International scientific organization

IAG/IUGG - International Association for Geodesy

IAG/IUGG was created in 1862 under the name of 'The Mitteleuropäische Gradmessung' (Central European Arc Measurement) and was the first international scientific organization to be acknowledged. In 1867 it expanded and became the 'Europäische Gradmessung' (European Arc Measurement) and, in 1886, it became the 'Internationale Erdmessung' (International Association of Geodesy, Association Internationale Géodésique). At IUGG first General Assembly (Rome, May 2-10, 1922) it became one of IUGG’s five sections. Its current name was decided during IUGG General Assembly held in Stockholm in 1930.

IAG mission is the advancement of geodesy expressed with the promotion of the geodetic theory through research and training, through the collection, analysis, modeling and interpretation of the observed data, the stimulation of technological development and representations of images, rotation and gravity field of the Earth and Planets and their temporal variations.

Its objectives include the study of all geodetic problems related to “Earth observation and global change”. This includes the establishment of reference systems, monitoring the gravity field and the earth's rotation, the deformation of the earth's surface -including ocean and ice- and placement for an interdisciplinary use. IAG intends to initiate, coordinate and promote the exchange of knowledge and international cooperation through symposia, seminars, summer schools, publications and other tools. Its goal is to promote the development of geodetic activities and infrastructures around the world.

IAG's activities are divided into the following subjects:

  • Committee 1: Reference Frames
  • Committee 2: Gravity Field
  • Committee 3: Geodynamics and Earth Rotation
  • Committee 4: Positioning and Applications
  • Inter-committee Committee on Theory
  • Global Geodetic Observing System (GGOS)
  • 14 International Scientific Services

IAG is one of the eight associations within the 'International Union of Geodesy and Geophysics (IUGG).
