The Norwegian Mapping Authority's nautical charts are available as Print on Demand charts (POD). POD charts refer to updated charts printed by retailers on request from the public. Through the Print on Demand service, charts are updated with all safety critical updates up to and including the most recent Notices to Mariners (Efs). After purchase, the user must keep the chart updated using Efs. To buy the official Norwegian nautical charts, contact our POD distributors in Norway and abroad.

The nautical charts are updated with the aid of the Notices to Mariners (Efs), published every 14 days. A POD chart will be in accordance with the requirements of the International Maritime Organization (IMO)/SOLAS. All Norwegian nautical charts are available as POD charts only.
