Global Monitoring for Environment and Security: data policy considerations

Data policy is an important element of the initiative on Global Monitoring for Environment and Security (GMES), which aims to establish a European capacity for the provision and use of operational information for monitoring and management of the environment and civil security by 2008. This paper documents the data policies of the variety of information providers likely to be involved in GMES, identifies the obstacles and draws conclusions on ways to improve data policy coherence. It addresses the main policy issues associated with Earth observation data, as well as with other types of environmental data.
