Attribute and geospatial data
[Date: 1998] Data from the National Transportation Atlas Databases 1997 (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. [Date: 19990216] 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.
The following steps were performed by ESRI: Downloaded the ArcView Shapefile version of the data, airprtx020.tar.gz, from http://www.nationalatlas.gov/atlasftp.html and extracted it. Removed unneeded attributes. Created ArcGIS™ layer file (.lyr). Created ArcView legend file (.avl). Created projection file (.prj). Ran ArcView Avenue request ExportClean, and created spatial indices.

The horizontal positional accuracy is unknown.
After processing, the data set is checked for drawing display and number of records and file sizes compared with source materials.
No duplicate features are present. The shapefile is exported using Avenue request ExportClean. This request verifies and enforces the correctness of shapes.
