International Geoid Service


President: Mirko Reguzzoni (Italy)
Director: Giovanna Sona (Italy)

IGeS has been founded in 1992 as a working arm of International Geoid Commission (IGeC), and it is actually an official Service of the International Association of Geodesy (IAG).

Since 1999 the process of reviewing statutes of IAG has deeply involved also the IAG Services and those Services which are related to the determination of the gravity field.
In 2003, a new unified IAG Service for the Gravity Field has been created: the International Gravity Field Service (IGFS), to coordinate and integrate broad gravity field activities.
IGFS centres are: International Gravimetric Bureau (BGI), International Geoid Service (IGeS), International Center for Earth Tides (ICET), International Centre for Global Earth Models (ICGEM) and International DEM Service (IDEMS). In IGFS, IGeS is one of the operative arms of the International Commission for the Gravity Field.

IGeS' activities are on educational, research, and data distribution sides: principal purposes of IGeS are the collection and distribution of geoid models, the collection and distribution of software for geoid computation, and the organization of technical schools on geoid determinations.

The Service is provided by two Centres, one at Politecnico di Milano, and one at NIMA (contact person S. Kenyon)

Main tasks of IGeS are:

• to collect geoid data on a worldwide scale (geoid repository)
• to collect and distribute software for geoid determination (software download)
• to conduct researches on procedure for geoid determination (projects)
• to organize Geoid schools
• to edit and distribute the Newton's Bulletin

Moreover, as regards the research activity, IGeS takes part in:

• the European Gravity Geoid Project
• the GOCE satellite mission
• the Global Geodetic Observing System project (GGOS) for the height datum unification

At present the following scientists are IGeS advisors:
R.Forsberg, C.C. Tscherning (Denmark), M. Sideris (Canada), W. Kearsley (Australia), S. Kenyon, N. Pavlis (USA), H. Denker (Germany), U. Marti (Switzerland), E. Tziavos (Greece), A.J. Gill (Spain), D. Blitzkow (Brasil).

Within the structure of IGeS, Working Groups can be established for specific purposes, limited in time.
