Miscellaneous Notices to Mariners

6 Print on Demand

The Norwegian Hydrographic Service offers a Print on Demand (POD) service. Print on Demand service is offered for all Norwegian charts and can be purchased from approved suppliers of The Norwegian Mapping Authority's maps and charts.

Traditionally, paper charts were issued every few years. As time passes, there would be messages from the Norwegian Notices to Mariners, Etterretninger for sjøfarende (Efs), that were not reflected in the chart at selling time. This meant that even though the chart was bought today, many important corrections could have been issued since the chart was printed, and mariners had to manually update the chart with the Efs updates since the chart was published. With POD this is no longer necessary, as POD-charts are automatically and continuously updated to the latest Efs.

When a POD chart is purchased, the mariner only has to review the Efs’ published after the POD production, in order to have a fully updated chart. This will typically be limited to the latest Efs.

Chart updating starts as soon as an Efs is published. All updates shall be performed before the next Efs is issued (i.e. during a 14 day period). POD charts may also include updates that have not yet been published in an Efs.

A POD chart differs from a traditional chart in several ways:

  • "Print on Demand" is printed in red text on the left and right side of the chart frame.
  • A text box in the lower left corner displays different dates and Efs reference.
