  • Ensuring the maintenance of guidance documents specifically targeted towards the UN-GGIM, such as
          -   The Standards guide and its companion document, developed for UN-GGIM by ISO/TC 211, OGC, and IHO
           -   The Strategic Pathway on Standards, as part of UN-GGIM Integrated Geospatial Information Framework (IGIF), Part 2 Implementation guide (IGIF/Strategic Pathway 6, SP6)
  • Reporting to and participation at the annual sessions of UN-GGIM
  • Reaching out to the UN-GGIM community - the committee, the expert and working groups, thematic groups, and regional groups - by monitoring their needs and raising awareness

The participation of ISO/TC 211 in the work of UN-GGIM is essential. The group is open to members appointed by Member bodies or liaison organizations. The result of the work is presented as recommendations to ISO/TC 211.

AHG 6 - Ad Hoc Group on digital transformation of public administration (e-Government)*

Noting that most other domains will need standardized geospatial components, now or in the future, the goal for ISO/TC 211 in location enabling in other domains is to:

- be the ISO entry point to geospatial standards;

- develop and maintain an aligned set of standards, focused on the geospatial context;

-provide and recommend geospatial standards for use in other domains, that are accepted and applicable for integration with other standards without re-modelling.

Noting the digital transformation of public administration often needs location information, ISO/TC 211 wants to help to do that in an open standard way. Location data and SDIs underpin transformation towards Digital Government.

Since location is regarded as a generic topic and not specific to the geospatial domain, we need to look at how geospatial standards can be applied in handling location information in other domains. Digital transformation of public administration, due to its widespread implication on other domains, is a good starting point to examine this issue, and ISO/TC 211 resolves to establish an Ad hoc group (AHG) on digital transformation of public administration.

ISO/TC 211 resolves to establish an ad hoc group on digital transformation of public administration.

Terms of Reference for an AHG on digital transformation of public administration:

“The focus on digital transformation of public administration will increase the knowledge on how the needs of other domains have impact on the work of ISO/TC 211. The AHG will address issues on the content of the standards and models, rather than the issues of outreach. It is important to consider the work of other SDOs. The AHG will:

- describe the situation today: identify the ISO/TC 211 standards applicable for digital transformation of public administration;

- describe the situation we want to achieve based on the goals above, and on the experiences of digital transformation of public administration;

- describe how to get there: by recommending an interoperability approach and the consequences for the committee.”

Convenor: Mr Morten Borrebaek (Appointed 2020-08)
