HIFLD OPEN Airport Area (USACE IENC)

This dataset contains airport areas within the US Army Corps of Engineers Inland Electronic Navigational Charts (IENCs). The IENCs coverage area consists of 7,260 miles across 21 rivers primarily located in the Central United States. IENCs apply to inland waterways that are maintained for navigation by USACE for shallow-draft vessels (e.g., maintained at a depth of 9-14 feet, dependent upon the waterway project authorization). Generally, IENCs are produced for those commercially navigable waterways for which the National Oceanic and Atmospheric Administration (NOAA) does not produce Electronic Navigational Charts (ENCs).<br><br>Airport areas here are defined as containing at least one runway, used for landing, take-off, and movement of aircraft.
