Name: Navigation Channels
Display Field: CHANNELARE
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: This layer is a component of the National Channel Framework (NCF), an enterprise Geographic Information System (eGIS) database providing information about congressionally authorized navigation channels maintained by the US Army Corps of Engineers. This layer includes channel area details based on district-managed GIS polygons rather than on CAD-based linework, and is maintained through the eHydro hydrographic survey application. Additional NCF details, including channel reaches, quarters, and centerlines can be found at the <a href="https://geospatial-usace.opendata.arcgis.com/datasets/9227967a2748410983352b501c0c7b39" target="_blank"> US Army Corps of Engineers Geospatial Open Data site</a>.
