The International Association of Geodesy (IAG) is a constituent association of the International Union of Geodesy and Geophysics. It was founded in 1862 as the Mitteleuropäische Gradmessung, later became the Europäische Gradmessung in 1867, the Internationale Erdmessung (Association Geodésique Internationale in French and "International Geodetic Association" in English) in 1886 and took its present name in 1946.
At present there are 4 commissions and one inter-commission committee:
- Reference Frames
- Gravity Field
- Geodynamics and Earth Rotation
- Positioning & Applications
- Inter-commission Committee on Theory
The Global Geodetic Observing System (GGOS) is the observing arm of the IAG that focuses on proving the geodetic infrastructure to measure changes in the earth's shape, rotation and mass distribution.
