Maritime surveillance authorities and sectors deal with different kinds of data, including entity (e.g. ship register or crew lists), traffic (e.g. declared origin or density), spatial (e.g. passageways or hydrography), and event management data (e.g. accident or landing of dangerous cargoes), as well as their associated metadata (e.g. police reports or fisheries legislation) and information about meteorological conditions or environmental parameters, among others.
CISE enables the sharing of all types of maritime information, also information which can be exchanged between civil and military organizations. The information shared can be both classified and not classified information. The actual information exchanged depends on what information CISE participants will offer.
