Achievement of Interoperability
Requirements Definition: Interoperability requirements will guide
DGIWG standardization activities. DGIWG will guide member nations
in their pursuit to be knowledgeable of interoperability requirements
for geospatial support of their C4I operational community. These
requirements will be gathered and analyzed to determine the current
levels and future desired levels of geospatial interoperability.
The migration path to these new levels will be summarized in Specific
Interoperability Objectives. DGIWG will develop an architecture
to provide a holistic framework for operational requirements, interoperability
objectives, and standards development, test, demonstration and transition.
Outreach Program: As part of an Outreach Program, DGIWG will develop
a few tangible and practical information products by making use
of national initiatives that are already in place. These products
will be directed at end users to increase their awareness of DGIWG
standards, and develop on-line tools that enable end users to generate
these information products. The developers of standards, documentation
and products will be assigned the responsibility for their maintenance.
DGIWG will provide a web-based environment to enable its members
and external cooperators to exchange information on geospatial standards
and their operational use. DGIWG will develop appropriate documentation
to guide the adoption and use of its standards.
Demonstration: DGIWG will actively participate in available operational
demonstration environments suitable for all members and use these
environments as a major mechanism of standards out-reach to the
Operational Transition: DGIWG will track the progress of standards
adoption and use in the operational community.
Links with External Organizations: DGIWG will collaborate with
standards bodies such as ISO, IHO and OGC on standards
Links with NATO: DGIWG will collaborate with NATO and its subordinate
panels and working groups to address military unique requirements for
geospatial data, products, and services.
Links with Industry: DGIWG will liaise with the geospatial and
defence systems vendor communities to promote implementation of
DGIWG standards and to maintain awareness of vendor developments.
Use of International Standards: DGIWG will adopt or profile ISO
base standards to the largest degree practical. International standards
originating from other geospatial communities will be considered
as well, such as those originating from OGC, when no practical ISO
standards exist. These standards will be made more concrete, locked
down as a version in time, and made openly available as a DGIWG-branded
standard. This process is similar to a nation adopting an
ISO standard and making it a national standard.
Information Management: DGIWG will focus on the development of
geospatial standards in information management in areas such as
metadata, elevation, encoding, feature and attribute registries
and feature catalogues, general feature model, imagery and gridded
data, portrayal, quality, reference systems, and spatial-temporal
Services: DGIWG will focus on the development of geospatial standards
for services and interfaces by developing a) a services architecture,
b) a few core operational services for wide use by member nations,
and c) standard procedures for geospatial information required for
Co-Production: DGIWG will not undertake co-production, but it will
undertake activities in specification development that will support
Testing: DGIWG will adopt a prototype test strategy for open use
by all members.
Organization: DGIWG is a two-tiered organizational structure bringing
together people who are responsible for policy and resource management
with those who lead, manage, and work the technical program.
Use of Resources: DGIWG will identify specific activities to member
nations as opportunities for participation. Where possible, these
activities will tie closely into national initiatives.
