IAG International Symposium on Reference Frames for Applications in Geosciences (REFAG 2022), Thessaloniki, Greece, October 17-20, 2022
The International Association of Geodesy and its services strongly condemn the unprovoked and premeditated Russian invasion of Ukraine. We are deeply troubled by the loss of life and hundreds of thousands of civilians becoming refugees, and are very concerned about the safety and well-being of our scientific colleagues in Ukraine. We strongly request that the responsible people stop the military actions immediately.
How does your cell phone know where you are right now? How is our planet changing due to geodynamic processes and ongoing climate change? How can these changes be precisely measured from space?
Do you know what geodesy is exactly and what GGOS does? This film immerses you in the world of geodesy and outlines its benefits for society.
The Tour de l’IGS is a series of virtual workshops on relevant topics to the IGS membership, stakeholders and GNSS community in general. These events will be hosted several times a year and will cover a wide range of topics including space-borne and ground-based instrumentation, technology development, scientific and societal applications, etc.
The International Association of Geodesy (IAG) is a scientific association in the field of geodesy. It promotes scientific cooperation and research in geodesy on a global scale and contributes to it through its various research bodies. It is a constituent association of the International Union of Geodesy and Geophysics (IUGG). IAG has a long and distinguished history that goes back to 1862, the year, in which the "Mitteleuropäische Gradmessung" was established. This organization was formed to promote scientific work in geodesy in Central Europe, following a proposal made a year earlier by J.J. Baeyer (1861). In 1867, the name of the organization was changed to "Europäische Gradmessung", because by then countries from all of Europe had joined the organization. In 1886, the name was changed to "Internationale Erdmessung", emphasizing the need for international cooperation to solve the scientific tasks of geodesy. The French and English translations of this name resulted in the current name "International Association of Geodesy (IAG)". Thus, the IAG as an international scientific organization goes back to 1886 and is one of the oldest international associations of this kind.
The Mission of the Association is the advancement of geodesy. IAG implements its mission by furthering geodetic theory through research and teaching, by collecting, analyzing, modelling and interpreting observational data, by stimulating technological development and by providing a consistent representation of the figure, rotation and gravity field of the Earth and planets, as well as their temporal variations.
