Activities

The DGIWG standards development activities are grouped into one of five Technical Panels, each addressing multiple projects. The work of the Technical Panels is described below.

  • Vector Data
    DGIWG will create and maintain standardisation artifacts as part of the NATO Geospatial Information Framework (NGIF). NGIF’s purpose is to ensure interoperability between NATO, NATO Nations, and non-NATO Nations by defining a common standardized data model for the production, exchange and use of data and standard products, thereby enabling the concept of “fighting off the same map.” NGIF’s framework consist of a set of standardisation artefacts that are largely based on the ISO‘s 191xx series of standards for Geographic Information/Geomatics. Extensions to the ISO standards are incorporated in the NGIF as needed in order to address NATO’s existing and future needs.

    The framework provides NATO, NATO Nations, and non-NATO Nations a baseline set of standardisation artefacts to utilise and build upon, in turn increasing future information coherence and interoperability.
  • Imagery and Gridded
    Standardization of Imagery and Gridded Data (IGD) and related web services will be addressed through the development of standard data models and respective encodings (e.g. JPEG 2000). This will permit the design and development of standard data and products that are required to meet existing and future warfighter needs, especially for high resolution.

    DGIWG will reuse, as much as possible, the public domain standards, such as ISO and OGC standards for geo-referenced imagery. Coordination and collaboration with ISO and OGC will be conducted in order to address gaps and shortfalls identified by the military community. This also extends into NATO, especially in the area of JISR (Joint Intelligence, Surveillance & Reconnaissance) where joint interest in imagery standardisation lies.
  • Metadata
    The DGIWG will work to improve the discovery, evaluation, use and management of geospatial information and services within and among NATO, NATO Nations, and non-NATO nations through the development of common metadata standards. While the standardization of the form and meaning of metadata is critical for the efficiency in retrieving relevant and accurate information, the diversity of geospatial information and user requirements needs to be addressed. Work includes:
    • Coordinate and influence the civilian standardization work on metadata to ensure that military needs are met
    • Coordinate and support DGIWG projects regarding metadata
    • Support military activities and address military requirements with respect to metadata
    • Provide guidelines and best practices related to metadata
    • Provide and maintain a metadata vision promoting a standards-based approach and defining a framework to further analyse the need for military specific standards and specifications.
  • Portrayal
    The DGIWG will create and maintain a set of symbols for geospatial products that are produced in accordance with the standardisation artefacts under the NGIF. As products are defined specific rulesets will be created to be used with digital display, or for paper products as needed. Common symbology and marginalia information for set products will significantly reduce the interpretive errors created by the end user as products are exchanged amongst multinational forces.
  • Web Services
    The DGIWG will create and maintain standards and implementation profiles for geospatial web services which foster the discovery, retrieval, exchange, and use of geospatial data and products. It will address the technical issues related to geospatial information services, respective interfaces, and required formats. Where possible public domain standards based on ISO and OGC standards will be used or profiled.
