Chart 1

PRINTING TO BE DISCONTINUED
Due to the availability of Chart 1: Symbols, Abbreviations and Terms as both printable PDF files and HTML format on charts.gc.ca, the Canadian Hydrographic Service is permanently discontinuing the printing of Chart 1: Symbols, Abbreviations and Terms starting January 2021. Advances in technology bring a new era of marine navigation with a focus on digital and electronic products. The Canadian Hydrographic Service is transforming the way it delivers quality data and services to clients, in a timely manner, to support decision-making.

Chart 1 is a publication containing explanations of the symbols, abbreviations and terms needed to interpret nautical charts published by the Canadian Hydrographic Service. Member nations of the 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.

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

  • Please be advised that if you intend to print from the PDF the size expands substantially when uncompressed en-route to the printer.
  • Note on Printing: Due to the importance of colour in symbology printing in black and white only is strongly discouraged. Colour laser and ink jet printers are recommended.

Chart 1, 2016 edition booklet is available for purchase from an Authorised Chart Dealer.
