Project Description

Project Title:  View help for Project Title HIFLD OPEN obstruction-areas-usace-ienc-2
Summary:  View help for Summary The USACE Inland Electronic Navigation Charts (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 which the National Oceanic and Atmospheric Administration (NOAA) does not produce Electronic Navigational Charts (ENCs). However, Special Purpose IENCs may be produced in agreement with NOAA.  IENC POC: [email protected]
