Terms of Reference

The Inter-Commission Committee on Theory (ICCT) was formally approved and established after the IUGG XXI Assembly in Sapporo, 2003, to succeed the former IAG Section IV on General Theory and Methodology and, more importantly, to interact actively and directly with other IAG entities. In accordance with the IAG by-laws, the first two 4-year periods were reviewed in 2011. IAG approved the continuation of ICCT at the IUGG XXIII Assembly in Melbourne, 2011. Recognizing that observing systems in all branches of geo-desy have advanced to such an extent that geodetic mea-surements (i) are now of unprecedented accuracy and quality, can readily cover a region of any scale up to tens of thousands of kilometres, yield non-conventional data types, and can be provided continuously; and (ii) conse-quently, demand advanced mathematical modelling in order to obtain the maximum benefit of such technological advance, the ICCT (1) strongly encourages frontier mathematical and physical research, directly motivated by geodetic need and practice, as a contribution to science and engineering in general and the theoretical foundations of geodesy in particular; (2) provides the channel of commu-nication amongst the different IAG entities of commis-sions/services/projects on the ground of theory and methodology, and directly cooperates with and supports these entities in the topical work; (3) helps the IAG in articulating mathematical and physical challenges of geo-desy as a subject of science and in attracting young talents to geodesy. The ICCT should strive to attract and serve as home to mathematically motivated/oriented geodesists and to applied mathematicians; and (4) encourages closer research ties with and gets directly involved in relevant areas of the Earth sciences, bearing in mind that geodesy has always been playing an important role in understand-ing the physics of the Earth.

Objectives

The overall objectives of the ICCT are to act as international focus of theoretical geodesy, to encourage and initiate activities to advance geodetic theory in all branches of geodesy, to monitor developments in geodetic methodology. To achieve these objectives, the ICCT interacts and collaborates with the IAG Commissions, GGOS and other IAG related entities (services, projects).
