    <abstract lang="eng" displayLabel="Abstract">This point shapefile depicts aircraft landing facilities in the United States and United States 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. This geospatial data is derived from the Federal Aviation Administration's (FAA) National Airspace System Resource Aeronautical Data Product. The FAA develops and maintains this textual data from which this geospatial layer was derived. This layer is part of the 2014 National Transportation Atlas Database.</abstract>
    <abstract lang="eng" displayLabel="Purpose">The National Transportation Atlas Databases 2014 (NTAD2014) is a set of nationwide geographic datasets of transportation facilities, transportation networks, associated infrastructure and other political and administrative entities. These datasets include spatial information for transportation modal networks and intermodal terminals, as well as the re&#xAC;lated attribute information for these features. This data supports research, analysis, and decision-making across all transportation modes. It is most useful at the national level, but has major applications at regional, state and local scales throughout the transportation community. The data used to compile NTAD2014 was provided by our partners within the United States Department of Transportation (USDOT) and by other agencies throughout the United States Federal Government. These contributors are the actual data stewards and are ultimately responsible for the maintenance and accuracy of their data. The data provides users with information about airport locations and attributes and can be used for national and regional analysis applications.</abstract>
