The centre for International Digital Elevation Models is one of six centres of the International Gravity Field Service (IGFS) of the International Association of Geodesy (IAG). The other five Centres are

  • Bureau Gravimetrique International (BGI) at CNES / CRGS, Toulouse, France
  • Internation Centre for Global Earth Models (ICGEM) at Potsdam, Germany
  • International Centre for Earth Tides (ICET) at Obs. Royal de Belgique, Brussels, Belgium
  • International Geoid Service (IGeS) at Politecnico di Milano, Milan, Italy
  • Technical Support Centre of IGFS at NGA, Saint Louis, USA

  • The IAG International DEM (Digital Elevation Model)service website provides a focus for distribution of data and information about Digital Elevation Models, relevant software and related datasets (including representation of Inland Water within Digital Elevation Models) which are available in the public domain. Currently this site hosts the ACE GDEM, and has links to a number of Global Digital Elevation Models. Information on analysis of the SRTM dataset will be added as it becomes available.

    As one of the aims of this site is to facilitate dissemination of information to the global community; please tell us about publications relevant to Digital Elevation Model analysis and quality control so we can include information about them on the website.
