Overview
The precursors to the IAG were
arc measurement
Arc measurement, sometimes degree measurement (german: Gradmessung), is the astrogeodetic technique of determining of the radius of Earth – more specifically, the local Earth radius of curvature of the figure of the Earth – by relating the la ...
campaigns. The IAG was founded in 1862 as the ''Mitteleuropäische Gradmessung'' (Central European Arc Measurement), later became the ''Europäische Gradmessung'' (European Arc Measurement) 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.
Journal
IAG sponsors the ''Journal of Geodesy'', published by Springer as the merger and continuation of ''Bulletin Géodésique'' and ''manuscripta geodaetica''; it has an
impact factor
The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index calculated by Clarivate that reflects the yearly mean number of citations of articles published in the last two years in a given journal, as ...
