International Union of Geodesy and Geophysics [SEP] Introduction
The International Union of Geodesy and Geophysics (IUGG; , UGGI) is an international non-governmental organization dedicated to the scientific study of Earth and its space environment using geophysical and geodetic techniques. The IUGG was established in Brussels, Belgium in 1919. Some areas within its scope are environmental preservation, reduction of the effects of natural hazards, and mineral resources.
