High-quality maritime spatial planning, coastal zone management, management of marine resources, environmental assessments and forecasting require comprehensive understanding of the seabed. In response to the needs already in 2008, the European Commission established the European Marine Observation and Data Network (EMODnet). The EMODnet concept is to assemble existing but often fragmented and partly inaccessible marine data into harmonised, interoperable, and publicly freely available information layers which encompass whole marine basins. As the data products are free of restrictions on use the program is supporting any European maritime activities in promotion of sustainable use and management of the European seas. EMODnet-Geology project is delivering integrated geological map products which are aimed to be user friendly for public administration, research and education, maritime industry, and the general public.
