IAG + GGOS Geodesy

This is the official YouTube channel of the International Association of Geodesy (IAG) and its component Global Geodetic Observing System (GGOS).

The International Association of Geodesy (IAG), founded in 1862, is a global scientific organization dedicated to measuring and understanding Earth’s shape, gravity field, and rotation. As part of the International Union of Geodesy and Geophysics (IUGG), IAG plays a vital role in advancing geodetic science and its applications for society.

Within IAG, the Global Geodetic Observing System (GGOS) serves as the coordinating body that integrates geodetic observations worldwide. GGOS provides the precise, reliable data and reference frames needed to monitor Earth’s dynamic system—supporting climate research, natural hazard assessment, navigation, and more.

Together, IAG and GGOS enable cutting-edge Earth science that informs policy, technology, and global cooperation.
