The Hotine-Marussi Symposium is the core meeting of a "think thank", a group scientists in the geodetic environment working on theoretical and methodological subjects, while maintaining the foundations of geodesy to the proper level by  corresponding to the strong advancements improved by technological development in the field of ICT, electronic computing, space technology, new measurement devices etc.
The proceedings of the symposium cover a broad area of arguments which integrate the foundations of geodesy as a science. The common feature of the papers therefore is not on the object, but rather in the high mathematical standards with which subjects are treated.
