A large part of the German authorities responsible for coastal and marine areas are partners in the MDI-DE administrative agreement. They merge data and information from the subject areas of basic marine data, coastal engineering, marine environmental protection and marine nature conservation in a specialized portal to jointly fulfill national and international information obligations of the authorities.

Organizational structure

The steering group adopts the annual work program and decides on the current budget for the operation and further development of the MDI-DE. It is composed of representatives of the responsible ministries of the federal government and the coastal states.

The project management and the budget management are currently carried out by the Federal Agency for Nature Conservation (BfN).

The project group determines the strategic and technical orientation of the MDI-DE in agreement with the steering group. If required, the members of the project group from the partner authorities form temporary working groups with the support of an IT service provider.

The working groups are convened by the project manager to work on specific topics and products of the MDI-DE. The focus is on merging distributed heterogeneous data sets into joint thematic services. The results of the work are recorded and published in guidelines to give information about the development, maintenance and recommendations for action. These documents are updated as needed and describe, in particular, the content and technical agreements for data harmonization and interoperability.

The following authorities are partners of MDI-DE:

The Federal Waterways Engineering and Research Institute (BAW) is the higher technical and scientific federal authority in the portfolio of the Federal Ministry for Digital and Transport (BMDV) with locations in Karlsruhe and Hamburg. The BAW is the central service provider for advising and supporting the Ministry and the Federal Waterways and Shipping Administration (WSV) within the scope of their transport water engineering tasks, in particular their responsibility under construction supervision for ensuring that all facilities and installations on federal waterways meet the requirements of safety and order. Through its work, it makes a significant contribution to ensuring that Germany’s waterways meet the growing technical, economic and ecological requirements. At the Hamburg site, the focus is on hydraulic engineering in the coastal area. In addition, the Geotechnical Engineering North and Coast department, the Ship Technology department and the KFKI office are located there.

Within the MDI-DE, the BAW provides data from coastal engineering, such as high tide, low tide, salinity, bathymetry and sea state characteristics from the EasyGSH-DB project.

The State Agency for Environment in Schleswig-Holstein (LfU) is a higher state authority subordinate to the Ministry for Energy Transition, Climate protection, the Environment and Nature (MEKUN) in Kiel. Environmental issues relating to the marine sector are dealt with by the Coastal Waters Department. One of the main tasks of the department is to monitor the state of the environment in the coastal waters of Schleswig-Holstein, also in order to plan urgent measures and check their effectiveness. In addition, there is the recording and evaluation of species and habitats of the seas and coasts. Here, there are close interfaces with the tasks of nature conservation. The investigations carried out and the data and assessments collected are largely used for the implementation of directives in the field of marine and water protection. In particular, the Marine Strategy Framework Directive (MSFD), the Water Framework Directive (WFD), the Habitats Directive and the regional agreements OSPAR and HELCOM should be mentioned.

Together with the State Agency for Coastal Protection, National Park and Marine Conservation (LKN), LfU operates the MDI-SH infrastructure node and uses it to provide data on marine priority topics for Schleswig-Holstein.

Since 2005, the tasks of water management and nature conservation to be performed directly by the state have been concentrated at the Lower Saxony State Agency for Water Management, Coastal Protection and Nature Conservation (NLWKN).

Environmental monitoring based on the EU Water Framework Directive (WFD) for the coastal area of Lower Saxony is one of the tasks of the NLWKN, whereby biological and chemical investigations are carried out in the estuaries, in the Wadden Sea and in the offshore coastal waters. The measurement programs on which this monitoring is based are coordinated within the framework of the Federal/State Working Group North Sea and Baltic Sea (BLANO).

The NLWKN coordinates the management planning of the WFD for the area of transitional and coastal waters in Lower Saxony and the implementation of the EC Marine Strategy Framework Directive (MSFD).

For evaluations and reporting, standardized data and metadata available via the Internet play a central role. In addition to data provision, the MDI-DE is to support the reporting obligations (WFD, MSFD, INSPIRE) in order to be able to complete the tasks faster, more effectively and more cost-efficiently through better networked data sources.

Cooperation in the provision of data with the Lower Saxony Wadden Sea National Park Administration (NLPV) is being expanded within the framework of MDI-DE. NLWKN and NLPV appear together for Lower Saxony in the VKoopUIS project and provide a common data node.

Half of the annual budget is provided by the federal government and half by the coastal states and is calculated according to the BLV Combating Marine Pollution (see HavKomErVbgG SH, Annex 2, §8).


In 2001, the Federal Ministry for the Environment and the Ministries of the Environment of the Federal States concluded the agreement on cooperation in the conception and development of software for environmental information systems (VKoopUIS). Under this umbrella, projects in the field of environmental information systems are carried out jointly by partners.

MDI-DE was established in 2010 – 2013 as a network of distributed infrastructure nodes in a KFKI research and development project funded by the Federal Ministry of Education and Research (BMBF). After project completion, partners from the federal government and the coastal states concluded an open-ended administrative agreement (VKoopUIS Project 49) in 2014 for the operation, maintenance and further development of the MDI-DE and agreed on future funding, organizational form and scope of services.
