Releases of paper nautical charts

If corrections to a chart are so complex or extensive that it is not possible to describe them using chart corrections, a new edition of the chart is published. This applies in particular if depths and depth contours are to be corrected based on depth data from a new hydrographic survey. Upon the publication of a new edition, the previous edition of the chart is cancelled.
If changes occur in the navigation pattern, changes in the requirements for the chart's coverage/scale or similar, a new chart is produced and published. A new chart can either replace an existing chart or supplement the chart portfolio.
The publication of new editions of charts and new charts is announced in the table.

The Danish Geodata Agency assesses incoming information and data from various sources and if it triggers updates to nautical chart products. If updates are required, a chart correction is issued for paper charts.

Additionally, depth data from hydrographic surveys conducted by the Danish Geodata Agency's Maritime Survey Unit or other entities is processed. Changes in depths and depth contours cannot be addressed through standard chart corrections. Therefore these changes will be reflected only when a new edition of the affected paper charts is published.

For the majority of chart corrections, Notices to Mariners (EfS) serve as the primary source. A smaller portion of chart corrections is based on information and data from stakeholders such as ports, contractors, cable owners and other entities.

If the required corrections to a chart are too extensive to be applied via standard chart corrections, a new edition of the chart will be published. When a new edition is published, the previous edition is withdrawn.

Upon publication, paper charts include all corrections up to and including the date indicated in the lower-left corner of the chart. When acquiring a paper chart, users should be aware that any corrections released after this specified date must be manually added to the chart.
