XMAX YMAX DESCRIPTION

The raster data sets are referenced to locations specified in projected coordinates (in meters). Image tiles giras1 through giras4 use standard parameters for the conterminous United States:
> Projection ALBERS
> Datum NAD83
> Units METERS
> Spheroid GRS1980
> Xshift 0.0000000000
> Yshift 0.0000000000
> Parameters
> 29 30 0.000 /* 1st standard parallel
> 45 30 0.000 /* 2nd standard parallel
> -96 0 0.000 /* central meridian
> 23 0 0.000 /* latitude of projection's origin
> 0.00000 /* false easting (meters)
> 0.00000 /* false northing (meters)
giras5 (Hawaii) uses these projection parameters:
> Projection UTM
> Zone 6
> Datum NAD83
> Units METERS
> Spheroid GRS1980
giras6 (Valdez, Alaska) uses these projection parameters:
> Projection UTM
> Zone 4
> Datum NAD83
> Units METERS
> Spheroid GRS1980
The raster data sets are distributed as a collection of related files:
> girasX.tif Tagged-Image Format File (TIFF) with GeoTIFF georeferencing
> girasX.tfw ESRI "World file", used for georeferencing
> girasX.aux ESRI "aux file" file used by ArcGIS software
> girasX.prj ESRI ArcInfo projection file
> girasX.tif.xml metadata file

The ArcInfo EXPORT format data sets were retrieved from the EPA server, and edited by USGS to to correct minor attribute and geography errors, followed by coordinate projection and data format translation. The final data set is seamless and very closely match together at quad boundaries (although exact edgematching processing was not done, only tiny gaps exist between quadrangle tiles).
The quadrangles from Alaska and Hawaii were not available from EPA's collection of EXPORT files. They were downloaded from the USGS EROS ftp site at ftp://edcftp.cr.usgs.gov/pub/data/LULC. The GIRAS format files were converted to ArcInfo Coverage format. The Hawaii files were into a single data ArcInfo coverage, which was was given the tile label G18154.
This work was completed by Curtis Price, Naomi Nakagaki, Kerie Hitt, and Rick Clawges in support of the USGS National Water-Quality Assessment Program. A description of this process has been published in
Price, C., Naomi, N., Hitt, K., and Clawges, R., 2003, Mining GIRAS: Improving on a national treasure of land use data, in Proceedings of the 2004 ESRI International User Conference, Environmental Systems Research Institute, Redlands Calif. [on-line] (Accessed November 3, 2004, from http://gis.esri.com/library/userconf/proc03/p0904.pdf)

NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) Local resolution NHD is being developed where partners and data exist. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water bodies. Reaches are also defined on waterbodies and the approximate shorelines of the Great Lakes, the Atlantic and Pacific Oceans and the Gulf of Mexico. The NHD also incorporates the National Spatial Data Infrastructure framework criteria established by the Federal Geographic Data Committee.</abstract><purpose>The NHD is a national framework for assigning reach addresses to water-related entities, such as industrial discharges, drinking water supplies, fish habitat areas, wild and scenic rivers. Reach addresses establish the locations of these entities relative to one another within the NHD surface water drainage network, much like addresses on streets. Once linked to the NHD by their reach addresses, the upstream/downstream relationships of these water-related entities--and any associated information about them--can be analyzed using software tools ranging from spreadsheets to geographic information systems (GIS). GIS can also be used to combine NHD-based network analysis with other data layers, such as soils, land use and population, to help understand and display their respective effects upon one another. Furthermore, because the NHD provides a nationally consistent framework for addressing and analysis, water-related information linked to reach addresses by one organization (national, state, local) can be shared with other organizations and easily integrated into many different types of applications to the benefit of all.</purpose></descript><citation><citeinfo><origin>U.S. Geological Survey in cooperation with U.S. Environmental Protection Agency, USDA Forest Service, and other Federal, State and local partners (see dataset specific metadata under Data_Set_Credit for details).</origin><pubdate>See dataset specific metadata.</pubdate><title Sync="TRUE">NHDFlowline</title><ftname Sync="TRUE">NHDFlowline</ftname><geoform Sync="TRUE">vector digital data</geoform><onlink Sync="TRUE">\\igskbthisusy01\nhdgeo\oracle_export\GDBExtractServer\Template\NHD_File_Template_High_92v210.gdb</onlink><pubtime>Unknown</pubtime><pubinfo><pubplace>Reston, Virginia</pubplace><publish>U.S. Geological Survey</publish></pubinfo></citeinfo></citation><timeperd><current>See dataset specific metadata.</current><timeinfo><sngdate><caldate>REQUIRED: The year (and optionally month, or month and day) for which the data set corresponds to the ground.</caldate></sngdate></timeinfo></timeperd><status><progress>In work</progress><update>Irregular</update></status><spdom><bounding><westbc>-200</westbc><eastbc>-56.8344239</eastbc><northbc>143.165576</northbc><southbc>0</southbc></bounding></spdom><keywords><theme><themekt>U.S. Department of the Interior, U.S. Geological Survey, 1999, Standards for National Hydrography Dataset (http://mapping.usgs.gov/standards/)</themekt><themekey>FWHydrography</themekey><themekey>Hydrography</themekey><themekey>Stream / River</themekey><themekey>Lake / Pond</themekey><themekey>Canal / Ditch</themekey><themekey>Reservoir</themekey><themekey>Spring / Seep</themekey><themekey>Swamp / Marsh</themekey><themekey>Artificial Path</themekey><themekey>Reach Code</themekey></theme><place><placekey>US</placekey><placekt>U.S. Department of Commerce, 1977, Countries, dependencies, areas of special sovereignty, and their principal administrative divisions (Federal Information Processing Standards 10-3): Washington, D.C., National Institute of Standards and Technology.</placekt></place></keywords><accconst>None.</accconst><useconst>None.

that encodes information about naturally occurring and constructed bodies of water, paths through which water flows, and related entities. The information encoded about features includes a feature date, classification by type, other characteristics, a unique common identifier, the feature length or area, and (rarely) elevation of the surface of water pools and a description of the stage of the elevation. For reaches, encoded information includes a reach code. Names and their identifiers in the Geographic Names Information System, are assigned to most feature types. The direction of flow is encoded for networked features. The data also contains relations that encode metadata, and information that supports the exchange of future updates and improvements to the data. The names and definitions of all feature types, characteristics, and values are in the Standards for National Hydrography Dataset: Reston, Virginia, U.S. Geological Survey, 1999.

One or more of the following methods were used to test attribute accuracy: manual comparison of the source with hardcopy plots; symbolized display of the DLG on an interactive computer graphic system; selected attributes that could not be visually verified on plots or on screen were interactively queried and verified on screen. In addition, software validated feature types and characteristics against a master set of types and characteristics, checked that combinations of types and characteristics were valid, and that types and characteristics were valid for the delineation of the feature. Feature types, characteristics, and other attributes conform to the Standards for National Hydrography Dataset (USGS, 1999) as of the date they were loaded into the database. All names were validated against a current extract from the Geographic Names Information System (GNIS). The entry and identifier for the names match those in the GNIS. The association of each name to reaches has been interactively checked, however, operator error could in some cases apply a name to a wrong reach.
This statement is generally true for the most common sources of NHD data. Other sources and methods may have been used to create or update NHD data. In some cases, additional information may be found in the NHDMetadata table.</attraccr></attracc><logic>Points, nodes, lines, and areas conform to topological rules. Lines intersect only at nodes, and all nodes anchor the ends of lines. Lines do not overshoot or undershoot other lines where they are supposed to meet. There are no duplicate lines. Lines bound areas and lines identify the areas to the left and right of the lines. Gaps and overlaps among areas do not exist. All areas close.</logic><complete>The completeness of the data reflects the content of the sources, which most often are the published USGS topographic quadrangle and/or the USDA Forest Service Primary Base Series (PBS) map. The USGS topographic quadrangle is usually supplemented by Digital Orthophoto Quadrangles (DOQs). Features found on the ground may have been eliminated or generalized on the source map because of scale and legibility constraints. In general, streams longer than one mile (approximately 1.6 kilometers) were collected. Most streams that flow from a lake were collected regardless of their length. Only definite channels were collected so not all swamp/marsh features have stream/rivers delineated through them. Lake/ponds having an area greater than 6 acres were collected. Note, however, that these general rules were applied unevenly among maps during compilation. Reaches codes are defined on all features of type stream/river, canal/ditch, artificial path, coastline, and connector. Waterbody reach codes are defined on all lake/pond and most reservoir features. Names were applied from the GNIS database. Detailed capture conditions are provided for every feature type in the Standards for National Hydrography Dataset available online through http://mapping.usgs.gov/standards/.

These maps were compiled to meet National Map Accuracy Standards. For horizontal accuracy, this standard is met if at least 90 percent of points tested are within 0.02 inch (at map scale) of the true position. Additional offsets to positions may have been introduced where feature density is high to improve the legibility of map symbols. In addition, the digitizing of maps is estimated to contain a horizontal positional error of less than or equal to 0.003 inch standard error (at map scale) in the two component directions relative to the source maps. Visual comparison between the map graphic (including digital scans of the graphic) and plots or digital displays of points, lines, and areas, is used as control to assess the positional accuracy of digital data. Digital map elements along the adjoining edges of data sets are aligned if they are within a 0.02 inch tolerance (at map scale). Features with like dimensionality (for example, features that all are delineated with lines), with or without like characteristics, that are within the tolerance are aligned by moving the features equally to a common point. Features outside the tolerance are not moved; instead, a feature of type connector is added to join the features.

NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) Local resolution NHD is being developed where partners and data exist. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water bodies. Reaches are also defined on waterbodies and the approximate shorelines of the Great Lakes, the Atlantic and Pacific Oceans and the Gulf of Mexico. The NHD also incorporates the National Spatial Data Infrastructure framework criteria established by the Federal Geographic Data Committee.</abstract><purpose>The NHD is a national framework for assigning reach addresses to water-related entities, such as industrial discharges, drinking water supplies, fish habitat areas, wild and scenic rivers. Reach addresses establish the locations of these entities relative to one another within the NHD surface water drainage network, much like addresses on streets. Once linked to the NHD by their reach addresses, the upstream/downstream relationships of these water-related entities--and any associated information about them--can be analyzed using software tools ranging from spreadsheets to geographic information systems (GIS). GIS can also be used to combine NHD-based network analysis with other data layers, such as soils, land use and population, to help understand and display their respective effects upon one another. Furthermore, because the NHD provides a nationally consistent framework for addressing and analysis, water-related information linked to reach addresses by one organization (national, state, local) can be shared with other organizations and easily integrated into many different types of applications to the benefit of all.</purpose></descript><citation><citeinfo><origin>U.S. Geological Survey in cooperation with U.S. Environmental Protection Agency, USDA Forest Service, and other Federal, State and local partners (see dataset specific metadata under Data_Set_Credit for details).</origin><pubdate>See dataset specific metadata.</pubdate><title Sync="TRUE">NHDFlowline</title><ftname Sync="TRUE">NHDFlowline</ftname><geoform Sync="TRUE">vector digital data</geoform><onlink Sync="TRUE">\\igskbthisusy01\nhdgeo\oracle_export\GDBExtractServer\Template\NHD_File_Template_High_92v210.gdb</onlink><pubtime>Unknown</pubtime><pubinfo><pubplace>Reston, Virginia</pubplace><publish>U.S. Geological Survey</publish></pubinfo></citeinfo></citation><timeperd><current>See dataset specific metadata.</current><timeinfo><sngdate><caldate>REQUIRED: The year (and optionally month, or month and day) for which the data set corresponds to the ground.</caldate></sngdate></timeinfo></timeperd><status><progress>In work</progress><update>Irregular</update></status><spdom><bounding><westbc>-200</westbc><eastbc>-56.8344239</eastbc><northbc>143.165576</northbc><southbc>0</southbc></bounding></spdom><keywords><theme><themekt>U.S. Department of the Interior, U.S. Geological Survey, 1999, Standards for National Hydrography Dataset (http://mapping.usgs.gov/standards/)</themekt><themekey>FWHydrography</themekey><themekey>Hydrography</themekey><themekey>Stream / River</themekey><themekey>Lake / Pond</themekey><themekey>Canal / Ditch</themekey><themekey>Reservoir</themekey><themekey>Spring / Seep</themekey><themekey>Swamp / Marsh</themekey><themekey>Artificial Path</themekey><themekey>Reach Code</themekey></theme><place><placekey>US</placekey><placekt>U.S. Department of Commerce, 1977, Countries, dependencies, areas of special sovereignty, and their principal administrative divisions (Federal Information Processing Standards 10-3): Washington, D.C., National Institute of Standards and Technology.</placekt></place></keywords><accconst>None.</accconst><useconst>None.

that encodes information about naturally occurring and constructed bodies of water, paths through which water flows, and related entities. The information encoded about features includes a feature date, classification by type, other characteristics, a unique common identifier, the feature length or area, and (rarely) elevation of the surface of water pools and a description of the stage of the elevation. For reaches, encoded information includes a reach code. Names and their identifiers in the Geographic Names Information System, are assigned to most feature types. The direction of flow is encoded for networked features. The data also contains relations that encode metadata, and information that supports the exchange of future updates and improvements to the data. The names and definitions of all feature types, characteristics, and values are in the Standards for National Hydrography Dataset: Reston, Virginia, U.S. Geological Survey, 1999.

One or more of the following methods were used to test attribute accuracy: manual comparison of the source with hardcopy plots; symbolized display of the DLG on an interactive computer graphic system; selected attributes that could not be visually verified on plots or on screen were interactively queried and verified on screen. In addition, software validated feature types and characteristics against a master set of types and characteristics, checked that combinations of types and characteristics were valid, and that types and characteristics were valid for the delineation of the feature. Feature types, characteristics, and other attributes conform to the Standards for National Hydrography Dataset (USGS, 1999) as of the date they were loaded into the database. All names were validated against a current extract from the Geographic Names Information System (GNIS). The entry and identifier for the names match those in the GNIS. The association of each name to reaches has been interactively checked, however, operator error could in some cases apply a name to a wrong reach.
This statement is generally true for the most common sources of NHD data. Other sources and methods may have been used to create or update NHD data. In some cases, additional information may be found in the NHDMetadata table.</attraccr></attracc><logic>Points, nodes, lines, and areas conform to topological rules. Lines intersect only at nodes, and all nodes anchor the ends of lines. Lines do not overshoot or undershoot other lines where they are supposed to meet. There are no duplicate lines. Lines bound areas and lines identify the areas to the left and right of the lines. Gaps and overlaps among areas do not exist. All areas close.</logic><complete>The completeness of the data reflects the content of the sources, which most often are the published USGS topographic quadrangle and/or the USDA Forest Service Primary Base Series (PBS) map. The USGS topographic quadrangle is usually supplemented by Digital Orthophoto Quadrangles (DOQs). Features found on the ground may have been eliminated or generalized on the source map because of scale and legibility constraints. In general, streams longer than one mile (approximately 1.6 kilometers) were collected. Most streams that flow from a lake were collected regardless of their length. Only definite channels were collected so not all swamp/marsh features have stream/rivers delineated through them. Lake/ponds having an area greater than 6 acres were collected. Note, however, that these general rules were applied unevenly among maps during compilation. Reaches codes are defined on all features of type stream/river, canal/ditch, artificial path, coastline, and connector. Waterbody reach codes are defined on all lake/pond and most reservoir features. Names were applied from the GNIS database. Detailed capture conditions are provided for every feature type in the Standards for National Hydrography Dataset available online through http://mapping.usgs.gov/standards/.

In some cases, additional information may be found in the NHDMetadata table.</complete><posacc><horizpa><horizpar>Statements of horizontal positional accuracy are based on accuracy statements made for U.S. Geological Survey topographic quadrangle maps. These maps were compiled to meet National Map Accuracy Standards. For horizontal accuracy, this standard is met if at least 90 percent of points tested are within 0.02 inch (at map scale) of the true position. Additional offsets to positions may have been introduced where feature density is high to improve the legibility of map symbols. In addition, the digitizing of maps is estimated to contain a horizontal positional error of less than or equal to 0.003 inch standard error (at map scale) in the two component directions relative to the source maps. Visual comparison between the map graphic (including digital scans of the graphic) and plots or digital displays of points, lines, and areas, is used as control to assess the positional accuracy of digital data. Digital map elements along the adjoining edges of data sets are aligned if they are within a 0.02 inch tolerance (at map scale). Features with like dimensionality (for example, features that all are delineated with lines), with or without like characteristics, that are within the tolerance are aligned by moving the features equally to a common point. Features outside the tolerance are not moved; instead, a feature of type connector is added to join the features.

These maps were compiled to meet National Map Accuracy Standards. For vertical accuracy, this standard is met if at least 90 percent of well-defined points tested are within one-half contour interval of the correct value. Elevations of water surface printed on the published map meet this standard; the contour intervals of the maps vary. These elevations were transcribed into the digital data; the accuracy of this transcription was checked by visual comparison between the data and the map.

NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) Local resolution NHD is being developed where partners and data exist. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water bodies. Reaches are also defined on waterbodies and the approximate shorelines of the Great Lakes, the Atlantic and Pacific Oceans and the Gulf of Mexico. The NHD also incorporates the National Spatial Data Infrastructure framework criteria established by the Federal Geographic Data Committee.</abstract><purpose>The NHD is a national framework for assigning reach addresses to water-related entities, such as industrial discharges, drinking water supplies, fish habitat areas, wild and scenic rivers. Reach addresses establish the locations of these entities relative to one another within the NHD surface water drainage network, much like addresses on streets. Once linked to the NHD by their reach addresses, the upstream/downstream relationships of these water-related entities--and any associated information about them--can be analyzed using software tools ranging from spreadsheets to geographic information systems (GIS). GIS can also be used to combine NHD-based network analysis with other data layers, such as soils, land use and population, to help understand and display their respective effects upon one another. Furthermore, because the NHD provides a nationally consistent framework for addressing and analysis, water-related information linked to reach addresses by one organization (national, state, local) can be shared with other organizations and easily integrated into many different types of applications to the benefit of all.</purpose></descript><citation><citeinfo><origin>U.S. Geological Survey in cooperation with U.S. Environmental Protection Agency, USDA Forest Service, and other Federal, State and local partners (see dataset specific metadata under Data_Set_Credit for details).</origin><pubdate>See dataset specific metadata.</pubdate><title Sync="TRUE">NHDFlowline</title><ftname Sync="TRUE">NHDFlowline</ftname><geoform Sync="TRUE">vector digital data</geoform><onlink Sync="TRUE">\\igskbthisusy01\nhdgeo\oracle_export\GDBExtractServer\Template\NHD_File_Template_High_92v210.gdb</onlink><pubtime>Unknown</pubtime><pubinfo><pubplace>Reston, Virginia</pubplace><publish>U.S. Geological Survey</publish></pubinfo></citeinfo></citation><timeperd><current>See dataset specific metadata.</current><timeinfo><sngdate><caldate>REQUIRED: The year (and optionally month, or month and day) for which the data set corresponds to the ground.</caldate></sngdate></timeinfo></timeperd><status><progress>In work</progress><update>Irregular</update></status><spdom><bounding><westbc>-200</westbc><eastbc>-56.8344239</eastbc><northbc>143.165576</northbc><southbc>0</southbc></bounding></spdom><keywords><theme><themekt>U.S. Department of the Interior, U.S. Geological Survey, 1999, Standards for National Hydrography Dataset (http://mapping.usgs.gov/standards/)</themekt><themekey>FWHydrography</themekey><themekey>Hydrography</themekey><themekey>Stream / River</themekey><themekey>Lake / Pond</themekey><themekey>Canal / Ditch</themekey><themekey>Reservoir</themekey><themekey>Spring / Seep</themekey><themekey>Swamp / Marsh</themekey><themekey>Artificial Path</themekey><themekey>Reach Code</themekey></theme><place><placekey>US</placekey><placekt>U.S. Department of Commerce, 1977, Countries, dependencies, areas of special sovereignty, and their principal administrative divisions (Federal Information Processing Standards 10-3): Washington, D.C., National Institute of Standards and Technology.</placekt></place></keywords><accconst>None.</accconst><useconst>None.

that encodes information about naturally occurring and constructed bodies of water, paths through which water flows, and related entities. The information encoded about features includes a feature date, classification by type, other characteristics, a unique common identifier, the feature length or area, and (rarely) elevation of the surface of water pools and a description of the stage of the elevation. For reaches, encoded information includes a reach code. Names and their identifiers in the Geographic Names Information System, are assigned to most feature types. The direction of flow is encoded for networked features. The data also contains relations that encode metadata, and information that supports the exchange of future updates and improvements to the data. The names and definitions of all feature types, characteristics, and values are in the Standards for National Hydrography Dataset: Reston, Virginia, U.S. Geological Survey, 1999.

One or more of the following methods were used to test attribute accuracy: manual comparison of the source with hardcopy plots; symbolized display of the DLG on an interactive computer graphic system; selected attributes that could not be visually verified on plots or on screen were interactively queried and verified on screen. In addition, software validated feature types and characteristics against a master set of types and characteristics, checked that combinations of types and characteristics were valid, and that types and characteristics were valid for the delineation of the feature. Feature types, characteristics, and other attributes conform to the Standards for National Hydrography Dataset (USGS, 1999) as of the date they were loaded into the database. All names were validated against a current extract from the Geographic Names Information System (GNIS). The entry and identifier for the names match those in the GNIS. The association of each name to reaches has been interactively checked, however, operator error could in some cases apply a name to a wrong reach.
This statement is generally true for the most common sources of NHD data. Other sources and methods may have been used to create or update NHD data. In some cases, additional information may be found in the NHDMetadata table.</attraccr></attracc><logic>Points, nodes, lines, and areas conform to topological rules. Lines intersect only at nodes, and all nodes anchor the ends of lines. Lines do not overshoot or undershoot other lines where they are supposed to meet. There are no duplicate lines. Lines bound areas and lines identify the areas to the left and right of the lines. Gaps and overlaps among areas do not exist. All areas close.</logic><complete>The completeness of the data reflects the content of the sources, which most often are the published USGS topographic quadrangle and/or the USDA Forest Service Primary Base Series (PBS) map. The USGS topographic quadrangle is usually supplemented by Digital Orthophoto Quadrangles (DOQs). Features found on the ground may have been eliminated or generalized on the source map because of scale and legibility constraints. In general, streams longer than one mile (approximately 1.6 kilometers) were collected. Most streams that flow from a lake were collected regardless of their length. Only definite channels were collected so not all swamp/marsh features have stream/rivers delineated through them. Lake/ponds having an area greater than 6 acres were collected. Note, however, that these general rules were applied unevenly among maps during compilation. Reaches codes are defined on all features of type stream/river, canal/ditch, artificial path, coastline, and connector. Waterbody reach codes are defined on all lake/pond and most reservoir features. Names were applied from the GNIS database. Detailed capture conditions are provided for every feature type in the Standards for National Hydrography Dataset available online through http://mapping.usgs.gov/standards/.

These maps were compiled to meet National Map Accuracy Standards. For horizontal accuracy, this standard is met if at least 90 percent of points tested are within 0.02 inch (at map scale) of the true position. Additional offsets to positions may have been introduced where feature density is high to improve the legibility of map symbols. In addition, the digitizing of maps is estimated to contain a horizontal positional error of less than or equal to 0.003 inch standard error (at map scale) in the two component directions relative to the source maps. Visual comparison between the map graphic (including digital scans of the graphic) and plots or digital displays of points, lines, and areas, is used as control to assess the positional accuracy of digital data. Digital map elements along the adjoining edges of data sets are aligned if they are within a 0.02 inch tolerance (at map scale). Features with like dimensionality (for example, features that all are delineated with lines), with or without like characteristics, that are within the tolerance are aligned by moving the features equally to a common point. Features outside the tolerance are not moved; instead, a feature of type connector is added to join the features.

NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) Local resolution NHD is being developed where partners and data exist. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water bodies. Reaches are also defined on waterbodies and the approximate shorelines of the Great Lakes, the Atlantic and Pacific Oceans and the Gulf of Mexico. The NHD also incorporates the National Spatial Data Infrastructure framework criteria established by the Federal Geographic Data Committee.</abstract><purpose>The NHD is a national framework for assigning reach addresses to water-related entities, such as industrial discharges, drinking water supplies, fish habitat areas, wild and scenic rivers. Reach addresses establish the locations of these entities relative to one another within the NHD surface water drainage network, much like addresses on streets. Once linked to the NHD by their reach addresses, the upstream/downstream relationships of these water-related entities--and any associated information about them--can be analyzed using software tools ranging from spreadsheets to geographic information systems (GIS). GIS can also be used to combine NHD-based network analysis with other data layers, such as soils, land use and population, to help understand and display their respective effects upon one another. Furthermore, because the NHD provides a nationally consistent framework for addressing and analysis, water-related information linked to reach addresses by one organization (national, state, local) can be shared with other organizations and easily integrated into many different types of applications to the benefit of all.</purpose></descript><citation><citeinfo><origin>U.S. Geological Survey in cooperation with U.S. Environmental Protection Agency, USDA Forest Service, and other Federal, State and local partners (see dataset specific metadata under Data_Set_Credit for details).</origin><pubdate>See dataset specific metadata.</pubdate><title Sync="TRUE">NHDFlowline</title><ftname Sync="TRUE">NHDFlowline</ftname><geoform Sync="TRUE">vector digital data</geoform><onlink Sync="TRUE">\\igskbthisusy01\nhdgeo\oracle_export\GDBExtractServer\Template\NHD_File_Template_High_92v210.gdb</onlink><pubtime>Unknown</pubtime><pubinfo><pubplace>Reston, Virginia</pubplace><publish>U.S. Geological Survey</publish></pubinfo></citeinfo></citation><timeperd><current>See dataset specific metadata.</current><timeinfo><sngdate><caldate>REQUIRED: The year (and optionally month, or month and day) for which the data set corresponds to the ground.</caldate></sngdate></timeinfo></timeperd><status><progress>In work</progress><update>Irregular</update></status><spdom><bounding><westbc>-200</westbc><eastbc>-56.8344239</eastbc><northbc>143.165576</northbc><southbc>0</southbc></bounding></spdom><keywords><theme><themekt>U.S. Department of the Interior, U.S. Geological Survey, 1999, Standards for National Hydrography Dataset (http://mapping.usgs.gov/standards/)</themekt><themekey>FWHydrography</themekey><themekey>Hydrography</themekey><themekey>Stream / River</themekey><themekey>Lake / Pond</themekey><themekey>Canal / Ditch</themekey><themekey>Reservoir</themekey><themekey>Spring / Seep</themekey><themekey>Swamp / Marsh</themekey><themekey>Artificial Path</themekey><themekey>Reach Code</themekey></theme><place><placekey>US</placekey><placekt>U.S. Department of Commerce, 1977, Countries, dependencies, areas of special sovereignty, and their principal administrative divisions (Federal Information Processing Standards 10-3): Washington, D.C., National Institute of Standards and Technology.</placekt></place></keywords><accconst>None.</accconst><useconst>None.

that encodes information about naturally occurring and constructed bodies of water, paths through which water flows, and related entities. The information encoded about features includes a feature date, classification by type, other characteristics, a unique common identifier, the feature length or area, and (rarely) elevation of the surface of water pools and a description of the stage of the elevation. For reaches, encoded information includes a reach code. Names and their identifiers in the Geographic Names Information System, are assigned to most feature types. The direction of flow is encoded for networked features. The data also contains relations that encode metadata, and information that supports the exchange of future updates and improvements to the data. The names and definitions of all feature types, characteristics, and values are in the Standards for National Hydrography Dataset: Reston, Virginia, U.S. Geological Survey, 1999.

One or more of the following methods were used to test attribute accuracy: manual comparison of the source with hardcopy plots; symbolized display of the DLG on an interactive computer graphic system; selected attributes that could not be visually verified on plots or on screen were interactively queried and verified on screen. In addition, software validated feature types and characteristics against a master set of types and characteristics, checked that combinations of types and characteristics were valid, and that types and characteristics were valid for the delineation of the feature. Feature types, characteristics, and other attributes conform to the Standards for National Hydrography Dataset (USGS, 1999) as of the date they were loaded into the database. All names were validated against a current extract from the Geographic Names Information System (GNIS). The entry and identifier for the names match those in the GNIS. The association of each name to reaches has been interactively checked, however, operator error could in some cases apply a name to a wrong reach.
This statement is generally true for the most common sources of NHD data. Other sources and methods may have been used to create or update NHD data. In some cases, additional information may be found in the NHDMetadata table.</attraccr></attracc><logic>Points, nodes, lines, and areas conform to topological rules. Lines intersect only at nodes, and all nodes anchor the ends of lines. Lines do not overshoot or undershoot other lines where they are supposed to meet. There are no duplicate lines. Lines bound areas and lines identify the areas to the left and right of the lines. Gaps and overlaps among areas do not exist. All areas close.</logic><complete>The completeness of the data reflects the content of the sources, which most often are the published USGS topographic quadrangle and/or the USDA Forest Service Primary Base Series (PBS) map. The USGS topographic quadrangle is usually supplemented by Digital Orthophoto Quadrangles (DOQs). Features found on the ground may have been eliminated or generalized on the source map because of scale and legibility constraints. In general, streams longer than one mile (approximately 1.6 kilometers) were collected. Most streams that flow from a lake were collected regardless of their length. Only definite channels were collected so not all swamp/marsh features have stream/rivers delineated through them. Lake/ponds having an area greater than 6 acres were collected. Note, however, that these general rules were applied unevenly among maps during compilation. Reaches codes are defined on all features of type stream/river, canal/ditch, artificial path, coastline, and connector. Waterbody reach codes are defined on all lake/pond and most reservoir features. Names were applied from the GNIS database. Detailed capture conditions are provided for every feature type in the Standards for National Hydrography Dataset available online through http://mapping.usgs.gov/standards/.

In some cases, additional information may be found in the NHDMetadata table.</complete><posacc><horizpa><horizpar>Statements of horizontal positional accuracy are based on accuracy statements made for U.S. Geological Survey topographic quadrangle maps. These maps were compiled to meet National Map Accuracy Standards. For horizontal accuracy, this standard is met if at least 90 percent of points tested are within 0.02 inch (at map scale) of the true position. Additional offsets to positions may have been introduced where feature density is high to improve the legibility of map symbols. In addition, the digitizing of maps is estimated to contain a horizontal positional error of less than or equal to 0.003 inch standard error (at map scale) in the two component directions relative to the source maps. Visual comparison between the map graphic (including digital scans of the graphic) and plots or digital displays of points, lines, and areas, is used as control to assess the positional accuracy of digital data. Digital map elements along the adjoining edges of data sets are aligned if they are within a 0.02 inch tolerance (at map scale). Features with like dimensionality (for example, features that all are delineated with lines), with or without like characteristics, that are within the tolerance are aligned by moving the features equally to a common point. Features outside the tolerance are not moved; instead, a feature of type connector is added to join the features.

These maps were compiled to meet National Map Accuracy Standards. For vertical accuracy, this standard is met if at least 90 percent of well-defined points tested are within one-half contour interval of the correct value. Elevations of water surface printed on the published map meet this standard; the contour intervals of the maps vary. These elevations were transcribed into the digital data; the accuracy of this transcription was checked by visual comparison between the data and the map.

<descript>
<abstract>The 2013 cartographic boundary shapefiles are simplified representations of selected
geographic areas from the U.S. Census Bureau's Master Address File / Topologically
Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). These boundary
files are specifically designed for small-scale thematic mapping. When possible
generalization is performed with the intent to maintain the hierarchical relationships among
geographies and to maintain the alignment of geographies within a file set for a given year.
Geographic areas may not align with the same areas from another year. Some geographies are
available as nation-based shapefiles while others are available only as state-based
files.</abstract>
<purpose>These files were specifically created to support small-scale thematic mapping. To
improve the appearance of shapes at small scales, areas are represented with fewer vertices
than detailed TIGER/Line Shapefiles. Cartographic boundary files take up less disk space
than their ungeneralized counterparts. Cartographic boundary files take less time to render
on screen than TIGER/Line Shapefiles. You can join this shapefile with table data downloaded
from American FactFinder by using the AFFGEOID field in the cartographic boundary file. If
detailed boundaries are required, please use the TIGER/Line Shapefiles instead of the
generalized cartographic boundary files. </purpose>

<useconst>The intended display scale for this file is 1:500,000. This file should not be
displayed at scales larger than 1:500,000. These products are free to use in a product or
publication, however acknowledgement must be given to the U.S. Census Bureau as the source.
The boundary information is for visual display at appropriate small scales only.
Cartographic boundary files should not be used for geographic analysis including area or
perimeter calculation. Files should not be used for geocoding addresses. Files should not be
used for determining precise geographic area relationships.</useconst>

<attracc>
<attraccr>Accurate against American National Standards Institute (ANSI)
Publication INCITS 446-2008 (Geographic Names Information System (GNIS)) at the 100% level for the codes and base names present in the file. The remaining attribute information has
been examined but has not been fully tested for accuracy.</attraccr>
</attracc>
<logic>The Census Bureau performed automated tests to ensure logical
consistency of the source database. Segments making up the outer and inner boundaries of a
polygon tie end-to-end to completely enclose the area. All polygons were tested for closure.
The Census Bureau uses its internally developed geographic update system to enhance and
modify spatial and attribute data in the Census MAF/TIGER database. Standard geographic
codes, such as FIPS codes for states, counties, municipalities, county subdivisions, places,
American Indian/Alaska Native/Native Hawaiian areas, and congressional districts are used
when encoding spatial entities. The Census Bureau performed spatial data tests for logical
consistency of the codes during the compilation of the original Census MAF/TIGER database
files. Feature attribute information has been examined but has not been fully tested for
consistency. For the cartographic boundary shapefiles, the Point and Vector Object Count for
the G-polygon SDTS Point and Vector Object Type reflects the number of records in the
shapefile attribute table. For multi-polygon features, only one attribute record exists for
each multi-polygon rather than one attribute record per individual G-polygon component of
the multi-polygon feature. TIGER/Line Shapefile multi-polygons are an exception to the
G-polygon object type classification. Therefore, when multi-polygons exist in a shapefile,
the object count will be less than the actual number of
G-polygons.</logic>
<complete>The cartographic boundary files are generalized representations of extracts
taken from the MAF/TIGER Database. Generalized boundary files are clipped to a simplified
version of the U.S. outline. As a result, some off-shore areas may be excluded from the
generalized files. Some small holes or discontiguous parts of areas are not included in
generalized files.</complete>
