Chart 1: Symbols Abbreviations Terms

Chart 1 is a publication containing explanations of the symbols, terms and abbreviations needed to interpret nautical charts published by the Canadian Hydrographic Service. Member nations of the IHO (International Hydrographic Organization) produce Chart 1 using a common format. That common format consists of Sections identified by letters and symbols, abbreviations, or terms identified by a reference number. All Chart 1s organize these Sections and symbols, abbreviations, or terms in the exact same order.

This edition of Chart 1 has been produced as a booklet and is also being posted to the CHS Web Site in pdf and in html format.

The booklet is available for purchase from an Authorised Chart Dealer.

To view Chart 1 as a pdf document, you must have a PDF reader installed. See help for more information.
