Item Identification

Title: Coastal Maintained Channels
Status: Completed
Publication Date: 2018-07-01
Abstract:

This layer shows coastal channels and waterways that are maintained and surveyed by the U.S. Army Corps of Engineers (USACE). These channels are necessary transportation systems that serve economic and national security interests. The possibility of silting is always present. Local authorities should be consulted for the controlling depth. NOS Charts frequently show controlling depths in a table, which is kept current by the US Coast Guard Local Notice to Mariners.

Purpose:

To support coastal and ocean planning and other activities pursuant to the Energy Policy Act, Coastal Zone Management Act, Magnuson-Stevens Fishery Conservation and Management Act, National Environmental Policy Act, Rivers and Harbors Act and the Submerged Lands Act.

Supplemental Information:

The native coordinate system for this layer is WGS 1984 World Mercator (ESPG: 3395). Please note: all MarineCadastre.gov data served by the NOAA Office for Coastal Management and hosted through Esri REST services are in the WGS 1984 Web Mercator Auxiliary Sphere (EPSG: 3857) projection.

Process Step 2

CC ID: 791082
Description:

Project CoastalMaintainedChannelsUS polygons into WGS 1984 World Mercator and repair feature geometry.

Process Date/Time: 2018-06-15 00:00:00

Process Step 3

CC ID: 791083
Description:

Dissolve adjacent features on "OBJNAM" and "FAIRWAY" fields to single-part polygons. Extract resulting features that intersect state or federal waters as delineated by FederalAndStateWaters. Check and consolidate "OBJNAM" and "FAIRWAY" attribution into the "OBJNAM" field where necessary, then dissolve adjacent features with identical attribution in "OBJNAM" field.
