The database on offshore military areas in the EU was created in 2020 by CETMAR for the European Marine Observation and Data Network (EMODnet). It is the result of the aggregation and harmonization of datasets provided by several sources. It is updated every year and is available for viewing and download on EMODnet Human Activities web portal (https://emodnet.ec.europa.eu/en/human-activities). The database contains points and/or (where available) polygons representing offshore military areas in the following countries: Belgium, Bulgaria, Denmark, Estonia, Finland, Germany, Greece, Ireland, Latvia, Lithuania, Netherlands, Poland, Portugal, Spain and Sweden. Each polygon/point has the following attributes (where available): Country, Country_2, Country_3, Status (Active, Deactivated, Unknown, Planned), Type_1 (Firing Area, Air Force Exercise, Surface Exercise, Underwater Exercise, Mine Hunting Exercise, National Defence Area), Type_2, Type_3, Resource, Distance to coast (metres) and Area (square kilometres). The distance to coast (EEA coastline shapefile) has been calculated using the UTM WGS84 Zone projected coordinate system where data fall in.

The dataset on offshore pipelines in the EU was created in 2017 by Cogea for the European Marine Observation and Data Network (EMODnet). It is the result of the aggregation and harmonization of datasets provided by several sources from all over the EU (plus Norway). The database contains lines representing the actual routes of offshore pipelines (where available) in the following countries: Croatia, Denmark, Estonia, Finland, Germany, Ireland, Netherlands, Norway, Poland, Russia, Spain (Andalucía), Sweden and United Kingdom. Each line has the following harmonized attributes (where available): code, name, status (abandoned, active, application submitted, not in use, planned, pre-commissioning, proposed, under construction), medium (air, chemical glycol, chemical methanol, chemical n/a, condensate, control, cooling water, gas, geothermal heating, hydraulic, mixed hydrocarbons, oil, other fluid, sewage, water), operator, size (inches), length (metres), year, from and to locality or facility, country code, country name and notes. Compared with the previous version, this new version includes updated data from Helcom and Nord Stream 2 sources.

The datasets on subsea telecommunication and power cables (actual routes) in the EU was created in 2014 by Cogea for the European Marine Observation and Data Network (EMODnet). It is the result of the aggregation and harmonization of datasets provided by several sources. It is updated every year and is available for viewing and download on EMODnet Human Activities web portal (https://emodnet.ec.europa.eu/en/human-activities). The datasets contain lines representing actual cable routes locations. Compared with the previous version, this version includes an update of the French telecommunication cables, the telecommunication cables that originate from or pass through Spanish (Andalucia) and Dutch waters, and the electric cables that originate from or pass through French, Dutch and Norwegian waters.
