Metadata

What follows is very detailed technical information about this dataset. This is often called metadata. Metadata (or "data about data") describe the content, quality, condition, and other characteristics of data. Metadata are used to organize and maintain investments in data, to provide information to data catalogs and clearinghouses, and to aid data transfers. The Federal Geographic Data Committee (FGDC) publishes the Content Standard for Digital Geospatial Metadata. Many organizations within and outside of the federal government have adopted the FGDC metadata standard and are using automated indexing and serving mechanisms to provide access to their holdings through the Internet. Visit the FGDC Clearinghouse to learn more about how metadata is used in clearinghouses and to search for other data sets.

Description:

Abstract:

This data set includes airports in the United States, Puerto Rico and the U.S. Virgin Islands. The data were derived from the National Transportation Atlas Databases 1997 (NTAD97) produced by U.S. Department of Transportation (DOT) which is based on information provided by the Federal Aviation Administration (FAA). A subset of the complete list of airports was extracted, based on airport passenger enplanement of greater than or equal to 250 passengers per year.

Purpose:

These data are intended for geographic display and analysis at the national level, and for large regional areas. The data should be displayed and analyzed at scales appropriate for 1:2,000,000-scale data. No responsibility is assumed by the U.S. Geological Survey in the use of these data.

Process_Description:

Data from the NTAD97 CD-ROM were obtained from the Department of Transportation. Using the airport.pnt and airport.t01 files on the CD-ROM, airports with passenger enplanement of greater than or equal to 250 passengers per year were selected to create a point coverage to which the following attributes were attached: airport location identifier, name of airport, name of State, State FIPS code, Air Carrier Activity Information System airports, and Total Enplanement. The data were converted to shapefile format for use in National Atlas applications and for distribution to the public.

Process_Date: 1998

Source_Produced_Citation_Abbreviation: ATLAS_AP

Process_Step:

Process_Description:

Airports for Puerto Rico and the U.S. Virgin Islands were added. Airport names were changed from all upper case and no period after initials to lower case and period after initials. For example, LYNDON B JOHNSON is now Lyndon B. Johnson.
