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.
Data sources used in this process:
Data sources produced in this process:
- Date: 16-Feb-1999 (process 2 of 3)
-
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.

Data sources produced in this process:
- Date: 05-Aug-2001 (process 3 of 3)
-
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.
Data sources used in this process:
- ATLAS_AP99
- NTAD-2001
- ACAIS
