WORKING MEETING OF THE IAG SSG 4.190 ON NON-PROBABILISTIC ASSESSMENT IN GEODETIC DATA ANALYSIS

The first working meeting of the IAG SSG 4.190 took place at the Geodetic Institute, University of Karlsruhe (GIK), on April 7, 2000. 11 members and corresponding members were participating. The meeting was opened with a welcome note by B. Heck, president of the IAG Section IV on General Theory and Methodology. H. Kutterer, chairman of the SSG, continued with a short review of the terms of reference and objectives. The main part of the meeting consisted of oral presentations by members of the SSG on the topics fuzzy-theory (E. A. Shyllon, K. Heine), robust estimation (A. Carosio), artificial neural networks (J. B. Miima), interval mathematics (S. Schön), GIS for local geoid computation (M. Brovelli), and on general uncertainty theory (H. Kutterer).

It was decided to have annual closed working meetings of the SSG. Besides, it is planned to organize an open international workshop on robust and fuzzy techniques in March 2001 in Zürich.

The financial support of the stay of E. A. Shyllon by the IAG is gratefully acknowledged as well as the sponsoring of the organization of the meeting by the GIK.
