    [Establishment of DGIWG]

    The Digital Geographic Information Working Group (DGIWG) was established in 1983 to develop standards to support the exchange of Digital Geographic Information (DGI) among NATO nations. The DGIWG is not an official NATO body; however, the DGIWG's standardization work has been recognized and welcomed by the NATO Geographic Conference (NGC). Interoperability and burden sharing among nations are the goals of the group.

    [Scope of Work]

    DGIWG developed and maintains DIGEST as an exchange standard to facilitate the exchange of DGI to support interoperability within and between nations, and burden sharing of digital data production. The scope of this activity includes dataset specification development and harmonization of standards. Of particular interest are the harmonization of DIGEST with the NATO Secondary Imagery Format (NSIF) and the harmonization of DIGEST with the International Hydrographic Organization S-57 data. DGIWG is working closely with ISO TC 211 in the development of International Geospatial Standards and the migration of DIGEST as a profile of the ISO standards. DGIWG liaises closely with other standardization and geospatial requirement organizations. DGIWG is active in coordinating common requirements and national initiatives relating with data access services, data quality, and metadata.
