The Danish Geodata Agency is launching a digital guide to navigational planning in the Baltic Sea

Published 22-05-2017

The new digital guide, Mariners' Routeing Guide Baltic Sea, will make it easier and safer to navigate the Baltic Sea.

In marine areas with complex route systems, including systems for monitoring and guidance of maritime traffic and ship reporting systems, it may be difficult for navigators, shipping companies and others to manage all the requirements and recommendations that apply to ship navigation.

Digital guide
In order to facilitate the ships’ route planning, the countries around the Baltic Sea agreed to publish a special, English-language route guide called Mariners' Routeing Guide Baltic Sea. The Danish Geodata Agency has now digitized and published the guide.

"I am delighted that the Danish Geodata Agency has taken another important step towards digitizing maritime data for shipping. The Baltic Sea has high levels of shipping activity and complex route systems, where easy access to updated nautical information is crucial for navigational safety," says Lars Chr. Lilleholt, Minister for Energy, Utilities and Climate.

Interactive map With the new digital guide, navigators can familiarise themselves in advance about e.g. traffic separation systems, deepwater routes, reporting points, etc. This can be done both by referring to the website or by consulting the interactive map of the Baltic Sea.

"By digitizing the information, we can continuously update the guide while also presenting the data in a convenient and comprehensible manner. Eventually, it will also be possible to integrate the data into other systems and initiatives such as the Marine Geographic Data Infrastructure," explains Elizabeth Hagemann, Area Manager in Nautical Charts Denmark and Administration at the Danish Geodata Agency.
