U.S. and Canada eliminate overlapping ENC coverage in the Great Lakes

Countries issue advance notice for changes in electronic charts

To comply with internationally agreed practices, Canada and the U.S. have been eliminating overlapping coverage of electronic navigational charts (ENCs). New changes will soon take effect in the Great Lakes. Under the new ENC coverage scheme, each country is changing their areas of coverage so that only one country’s ENC is available for any given area at a particular scale.

These changes come into effect 0000 Coordinated Universal Time (UTC), on 22 February, 2013.

Coast Survey’s ENC Overlap webpage has images depicting changes to the ENC coverage in the Great Lakes. (Mouseover the images to switch between original coverage and revised coverage.) It also lists the revised ENC limits as agreed upon by Canada and the United States.

The U.S. and Canada are making these changes to comply with the International Hydrographic Organization Worldwide Electronic Navigational Chart Database principles. According to those principles, countries should avoid ENC duplication, with only one country responsible for producing electronic charts for any given area. The U.S. and Canada revised ENC coverage last year for overlapping regions in Pacific and Atlantic regions.

Coast Survey supports inauguration preparations

It was an honor to assist with preparations for the Presidential Inaugural.  Our assistance, provided before the event, was a combined effort by one of our navigation response teams, survey technicians, cartographers, and several NOAA officers. Coast Survey’s work was additionally supported by colleagues at NOAA’s Center for Operational Oceanographic Products and Services.

What is the future of e-Navigation? CMTS wants to hear from you

The U.S. Committee on the Marine Transportation System, a federal inter-agency partnership that develops national MTS policy, is asking for your ideas on the future of e-navigation.

They’ve set up a unique online site to facilitate the conversation, and they invite anyone with an interest in the U.S. marine transportation system to join the discussion. (Deadline for comments is February 28.) For background, you might want to read the committee’s e-Navigation Strategic Action Plan.

DSC_0049As defined by the International Maritime Organization (IMO), e-navigation is “the harmonized collection, integration, exchange, presentation, and analysis of maritime information onboard and ashore by electronic means to enhance berth-to-berth navigation and related services for safety and security at sea and protection of the marine environment.”

The committee’s e-Navigation Integrated Action Team will consider your comments as they develop their work plan and recommendations. They will also provide an analysis of all of the feedback this spring or early summer.  We will let you know when the analysis is posted, or you can monitor the CMTS website.

The CMTS Integrated Action Team leads for e-navigation are NOAA, the U.S. Army Corps of Engineers, and the U.S. Coast Guard. Participating agencies are:

  • National Oceanic and Atmospheric Administration
  • National Transportation Safety Board
  • Oceanographer of the Navy
  • Research and Innovative Technology Administration
  • U.S. Army Corps of Engineers
  • U.S. Coast Guard
  • U.S. Maritime Administration
  • U.S. Transportation Command
