Public-Use Airports - Data Dictionary

Abstract: The 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. There are 20491 airport landing facilities in this dataset. This geospatial data is derived from the FAA's National Airspace System Resource Aeronautical Data Product (Effective 18 Jaunary 2007).

Purpose: The dataset provides users with information about airport locations and attributes and can be used for national and regional analysis applications.
