The U.K. Defence Intelligence Joint Environment (DIJE) provides strategic direction, policy, and guidance on four-dimensional environmental information (EI) and imagery management, requirements, and capabilities to the Ministry of Defence (MOD) central staffs, commands, agencies, and related organizations. DIJE integrates output from the four existing principal U.K. Defence EI providers — the Defence Geographic and Imagery Intelligence Agency, the U.K. Hydrographic Office, the Meteorological Office, and the No. 1 Aeronautical Information and Documentation Unit.
The DIJE acts as a single joint directorate to provide vision and formulate policy for EI and imagery management across U.K. defense. The DIJE also coordinates MOD relationships with other government departments and other organizations arising from bilateral and international agreements relating to EI, IMINT, and MASINT.
