Description
A characterization of the data, including its intended use and limitations.
Abstract:
The Geographic Names Information System (GNIS), developed by the U.S. Geological Survey in cooperation with the U.S. Board on Geographic Names (BGN), contains information about physical and cultural geographic features in the United States and associated areas, both current and historical, but not including roads and highways. The database also contains geographic names in Antarctica. The database holds the Federally recognized name of each feature and defines the location of the feature by state, county, USGS topographic map, and geographic coordinates. Other feature attributes include names or spellings other than the official name, feature designations, feature class, historical and descriptive information, and for some categories of features the geometric boundaries. The database assigns a unique feature identifier, a random number, that is a key for accessing, integrating, or reconciling GNIS data with other data sets. The GNIS is our Nation's official repository of domestic geographic feature names information.
Purpose:
The GNIS is the official vehicle for geographic names use by the Federal Government and the source for applying geographic names to Federal maps & other products. The GNIS supports the U.S. Board on Geographic Names (BGN), a Federal body created in 1890 and established in its present form by Public Law in 1947. The Board serves the Federal Government, other government agencies, and the public as the central authority to which name inquiries, name issues, and new name proposals can be directed. The GNIS provides the data to government agencies and to the public. The GNIS also supports the U.S. Geological Survey National Map (http://nationalmap.usgs.gov/) as the source for the gazetteer search in The National Map viewer and as an active layer in The National Map for Federal boundaries and geographic features not available from state or local sources.
Supplemental information:
The U.S. Board on Geographic Names Comprised of representatives of Federal agencies, appointed for 2-year terms, the Board is authorized to establish and maintain uniform geographic name usage throughout the Federal Government. Sharing its responsibilities with the Secretary of the Interior, the Board has developed principles, policies, and procedures governing the use of both domestic and foreign geographic names as well as undersea and Antarctic feature names.

Other citation details:
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.

CLASS
Definition:
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.

PRIMARY_LAT_DMS
Definition:
Primary Point Latitude - The latitude of a point locating a geographic feature, also termed the feature application. Along with the feature name, the application is approved or recognized as official either by policy or by decision of the United States Board on Geographic Names for use throughout the Federal Government. A geographic feature may have only one primary point regardless of size or extent. A point feature is defined by this single set of coordinates on the USGS National Base Map series at a scale of 1:24000 or 1:25000. The primary point of a linear feature depends on the feature class. If feature class equals stream, valley or arroyo, the primary point is the mouth. The primary point of a canal, channel, or trail is the center. The primary point of a ridge is the highest point. The primary point of an areal feature is the approximate geographic center with the following exceptions: The primary point of a populated place is the center of original place such as the city or town hall, main post office, or town square regardless of changes over time. The primary point of a reservoir is the center of the dam. The primary point of a summit, range, ridge, or pillar is the highest point. The primary point has a sequence number of 1. These points do not represent boundaries or geometries and should not be confused with them. An application may be displayed as latitude and longitude data or as a point in a geographic information system, and may be applied as label points.

The primary point of an areal feature is the approximate geographic center with the following exceptions: The primary point of a populated place is the center of original place such as the city or town hall, main post office, or town square regardless of changes over time. The primary point of a reservoir is the center of the dam. The primary point of a summit, range, ridge, or pillar is the highest point. The primary point has a sequence number of 1. These points do not represent boundaries or geometries and should not be confused with them. An application may be displayed as latitude and longitude data or as a point in a geographic information system, and may be applied as label points.

SOURCE_LAT_DMS
Definition:
Secondary Point Latitude - The latitude 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 Geographic Names Office. 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 may be displayed as latitude and longitude data or as points in a geographic information system and may be applied as label points.

Create GeoDatabase Feature Class - Downloaded the Connecticut data extract from the Geographic Names Information System (GNIS) at http://geonames.usgs.gov/domestic/download_data.htm as a tab delimited text (.txt) file named CT_DEC.txt.The downloaded file contain primary feature attributes, but do not contain all attributes. The downloaded file reflects GNIS data last updated by USGS on September 19, 2006. Imported tab delimited data into MS Excel, imported the MS Excel data into an ESRI Personal Geodatabase as a conventional MS Access data table, and using ESRI ArcCatalog software registered the MS Access data table as a Personal GeoDatabase data table. Using ESRI ArcMap software, created a point event layer based on the Primary_lat_dec and Primary_lon_dec attribute values in the data table, projected the point data to the Connecticut State Plane Coordinate System, NAD 83 (map units feet), and exported the data to a point Feature Class named USGS_Geographic_Name in the ESRI Personal Geodatabase. Downloaded metadata for the GNIS data in XML format from http://geonames.usgs.gov/GNIS.html and, using ArcCatalog softwre, imported the metadata document to describe the USGS_Geographic_Name point Feature Class. Modified the metadata to reflect these processing steps and enumerate the Class attribute as described in http://geonames.usgs.gov/domestic/feature_class.htm.
