Contributing National Organisations to IAG
The International Association of Geodesy (IAG) strongly relies on its contributing organizations, which provide essential support in various ways. These organizations contribute expertise, personnel, and funding to sustain geodetic observatories, analysis centers, data centers, and many other critical components of geodetic research and operations. Their collaboration ensures the advancement of geodetic science and the development of high-quality global geodetic products.
