NKG (The Nordic Geodetic Commission, founded in 1953) is an association of geodesists from Denmark, Finland, Iceland, Norway and Sweden. Its purpose is to give the members possibilities of fruitful gatherings and mutual exchange of professional views and experiences. The NKG is recognized and supported by a number of Nordic organizations, such as the Director Generals of the Nordic Mapping Authorities (See bylaws). In order to forward its vision, the Commission arranges general meetings every 4 years, and summer schools also every 4 years, in one of the Nordic countries as the host. NKG is managed by a Presidium and the actual work is done in Working groups and Working group projects.

NKG is currently very active, and has a strong project oriented focus and has a long history and tradition. The NKG has during the years coordinated many tasks related to improved and joint geodetic infrastructure in the Nordic area.

NKG has proven many times that the cooperation is needed and that it has been successful. Current examples of very important NKG projects are an improved Nordic geoid model, a new empirical land uplift model, a joint GNSS analysis centre, the joint gravity database and a common transformation method.

NKG has also been visible in international initiatives, e.g. in EUREF work. The NKG has been many years a local analysis centre contributing to the EUREF Permanent Network (EPN), a European wide network of permanent GNSS reference stations. Another example is the EUREF working group of deformation models where the Nordic geodetic challenges on post-glacial rebound have been successfully brought out into the European awareness.

NKG has the following working groups:
