New Edition of US Chart No. 1 Available

The new edition updates the descriptions and depictions of the basic nautical chart elements and symbols used on nautical charts produced by the National Oceanic and Atmospheric Administration (NOAA) and the National Geospatial-Intelligence Agency (NGA). The document also shows the "INT1" symbols described in the Chart Specifications of the IHO published by the International Hydrographic Organization (IHO). It supersedes the November 1997 edition of U.S. Chart No.1.

The version of U.S. Chart No. 1, in PDF format can be downloaded from the Office of Coast Survey website. It will also be available from the NGA Maritime Safety Information site by 10 December.

NGA will officially announce the 11th edition in US Notice to Mariners 51/2011. The Notice will have a cover date of 17th December 2011.

NOAA and NGA jointly produce U.S. Chart No.1. Preparations for Edition 12 are already underway and publication is anticipated by 2013. Edition 12 will feature the addition of the symbols specified by the IHO for the portrayal of electronic navigational chart (ENC) data on Electronic Chart Display and Information Systems (ECDIS).

In regards to the POLL to my right which does not give me this choice. The most interesting hydographic activity and perhaps the only Hydrographic activity that should be called hydrography is the production of nautical charts. All other sea related activities regarding positioning and sea depth should be called Ocean Engineering. Finding a hole in the sea floor in which to shove in a pipe could hardly be called "graphic" Barry M. Lusk - 15/12/2011 - 21:32
