The Geographic Names Information System (GNIS) is the Federal standard for geographic nomenclature. The U.S. Geological Survey developed the GNIS for the U.S. Board on Geographic Names, a Federal inter-agency body chartered by public law to maintain uniform feature name usage throughout the Government and to promulgate standard names to the public. The GNIS is the official repository of domestic geographic names data; the official vehicle for geographic names use by all departments of the Federal Government; and the source for applying geographic names to Federal electronic and printed products of all types. See http://geonames.usgs.gov for additional information.
The Geographic Names Information System contains information about physical and cultural geographic features of all types in the United States, associated areas, and Antarctica, current and historical, but not including roads and highways. The database holds the Federally recognized name of each feature and defines the feature location by state, county, USGS topographic map, and geographic coordinates. Other attributes include names or spellings other than the official name, feature designations, feature classification, historical and descriptive information, and for some categories the geometric boundaries. The database assigns a unique, permanent feature identifier, the Feature ID, as a standard Federal key for accessing, integrating, or reconciling feature data from multiple data sets. The GNIS collects data from a broad program of partnerships with Federal, State, and local government agencies and other authorized contributors. The GNIS provides data to all levels of government and to the public, as well as to numerous applications through a web query site, web map and feature services, file download services, and customized files upon request.
The U.S. Board on Geographic Names was created in 1890 and established in its present form by Public Law in 1947 to establish and maintain uniform geographic name usage throughout the Federal Government. The Board serves all government agencies and the public as the central authority to which name inquiries, name issues, and new name proposals can be directed. It is comprised of representatives of Federal agencies associated with land management and cartography. Sharing its responsibilities with the Secretary of the Interior, the Board develops principles, policies, and procedures governing the use of both domestic and foreign geographic names as well as undersea and Antarctic feature names.

The Geographic Names Information System was developed by the U.S. Geological Survey in cooperation with the U.S. Board on Geographic Names.
The Geographic Names Information System is resident on a Sun database server and a Sun web server with Sun Solaris operating system. The database is an Oracle RDBMS with Oracle Spatial. The web server is Oracle Internet Application Server. Web map layers are served through ESRI Spatial Data Engine (SDE) and an ESRI ArcIMS map service. The system contains approximately 2 million records, averaging 500 bytes in length.

The National Map
The National Map, is a seamless, continuously maintained set of public domain geographic base information that serves as a foundation for integrating, sharing, and using other data easily and consistently. The National Map viewer is a Web-enabled portal to all of the geospatial information contained in The National Map. This portal not only supports on-line access to the geospatial information, but also allows the download of digital data and creation of cartographic products. The GNIS supports The National Map as the source for the gazetteer search in Find Place function of The National Map viewer and as active names layers.

The National Atlas
The National Atlas summarizes national-scale geographical information and delivers easy to use, map-like views of America's natural and sociocultural landscapes. This digital version revises a large bound collection of paper maps that was published in 1970. The Atlas serves a diverse populace as an essential reference, a framework for information discovery, an instrument of education, an aid in research, and a reliable source of government information. It includes stimulating products and services for children and adults to understand complex relationships among environments, places, and people. It contributes to our knowledge of the environmental, resource, demographic, economic, social, political, and historical dimensions of American life. Though it cannot display detailed map information, the Atlas directs users to other sources for this information. The GNIS provides geographic feature, location, and attribute data to the National Atlas.

The National Hydrography Dataset
The National Hydrography Dataset (NHD) is a comprehensive set of digital spatial data that contains information about surface water features such as lakes, ponds, streams, rivers, springs and wells. Within the NHD, surface water features are combined to form "reaches," which provide the framework for linking water-related data to the NHD surface water drainage network. These linkages enable the analysis and display of these water-related data in upstream and downstream order. The GNIS provides geographic feature name data to the National Hydrography Dataset.

LandView
LandView is a desktop mapping system that searches and maps selected information from the Environmental Protection Agency, the Census Bureau, and the U.S. Geological Survey. LandView contains a large subset of GNIS feature, location, and attribute data for the United States. It is available on DVD. See the LandView web site for information concerning the latest edition and ordering.
http://landview.census.gov/
During Phase I data compilation, a random sample of 10% of the entries in the system were visually verified against the compilation source data (large-scale USGS topographic maps) to ensure an accuracy rate of at least 95%. Subsequent data compilation and input processes ensure accuracy with programmed validation checks for format and content, visual examination, and spot checks of data.
During Phase I data compilation, a random sample of 10% of the entries in the system were visually verified against the compilation source data (large-scale USGS topographic maps) to ensure logical consistency of locative references (geographic coordinates, topographic map, and county. Subsequent data compilation and input processes include programmed validation checks for logical consistency, visual examination, and spot checks of data.
This dataset contains information about United States physical and cultural geographic features of all types and classes, with the exception of most roads and highways. Subsequent to the original data compilation process, which was taken primarily from Federal maps, the GNIS has become dependent on input from Federal, State, county, and local government agencies and other approved sources. The completeness, currency, and accuracy of the data varies by area depending on the quality and timeliness of that input. Accordingly, the Geographic Names Project actively seeks to expand partnerships with Government agencies at all levels and other interested organizations. The latest tools and methodologies are being applied, including web map and feature services, and joint or linked web applications, to ensure that local data are properly represented in the GNIS and through the GNIS to all Federal agencies and to the public. Feature additions or corrections are accepted for consideration from any source, and when validated by appropriate agencies, will be entered into the database. Local and State agencies are encouraged to submit data and to participate in the GNIS partnership program. Non-government organizations with valuable data are considered on a case basis. Authorized partners have access to web based transaction entry and edit forms, which submit data directly to the GNIS for review and inclusion in the database. Partners also submit batch files in most standard formats, and coordinate with the Geographic Names Project to develop joint services, processes, and applications for greatest efficiency. Data entered into the GNIS immediately is available to all web services and applications dependent on it. For additional information or to request user accounts for entry and edit of production data and web seminar training, contact gnis_manager@usgs.gov.
Accuracy of these digital data is based upon the use of printed or electronic source graphics which are compiled to meet National Map Accuracy Standards. Comparison to the graphic source is used as control to assess digital positional accuracy.

Geographic feature
A geographic feature is any relatively permanent part of the natural or manmade landscape or seascape that has recognizable identity within a particular cultural context. The primary attributes of a geographic feature are name and location.
Principles, Policies, and Procedures: Domestic Geographic Names, By Donald J. Orth, Executive Secretary, Domestic Geographic Names (emeritus) and Roger L. Payne, Executive Secretary, United States Board on Geographic Names and Domestic Geographic Names, Third printing (revised) and Preliminary Online Edition, 1997 (http://geonames.usgs.gov/docs/pro_pol_pro.pdf).
Feature Identifier
A permanent, unique number assigned to a geographic feature for the sole purpose of uniquely identifying that feature as a record in any information system database, dataset, file, or document and for distinguishing it from all other feature records so identified. The number is assigned sequentially (highest existing number plus one) to new records as they are created in the Geographic Names Information System. The number, by design, carries no information or association to the content of the feature record and therefore is not subject to change as attribute values change. Once assigned to a feature, the number is never changed or withdrawn, and never reassigned. The Feature ID can be applied in conjunction with system-unique record identifiers in any database or system, thus providing a national standard common reference identifier across multiple datasets. The Feature ID is stored in the GNIS database as an integer with a maximum of ten digits.

Feature Name
A geographic feature name and its written form and application approved or recognized as official by the United States Board on Geographic Names for use throughout the Federal Government. The official name is established either by policy or by decision of the Board on Geographic Names. It is the proper name, specific term, or expression by which a particular geographic entity is, or was, known. A geographic feature may have only one official name, which must be the name applied to the feature on all Federal products, electronic or printed.

Feature Variant Name
A variant name is a current or historical name or spelling for a geographic feature other than its official name determined by an authoritative source to be useful for reference to, identification of, or location of a geographic feature, and which is supported by documentary or physical evidence or references as defined in the Names Data Users Guide. A geographic feature may have any number of variant names.

Primary Point
The official feature location is a single point to which the official feature name is associated in order to ensure positive and unique identification and association, also referred to as the primary point. The location is determined by the authoritative source and is approved or recognized as official by the U.S. Board on Geographic Names by decision or by policy delegation to the authoritative source. The placing of the location point is governed by policies of the Board as defined in the Names Data Users Guide and GNIS metadata, generally at or near the geographic center, but there are exceptions for certain classes of features. For example, the official feature location of flowing bodies of water (streams, rivers, creeks, etc.) or trending linear features (valleys, gulchs, gullys, hollows, etc.) is at the mouth. A geographic feature may have only one official location regardless of size, extent, composition, structure, or boundaries. The location point is coincident with, but in addition to and independent of, any other geospatial representation or boundary definition that may be attached to the feature in other datasets. Linear and aerial features may have secondary points as defined in the Names Data Users Guide and GNIS metadata. Locations are stored in the Geographic Names Information System as latitude and longitude in decimal degrees to seven places, North American Datum 1983 (NAD83), and are available in geospatial format as needed. (Note: Records showing all zeros for latitude and longitude indicate that the coordinates of the feature are unknown. They are recorded in the database as zeros to satisfy the format requirements of a numerical data type. They are not errors and do not reference the actual geographic coordinates at 0 latitude, 0 longitude.)

Secondary Point
The latitude and longitude of a point locating a linear or areal geographic feature on a map of the USGS National Base Map series (at a scale of 1:24000 or 1:25000) other than the map containing the primary point. With one exception (i.e., the point representing the source of a stream, valley or arroyo may be on the same map as the primary point) a feature is assigned one point per map on which it is located. The points are sequenced. Sequence number one is always the primary point and the remaining points are secondary points. For a linear feature with feature class equal to valley, stream, or arroyo, the points are sequenced from mouth toward the source and the highest sequence number is the source. For other linear features and for areal features, secondary points are sequenced according to guidelines of the U.S. Board On Geographic Names. The location of the point on the feature within the map is arbitrary. This method of associating features with maps was conceived prior to geographic information system technology and has been retained as a useful approximation of feature extent and a reference to printed maps. These points do not represent boundaries or geometries and should not be confused with them. Secondary points are stored in the Geographic Names Information System as latitude and longitude in decimal degrees to seven places, North American Datum 1983 (NAD83), and are available in geospatial format as needed. (Note: Records showing all zeros for latitude and longitude indicate that the coordinates of the feature are unknown. They are recorded in the database as zeros to satisfy the format requirements of a numerical data type. They are not errors and do not reference the actual geographic coordinates at 0 latitude, 0 longitude.)

Feature Class
A feature class is a designation for a group of features in a broadly defined descriptive category. All features are assigned to one and only one class. They do not individually classify all kinds of cultural and natural features. By design, there are no Federal or industry standards or guidelines for feature classification. These classifications originally were developed for mainframe file structure search purposes. Although the terms are generally consistent with dictionary definitions, they may not conform exactly and are not always intuitive.

Geographic Names Project, USGS, 523 National Center, Reston, VA 20192-0523 (gnis_manager@usgs.gov).
Feature Designation
A feature designation is assigned to a feature or group of features to define further and classify feature functions, purpose, and attributes. For example, a feature designated historical is one that once existed but has ceased to exist, is no longer apparent on the landscape, and/or no longer serves its original purpose. Other examples include State Capitol, County Seat, Independent City, and Subdivision. A feature may have more than one designation. Designations and their definitions will be added as needed.

Elevation
The elevation above sea level of the feature at the primary point (positive number) or depth of a feature at the lowest point below sea level (negative number). By default, elevations are provided in meters. For custom data extracts, elevations can be provided in either feet or meters depending on user requirements. Elevation figures are not official and do not represent precisely measured or surveyed values. The data are extracted from the National Elevation Dataset (http://ned.usgs.gov/) for the primary coordinates and may differ from elevations cited in other sources. The differences will be most evident for features such as summits where precision is of more concern and where the local relief (rate of change of elevation) may be more prominent. However, the elevation figures are within tolerances for the data for most points and sufficiently accurate for purposes of general information.

Census Code
Originally the "Place Code," a five-digit feature record identifier in the Federal Information Processing Standard (FIPS) 55 database, but now used only for internal purposes by the Census Bureau and renamed for clarity. To be unique, the Census Code must be preceded by the two-digit State code. The FIPS55 database and data were merged with the Geographic Names Information System. The GNIS Feature ID superseded the Census (Place) Code as the Federal standard unique, permanent, feature identifier and will over time replace it in all Federal systems. Census Codes are retained in the GNIS during the transition, and are viewable and downloadable from the GNIS public web site.

It is maintained in the GNIS through collaboration with the Census Bureau and provided through the GNIS products and services for the convenience of other systems that still use it. This code is not otherwise used or referenced in the GNIS.

GSA Code
General Services Administration (GSA) location code. Maintained by GSA as a place reference for administrative and personnel purposes. It is maintained in the GNIS through collaboration with the GSA and provided in GNIS products and services for convenience of users. Not otherwise used or referenced by the GNIS. The code is four digits in fixed-length format with leading zeros. The code is only unique within states and therefore may be preceded by the two digit numeric state code to achieve uniqueness.

Primary attributes are available from the names layers served through an ESRI ArcGIS web map service. The following are instructions for access by ESRI ArcMap. For other tools, please adjust accordingly. 1) Click Add Data, 2) expand drop-down to GIS Servers, 3) select Add WMS Server, 4) enter the following full URL, 5) click Get Layers, then click OK, (The service is added to the list of available servers), 6) select service if not already highlighted, 7) click Add, 8) select the service again in pop up box, 9) click Add. The layers should appear in the ArcMap table of contents. No data will appear until you zoom in far enough over continental the US. The layers display at varying resolutions. See these same layers in The National Map viewer under the Names category in the layer list. The names layers do not include all attributes. Customized files of large data sets also can be provided on request in most standard formats including shape files. The data is presented in format Arc SDE.

XML
Primary attributes are available from the GNIS XML service. Instructions: Insert desired parameter value(s) in single quotes following the equals sign. Do not change or delete unused parameters. Parameter definitions: fname = feature name. (Exact match. Not case sensitive.) state = state name. (Exact match. Case sensitive.) cnty = county name. (Exact match. Not case sensitive.) cell = USGS standard topographic map name. (Exact match. Not case sensitive.) ftype = feature type (class). See the GNIS public query page (http://geonames.usgs.gov/pls/gnispublic/). The pick list for feature class contains the values. Note that the value (populated place) in the pick list is abbreviated (ppl) in the data. See question 14, How can I acquire GNIS data?, of our FAQ (http://geonames.usgs.gov/domestic/faqs.htm) for more details and sample URLs. As currently implemented, it is for relatively small data set queries not for mass downloads. It does not include all attributes. Customized files of large data sets also can be provided on request in most standard formats. The data is presented in format XML.
