Channel Framework
Channel Framework

The National Channel Framework (NCF) is an enterprise Geographic Information System (eGIS) geodatabase of high-and medium-tonnage Congressionally authorized navigation channels maintained by the US Army Corps of Engineers (USACE). It serves as the basis for the National Oceanic and Atmospheric Administration's (NOAA) paper and Electronic Navigation Charts (ENCs) as well as other products. Simply speaking, it is a 3D waterway roadmap that plots channel boundaries, areas, quarters, reaches, centerlines, and stationing.
