Years of research in the fields of science and technology associated with observation and understanding of the processes and phenomena of the terrestrial environment led in 1998 to the idea to launch GMES. By a combination of measurements at terrestrial level and from space, it rapidly became clear that new operational services could be offered in fields such as oceanography, precise mapping of land use, rapid mapping at times of emergency for the civil protection field or air quality monitoring.

The progressive implementation of GMES is made possible by the activities and investments of European Union and ESA Member States. These and other public and private contributions are jointly supported by the European Commission (EC) and the European Space Agency (ESA).
