Vistas for Geodesy in the New Millennium

This volume contains 102 papers from the IAG Scientific Assembly, held on the premises of the Hungarian Academy of Sciences in Budapest from 2nd to 7th September, 2001. These assemblies are designed to give an integrated view of geodetic activities to a broad spectrum of researchers and practitioners in geodesy and geophysics. At this meeting, which emphasized new vistas, a total of 380 papers were presented in four symposia and three special sessions. The topics embraced:- Fine-tuning Reference Frame Implementation- From Eötvös to Satellite Gradiometry - New Vistas in Measuring and Modeling the Earth's Gravity Field- Geometry and Beyond - Using Global Navigation Satellite Systems (GNNS) in New Ways- Modeling Earth's Processes and Global ChangeOf the 380 papers presented, about 100 were selected for review and publication in this volume. They are representative of this meeting in that they present current research areas in geodesy to the interested geophysicist and new research challenges to the geodetic specialist.

It was in September 1906 that the predecessor of the IAG, the 'Internationale Erdmessung', th organized the 15 General Assembly at the Hungarian Academy of Sciences in Budapest. It was 95 years later, in September 2001, that the IAG returned to this beautiful city to hold its Scientific Assembly, IAG 2001, in the historical premises of the Academy. The meeting took place from September 2-7, 2001 and continued the tradition of Scientific Assemblies, started in Tokyo (1982) and continued in Edinburgh (1989), Beijing (1993) and Rio de Janeiro (1997). Held every four years at the midpoint between General Assemblies of the IAG, they focus on giving an integrated view of geodesy to a broad spectrum of researchers and practitioners in geodesy and geophysics. The convenient location of the main building of the Hungarian Academy in downtown Budapest and the superb efforts of the Local Organizing Committee contributed in a major way to the excellent atmosphere of the meeting. As at previous meetings, the scientific part of the program was organized as a series of symposia which, as a whole, gave a broad overview of actual geodetic research activities. To emphasize an integrated view of geodesy, the symposia did not follow the pattern of the IAG Sections, but focussed on current research topics to which several IAG Sections could contribute. Each symposium had 5 sessions with presented papers and poster sessions on two consecutive days.
