IAG History

UN General Assembly urges sharing of geospatial data to benefit people and planet

The science that supports the precise pinpointing of people and places should be shared more widely, according to the United Nations General Assembly as it adopted its first resolution recognizing the importance of a globally-coordinated approach to geodesy the discipline focused on accurately measuring the shape, rotation and gravitational field of planet Earth. For more information, please click here!


IAG History

The International Association of Geodesy celebrates its 150th Anniversary in 2012. In order to celebrate these memorable years, several documents focusing on the history of Geodesy and our Association will be published on the IAG Website throughout the year.

The GOCE Geoid

After the second year on orbit, the ESA's GOCE satellite collected enough data to model the Earth's gravity field with unprecedented precision.

Prof. Reiner Rummel said, "We see a continuous stream of excellent GOCE gradiometry data coming in. With each of the two-month cycle, our GOCE gravity field model is getting better and better." For more information, please click here!

Welcome to the International Association of Geodesy

The International Association of Geodesy (IAG) is a scientific organization 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 an active member of the International Association of Geodesy and Geophysics (IUGG) which itself is a member of the International Council for Science (ICSU).
The 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 organizations of this kind.

Mission

The Mission of the Association is the advancement ofgeodesy. The IAG implements its mission byfurthering geodetic theory through research andteaching, by collecting, analyzing, modelling andinterpreting observational data, by stimulating technological development and by providing a consistent representation of the figure, rotation, and gravity field ofthe Earth and planets, and their temporal variations.
