The data were derived from an extract of The Public- Use Airports database of the National Transportation Atlas Databases-2001 (NTAD-2001), published by the Bureau of Transportation Statistics, Department of Transportation. 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.

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. Source_Used_Citation_Abbreviation: NTAD97 Process_Date: 1998 Source_Produced_Citation_Abbreviation: ATLAS_AP98 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. Source_Used_Citation_Abbreviation: ATLAS_AP98 Process_Date: 19990216 Source_Produced_Citation_Abbreviation: ATLAS_AP99 Process_Step: Process_Description: ATLAS_AP99 was updated with enplanement data from NTAD-2001. Existing airports, heliports, and seaplane bases with enplanements of 250 or greater were kept in the data set, while those below 250 enplanements were deleted. Sixty-five airports, heliports, and seaplane bases that had 250 or greater enplanements were added. The following attributes were added to ATLAS_AP99: Feature, indicating the type of facility, name of County, and County FIPS code.
