18、I INCITS 446-2008.)The United States Board on Geographic NamesThe United States Board on Geographic Names (http:/geonames.usgs.gov/) is afederal body created in 1890 to maintain standardized geographic feature name andlocation usage throughout the federal government. The Board comprises representa-t

19、ives of federal departments and independent agencies concerned with geographicinformation, population, ecology, and management of public lands. Sharing its re-sponsibilities with the Secretary of the Interior, the Board promulgates official geo-graphic feature names with locative attributes as well

20、as principles, policies, andprocedures governing the data. An underlying principle of the Board is formal recog-nition of present day local usage or preferences. The U.S. Geological Survey (USGS)Geographic Names Project is the executive agent and supporting agency for theBoard.By law, the Board is r

21、esponsible for all geographic names except those applying tooffices or establishments of federal agencies. Practically, however, the Board de-cides primarily on the names of natural features of the land, reservoirs, and canals inthe United States, its territories, and outlying areas. Unless asked to

22、 do so, the Boarddoes not rule on the names of cultural features such as roads, streets, shopping cen-ters, churches, schools, hospitals, and airports. Borderline cases exist; for example,the Board determines the official names of reservoirs not formally named by Con-gress, but not the names of dams

23、 that form the reservoirs.The original program of names standardization (not regulation) began during thesurge of exploration, mining, and settlement of western territories after the Civil War.Inconsistencies and contradictions among numerous feature names, spellings, andlocations became a serious p

24、roblem to surveyors, map makers, and scientists whorequired uniform, non-conflicting geographic nomenclature. President Harrisonsigned an executive order establishing the Board and giving it authority to resolvethese critical questions. Decisions of the Board were accepted as binding by all de-partm

25、ents and agencies of the federal government.Congress recreated the Board in 1947 by Public Law 80-242. In partnership with fed-eral, state, and local agencies and state names authorities, the Board serves as acentral authority to which feature name and location inquiries, issues, changes, andproposa

26、ls may be directed. The usefulness of this type of program has been proven time and again, and todaymore than fifty nations have some type of national names authority. The United Na-tions stated: “the best method to achieve international standardization is throughstrong programs of national standard

27、ization.“ Numerous nations established policiesrelevant to the toponymic (the study of names) issues in their respective countries.The Geographic Names Information System (GNIS)In the mid-1970s, the Geographic Names Information System (GNIS) was developedas an essential application of information te

28、chnology to the mission of the Board. TheBoard designated the GNIS as the official repository of domestic geographic featurenames and locations data, the official vehicle for use of these data by all departmentsof the federal government, and the source for applying these data to federal electron-ic

29、and printed products. The GNIS is the federal standard for geographic nomencla-ture.The GNIS contains information about selected domestic physical and cultural geo-graphic features of importance and interest to users of geographic information sys-tem data. The database holds the federally recognized

30、 name of each feature andCopyright American National Standards Institute Provided by IHS under license with ANSI Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-iiidefines the feature location by state, county, USGS topographic map, and geograph-ic coordinates. Oth

31、er attributes include names or spellings other than the officialname, feature designations, feature classification, and historical and descriptive in-formation. The database assigns a unique, permanent feature record identifier as thestandard federal key for accessing, integrating, and reconciling f

32、eature data acrossmultiple data sets.The GNIS contains data compiled over thirty years. In the first phase (1976-1981),data were entered from the largest-scale USGS topographic maps available, ForestService maps and visitor maps, and National Ocean Service charts, and compared tothe records of the U

33、.S. Board on Geographic Names going back to 1890. Analysisdetermined that these sources provided less than twenty percent of the names forextant features. Phase II commenced in 1982 as a thirty year program to collect databy contract from official state, local, and other approved sources including h

34、istoricalmaps and documents. All but one state (Alaska) are in process or have been com-pleted.The third and ongoing phase for maintenance commenced in 1985. The GNIS nowoperates through a broad and growing program of partnerships with federal, state,and local government agencies. Partners submit ne

35、w and revised feature records inconjunction with their mapping and geographical information system data mainte-nance programs. The objective is to integrate and synchronize GNIS feature names,locations, and other attributes with state and local holdings, and therefore ensureproper representation of

36、local data at the federal and national level.The GNIS utilizes web, database, and GIS technology to automate and simplifymaintenance, ensure data consistency, integrity, and accuracy, and to continuemeeting the requirements of the Board for standardization. Data are available to alllevels of governm

37、ent, to the public, and to numerous applications through a web que-ry site (http:/geonames.usgs.gov/pls/gnispublic/), web map and feature services, filedownload services, and customized files upon request. A web-based data entry andedit application allows partners to submit transactions directly for

38、 validation and entryinto the database, where changes immediately become available to web servicesand applications. Batch files also are accepted in most standard formats. The GNIS is an element of The National Map, the National Spatial Data Infrastruc-ture, and the Department of Homeland Security (

39、DHS) Geospatial Data Model. Forover a century, the Board on Geographic Names and the Geographic Names Projecthave ensured accurate geographic feature data on USGS Topographic Maps. Theyand the Geographic Names Information System now are serving the growing Geo-graphic Information System communities

40、in the same manner.The ChallengeThe explosive growth of geographic information systems and internet-based applica-tions and services have generated multitudes of related, overlapping, and potentiallycontradictory datasets containing geographic feature data, served by multiple, inter-locking, and int

41、erdependent applications at all levels of government and the privatesector. It is virtually impossible to correlate the many different sets of feature data containingthousands, tens of thousands, or more records based solely on attribute compari-sons with any assurance that they mutually address the

42、 same features, record forrecord. Unregulated text fields, particularly feature names, may contain wide varia-tions of spelling, content, presentation, and errors that are outside the control of thedata owners. Locational attributes are subject to multiple variations and differing in-terpretations.

43、Geospatial representations frequently exist in multiple versions at vary-Copyright American National Standards Institute Provided by IHS under license with ANSI Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-iving scales and levels of accuracy. Many geographic fea

44、tures have no definable,official, recognized, or agreed upon boundaries, for example, the eighty percent ofcommunities in the United States that are unincorporated, or a mountain for whichthere is really no algorithm for determining feature extent. Therefore, there is no known mechanism for ensuring

45、 at the national level that relat-ed datasets contain and are serving mutually consistent feature data, or that stateand local data are properly represented in federal datasets. For over a hundredyears, the USGS National Base Map series provided the only consistent, nationalgeospatial representation

46、 available, but for many critical purposes, printed mapshave been rendered obsolete by technology.The implications of incorrect, inaccurate, or contradictory feature data appearing si-multaneously in multiple Internet applications are serious and potentially catastrophicwith regard to national secur

47、ity, emergency preparedness and response, regionaland local planning, site selection and analysis, cartographic applications, environ-mental problem-solving, tourism, and all levels of communication. This standard is in-tended to help correct this deficiency.This standard contains one informative an

They should be sent to InterNational Committee for InformationTechnology Standards (INCITS), ITI, 1250 Eye Street, NW, Suite 200, Washington,DC 20005
