"This volume contains a selection of 99 papers from the International Association of Geodesy (IAG) quadrennial General Assembly, held in Perugia, Italy, from July 2 to 13, 2007, in conjunction with the XXIV General Assembly of the International Union of Geodesy and Geophysics (IUGG). There were 225 oral and 474 poster presentations made at the five IAG Symposia, which covered the following research themes: Reference Frames; Gravity Field; Earth Rotation and Geodynamics; Positioning and Application; and The Global Geodetic Observing System (GGOS)." "The Symposia focused on Earth observation and the three pillars of geodesy (geometry, Earth rotation, gravity field), and the presented topics spanned a broad and multidisciplinary spectrum of theory and applications. It was clearly evident that, with the recent advances in space missions such as GRACE, geodesy can now contribute to the detection of large-scale temporal phenomena and hence, to the solution of important problems of society related to monitoring our environment and understanding global change. Therefore, the title of this volume, "Observing our Changing Earth", was chosen to reflect this fact, as well as to agree with the general theme of the 2007 IUGG General Assembly, "Earth: Our Changing Planet"."--Jacket.

This symposium continued the tradition of mid-term meetings held between the joint symposia of International Geoid and Gravity Commissions. This time, geodynamics was chosen as the third topic to accompany the traditional topics of gravity and geoid. The symposium thus aimed at bringing together geodesists and geophysicists working in the general areas of gravity, geoid and geodynamics. Besides covering the traditional research areas, special attention was paid to the use of geodetic methods for geodynamics studies, dedicated satellite missions, airborne surveys, geodesy and geodynamics of arctic regions, and the integration of geodetic and geophysical information.
