The shapefile is converted to SDC (Smart Data Compression) format using either ESRI SDC Data Development Kit Professional 2 (DDKP2) or tools in ArcGIS. The SDC data set is then loaded into ArcSDE® to verify and validate the geometry.
After processing, the data set is checked for drawing display and number of records and file sizes compared with source materials.
The horizontal positional accuracy is unknown.

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. 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. Airports of the United States, Puerto Rico and the U.S. Virgin Islands 1999 was updated with enplanement data from National Transportation Atlas Databases 2001 (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 Airports of the United States, Puerto Rico and the U.S. Virgin Islands 1999: Feature, indicating the type of facility, name of County, and County FIPS code.
The following steps were performed by ESRI: Downloaded the ArcView GIS Shapefile compressed file, airprtx020.tar.gz, from the National Atlas of the United States® and extracted it. Removed unneeded attributes. Changed the values of the STATE attribute from abbreviations to full names. Added attribute ACAIS and coded it from ESRI Data & Maps 2002 U.S. National Atlas Airports and FAA CY1999 ACAIS data base. Created ArcGIS® layer file (.lyr), projection file (.prj), and spatial indices. Converted the data set to SDC.
The following steps were performed by ESRI: Updated the TOT_ENP attribute and populated it with 2003 Federal Aviation Administration data of greater than or equal to 100 passengers per year. Added the FIELD attribute and populated it with airfield names from the NAME attribute. Added the TYPE attribute and populated it based on the NAME attribute and North American Transportation Atlas Data.
