1. The INTERNATIONAL ASSOCIATION OF GEODESY, hereafter called the Association or the IAG, is a constituent Association of the International Union of Geodesy and Geophysics, hereafter called the Union or IUGG, and is subject to the Statutes and Bylaws of the Union as well as to these Statutes.

2. The MISSION of the Association is the advancement of geodesy, an earth science that includes the study of the planets and their satellites. The IAG implements its mission by advancing geodetic theory through research and teaching, by collecting, analyzing, and modeling observational data, by stimulationg technological development and by providing a consistent representation of the figure, rotation, and gravity field of the earth and planets and their temporal variations.

3. The IAG shall pursue the following OBJECTIVES to achieve its mission:


  1. Study, at the highest possible level of accuracy, all geodetic problems related to the following:
  1. Support the maintenance of geodetic reference systems for continuous, long-term observations and archival of results.
  2. Provide observational and processed data, standards, methodologies, and models in a form that ensures the broadest possible range of research and application.
  3. Stimulate development and take advantage of emerging space and other technologies to increase the resolution and accuracy of geodetic data and products in order to advance geodetic and interdisciplinary research.
  4. Initiate, coordinate, and promote international cooperation and knowledge exchange through symposia, workshops, summer schools, training courses, publications, and other means of communication.
  5. Foster the development of geodetic activities and infrastructure in all regions of the world, taking into consideration the specific situation of developing countries.
