Plan for implementation of ENC-grid in Denmark

On this page you will find the Danish Geodata Agency’s implementation plan for the new grid in Denmark plus information regarding newest updates and changes.

The Danish Geodata Agency has chosen to introduce a grid of the Danish ENC’s (electronic nautical charts) with the start in June 2024. The new grid will make it easier to compile data and ensure more consistent data management. The project is a part of the preparation for the electronic charts, S-100, which will be released in 2026. You can read more about this here.

To ensure that the process runs as smoothly as possible, the Geodata Agency has created a plan, which you can read more about below. We would like to point out that changes to the plan may occur.

Phases of implementation

Below, you can learn about the Geodata Agency's plan for the introduction of the grid in Denmark. The introduction will take place in several phases. Each phase will include multiple releases. Please note that we cannot provide specific dates for the releases, as these are dependent on validation from IC-ENC.

If you have any questions about the project, you are welcome to contact the Office for Nautical Charts and Marine Data.

Did you know that the Danish Geodata Agency’s electronic charts (ENC) are validated and distributed by IC-ENC?

IC-ENC is the Danish Geodata Agency’s distributor of electronic charts (ENC). This is why we cannot give you any precise dates for the releases of the new ENCs. The validation process takes 3 to 10 days.
You can read more about IC-ENC here.

PHASE 1: JUNE-JULY 2024

The first phase involves the Danish DK3 cells.

In the first release DK3HORRO will be divided into three new cells: DK30529D, DK30533D and DK30133D.

 

Hereafter DK3BORNH will be divided into five cells with the names DK30557D, DK30561D, DK30153D, DK30147D and DK30161D.

In the end of phase one the eastern DK3 cells will be divided into 12 cells with the names DK31337D, DK31341D, DK31345D, DK30941D, DK30945D, DK30949D, DK30541D, DK30545D, DK30549D, DK30533D, DK30145D and DK30149D. For the moment it is unclear if the 12 new cells will be released in one or two releases.

More information will follow.

PHASE 2: AUGUST-SEPTEMBER 2024

Phase 2 depends on the releases and the lessons learned from Phase 1. Therefore, the planning for the DK2 cells and DK4 cells will begin at a later date. More information on this will follow later.

PHASE 3: OCTOBER 2024-JANUARY 2025

In the third phase, the remaining DK4 cells will be released, followed by the final release of the DK1 cells.

More information will follow.

New naming convention for Danish ENC-cells

The new grid means that there will be a more systematic approach to cell division, resulting in more cells. In conjunction with this, the naming convention of the cells will be changed to ensure uniformity. Therefore, if you are planning to sail in Danish waters, you should be aware of the new naming convention.

While the previous naming convention aimed to indicate which body of water or area a cell was located in, the new naming convention intends to specify the cell's location according to the earth's latitude and longitude.

Naming an ENC-cell
An ENC cell name consists of eight characters. The first two letters indicate the name of the hydrographic office that publishes the cell. In Denmark and Greenland, this is DK. The third character indicates which band the cell is in. There are five different bands in Denmark.

Band 1 is overview charts, Band 2 is general, Band 3 is coastal, Band 4 is approach, while Band 5 is harbor cells. Cells in Band 5 are not included in the project to introduce a grid in Denmark.

Previously, the last five characters in the cell names aimed to indicate which body of water or location was being referred to. With the introduction of a grid, this changes to instead indicate the cell's position according to the earth's latitude and longitude. The table below shows how the naming convention is determined. The following image illustrates how the naming of the Danish DK[band] cells will be after the new grid is implemented..
