International Association of Geodesy IAG
Advancing Geodesy to Understand and Protect the Earth for a Sustainable Future
The International Association of Geodesy (IAG), a constituent association of the International Union of Geodesy and Geophysics (IUGG), is a global scientific organisation promoting geodetic research and cooperation. Founded in 1862, it has grown from a regional initiative to a worldwide association emphasising collaboration in solving geodetic challenges. The mission of the IAG is to advance geodesy through research, data analysis, technology development and the provision of accurate representations of the Earth.
IAG’s Global Observing System | Geodesy for Earth Science and Society
The Global Geodetic Observing System (GGOS) of the International Association of Geodesy (IAG) provides the essential framework for accurate measurements and consistent modelling and interpretation of Earth system processes and interactions, including global change, Earth deformation, and mass exchange between and within the geosphere, biosphere, cryosphere, hydrosphere and atmosphere.
