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.

DK3HORRO is divided into three cells: DK30529D, DK30533D, and DK30133D.
All three cells have been approved and released.

DK3BORNH is divided into five cells: DK30557D, DK30561D, DK30153D, DK30147D, and DK30161D.
All five cells have been approved and released.

The eastern DK3 cells will be divided into 10 cells: DK31337D, DK31341D, DK31345D, DK30941D, DK30945D, DK30949D, DK30541D, DK30545D, DK30549D and DK30533D.
All 10 cells have been approved and released.

 

PHASE 2: AUGUST-SEPTEMBER 2024

Phase 2 has been updated with a new priority. It has been chosen to prioritize the south-eastern DK4 grids, as the area contains the test areas for the Baltic Sea e-Nav project. You can read more about the project and the involvement of the Danish Geodata Agency's on this page: Baltic Sea e-Nav. Expected release of the DK4 cells is mid-September. Further in phase 2, the DK2 cells are sent for validation and are released at the end of September or the beginning of October.

DK4 cells will be divided into 24 cells: DK40951E, DK40751E, DK40749E, DK40747E, DK40745E, DK40743E, DK40741E, DK40553E, DK40551E, DK40549E, DK40547E, DK40545E, DK40543E, DK40541E, DK40353E, DK40351E, DK40349E, DK40347E, DK40345E, DK40343E, DK40341E, DK40149E, DK40147E, and DK40145E.

DK2 cells will be divided into 16 cells: DK20109C, DK20117C, DK20125C, DK20133C, DK20141C, DK20149C, DK20157C, DK20165C, DK20909C, DK20917C, DK20925C, DK20933C, DK20941C, DK20949C, DK21733C, and DK21741C.

 

PHASE 3: OCTOBER 2024-NOVEMBER 2024

In phase 3 the release of DK4 cells are split into three: DK4 release 2 north east, DK4 release 3 south west, and DK4 release 4 north west. At the end of phase 3, the release of the DK1 cells is assessed.

DK4 release 2 will be divided into 22 cells: DK41343E, DK40539E, DK40943E, DK40739E, DK40339E, DK41345E, DK40537E, DK41347E, DK41139E, DK40337E, DK40949E, DK41145E, DK40941E, DK41141E, DK41339E, DK41543E, DK41147E, DK41149E, DK40947E, DK40945E, DK41143E, and DK41341E.

DK4 release 3 will be divided into 3 cells: DK40335E, DK40533E, and DK40535E.

DK4 release 4 will be divided into 8 cells: DK40733E, DK40933E, DK40935E, DK41133E, DK41135E, DK41137E, DK41335E, and DK41337E.

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..
