Description:

  Abstract: The Public-Use Airports database is a geographic

     point database of aircraft landing facilities in the United

     States and U.S. Territories.  Attribute data is provided on

     the physical and operational characteristics of the landing

     facility, current usage including enplanements and aircraft

     operations, congestion levels and usage categories.

 

  Purpose:  The database provides locational and attribute

     information for use in national and regional cartographic

     and spatial analysis applications.

                   Data_Quality_Information:

 

Attribute_Accuracy:

  Attribute_Accuracy_Report:  Airport attributes were obtained

     from the Federal Aviation Administration (FAA) National

     Flight Data Center Airport Master Record (NFDC 5010)

     database and the Office of Airline Information (OAI).

 

     Some airport features in this version are not assigned Site

     Numbers (SITE_NO).  These are airports where the location

     identifier (LOCID) did not match any current record in the

     NFDC data.  These features have no corresponding records

     in any attribute file.  They were not deleted from this

     version in anticipation of performing a more thorough review.

    

Logical_Consistency_Report:   All point records are

     represented by a single coordinate pair and a unique

     feature identifier -- the landing facility's location

     identifier (LOCID) and Site Number (SITE_NO) assigned by

     the FAA. 

 

 Completeness_Report:  Landing facilities in this database

    consist of those identified in the NFDC 5010 database to be

    either publicly owned, or privately owned but open to the

    public, or owned by the U.S. military.  The following

    landing facilities have been excluded:  private landing

    facilities not open to the public, glider ports and ultra

    light landing facilities, as well as landing facilities that

    do not have a current LOCID assigned to them

 

Positional_Accuracy:

  Horizontal_Positional_Accuracy:

     Horizontal_Positional_Accuracy_Report:  Horizontal positional

       accuracy is based on coordinate data provided

       in the NFDC 5010 database.  These coordinate data

       identify the approximate location of the Airport

       Reference Point (ARP) as reported by the landing facility

       on the NFDC 5010 form.  According to NFDC guidelines, the

       location of the ARP should be reported to a horizontal

       accuracy of one arc second of latitude and longitude.

       However, the accuracy of these reported coordinates are

       not verified by FAA.  The records were loaded into a GIS

       and checked for any unusual or obviously erroneous locations.
